Parvo Vaccine

Our 10 week old husky puppy had her parvo vaccine yesterday. About a minute and a half after being injected she went into a grandmaul seizure. The vet said he'd NEVER heard of that happening before and he said he's pretty sure she has epilepsy. It was the SCARIEST thing I've ever been through, she seized in my arms. After looking through all these responses and all Im even more firm on my belief that the shot caused the seizure. So far she's not had anymore. But we will be trying the Coliander leaves in her food, and are waiting to hear from the vet to see if DSMO or whatever is aproved for dogs in our state. If so we will be trying that too to make sure there is no long term effects. We LOVE this puppy and dont want to lose her. So a warning to other husky owners, BEWARE.

I had 2 bichon friese/malteseX, 9 yo, bro/sis, both in perfect health. In Sep, 2007 I took them for their annual parvo vaccinations. Suddenly, 2 months later the female is totally blind & the male is blind in the left eye. She also lost weight & was diagnosed diabetic. He had a major seizure & was diagnosed epileptic. I will never have my beloved dogs or any dogs I may own in the future, vaccinated ever again.

I am sorry, I now know what I thought was impossible. Two siblings, a boy and a girl got their shots. The girl vomited for a week then starting losing weight fast and stopped eating. Her gums and ears turned yellow (liver problem). Shortly after, her brother started having the same symptoms. He was put on anti-biotics. He hasn't gotten better, won't eat, won't defecate, won't move, won't pee, nothing. We are saddened that tomorrow we take him to be euthanized because his liver is failing. His sister, however, is finally eating small amounts and getting slowly better. This is atrocious!

I have a toy poodle who weighs 6 lbs. When he got his first rabies 1 year vaccine he only weighed 2 lbs. He had a reaction that involved his skin getting bright red after the shot which travelled down his hind quarters. Then the tips of both his ears became irritated and a week or so later looked like someone had tried to embroider the edges. I had to soak off all the scabs in warm bath water. A month later he lost all the hair in the area of his injection site. I went ahead a year later to give him his 3 year vaccine only this time he was given some medication prior to the injection to help with the inflammation I believe it was benedryl. He had the same reaction as before but it was not as severe as before. My vet and I decided after both reactions that he would no longer receive this vaccine.

My dog also reacted to the Lyme Disease vaccine by having a fever the day after that injection. I no longer give him this vaccine.

He is currently titered in between his vaccines and they are spread out during the year (Bordetallo is given at different times)

Go to a health food store and homopathic medicince - Thuja 30c. Start giving your dog asap 3-4 times a day 4-5 pellets.

Stop everything else. Feed light natural home cooked meals and also Apple Cider Vinegar and coconut oil as it helps the body detox.

I have 6 cats and a dog, 3 of the cats are from the same litter and are 2 years old. A few months ago near their 2 year mark, they were given their rabies and distemper shots. Before we were even in our car, one of them (Spidey) started convulsing, this triggered foaming of the mouth, loss of urine. We immediately rushed him into the vet's office again, where he was given a corticosteroid injection, I believe, for the reaction. Spidey had never had a single medical issue before this day. Of the 3 rescues he was always the strongest and biggest. Since this day, Spidey has had 3 more seizures that we know of. They cause him severe distress and wiped him out for over 24 hours. One time I did not think he would make it through. We of course took him to the vet who stated that they did not think the seizure was related to the shot (same vets who treated him the first time). Also they keep telling us that it would not benefit Spidey to treat him unless his seizures occur more frequently.

I am very scared for him, I want to make sure he has a healthy long life. When we found them as 1 month old kittens, they were half the weight they were supposed to be and nearly starved and dehydrated to death. Their mother we assumed was killed or picked up.

I hate to see him so wiped out. And my heart stops each time I see him suffering. I will never ever have him vaccinated again. The other cats do not seem to have any issues with the exceptions of dry long drawn out coughs. Again the vets dismiss this.

Not sure what has to happen to get the attention of the powers to be to investigate this phenomenon and determine to what extent these reactions occur.

Good for you. Merck has been in the news recently about the Home Again chip causing cancerous tumors. Vaccines are dangerous, just like they are for us & the yearly doses are not needed. Titering is a test to determine if needed.

You are correct & the Vet should be jailed for killing your dog with his/her GREED! It was pure Greed or Stupidity. Either way, put the cuffs on!

To Whitney from Virgina,

I am soooo sorry for your loss!I have lost many pets over the years. And it sucks basically. It hurts and you feel like your heart will break when you breathe. I wish that I could say something to make you feel better, but there is nothing. It does get better though, I promise. It still hurts when I think of all the critters that I have loved and lost over the years. But, not like it used to. I love animals! No matter what they are. I have been where you are and I am very sorry. I have heard that the spirits of animals and children go straight to where they are supposed to be because they are inocent and without sin. So yes,your little furry one is in Kitty heaven. I truly believe in this.

Hi, have you ruled out lack of exercise? My parents' german shepherd started having aggression issues around the same age and they finally brought a trainer in to help. The first thing the trainer did was tell them to walk the dog for at least 40 minutes a day! That worked fabulously as he wasn't getting enough exercise roaming the back yard. If your girl is getting plenty of exercise and still having aggression issues, then check into a deficiency of some kind in her diet that might be causing it. Good luck to you and please give us an update!

I'm responding to you for two reasons: 1) I too, once lived in New Braintree, Ma, & 2) My Son's beautiful orange&white male cat was just put down today! Went to a Vets office because of a small flea problem, received a steroid shot, & since he hadn't been in a while to the Vets received other shots. Also, I want to add, the Vet told my son, "Other than a small flea problem, your cat is in perfect health. " This visit was on a Thursday, by Monday we, my son and myself had to put him down!!!! HOW HORRIBLE!

My 4 year old Puggle had her rabies shot on Tuesday, noticed she was mellow that night but the next day she was lethargic, sore, wouldn't jump up or down on bed, and had a seizure called the vet they said to just watch her, by thursday she was moving down the stairs slower than normal and by friday when I got home from work she was completely paralyzed from the waist down. The vet that gave her the shot said they were closing early to take her to the animal hosp. Had an x-ray and they said it could be a back disc issue. It has been 2 days $600.00 later and they really dont know. She has no control over her bowel movements, we have to stand her up to pee and squeeze her stomach and as far as pooping, she just goes on herself and we have to clean her up. I just dont undertstand how we had a perfectly healthy dog and after the rabies shot everything went bad and they blame it on a disc. I think the vet hit a nerve or something. If anyone has any advice I would love to hear it.

I have had great success with Homopathic medicine to help my cats get over vaccines. Either find a homopathic vet or check with Dr. Pitcarn -

Or a homopath that works with a holistic vet in your area.

In case you are not aware of this: If your dog is unhealthy already you do not have to have them vaccinated. You should not give anyone or any animal a vaccine when they are sick or not healthy. Sorry about your pup.

Angel, I'm 99.99% sure that your Chihuahua doesn't have a cancer. My two Chihuahuas had their rabbies shot 2 years ago. One of them had a lump and I was told that it might be a cancer. I freaked out...and the doctor said to get blood test done first before we discuss about surgery. The blood test came back and it was fine. It turned out that she had allergy reaction to the rabbies shot. So, I warn you that Chihuahuas are very sensitive to those booster & rabbies shots. So, I would do research more on Chihuahuas before you do anything else. If you haven't had your Chihuahua's blood test done, go and do it. It will probably came back as negative.

Latest update on my belved Zsazsa. I wrote previously she was diagonosed with cancer at her rabies injection site, yes blood test confirmed it. Zsazsa was allergic to anesthesia and could't have surgery. The vet projected she may live 3 to 4 months. I just lost my little girl last week. Her tumor burst and had no choice but to put her down. It broke my heart. I asked the vet was there any way to know 100% her cancer was from the rabies vaccine and she said they could do a biospy and detemine. We also asked if our local college of vet. medicine would be interested in studing her cancer. Our vet contacted the company who produced the rabies vaccine and they have agreed to pay for the biospy to determine if their product caused the cancer and Michigan State University is going to do an autopsy and study her. If nothing else her number will be reported if it is found the rabies vaccine caused her cancer. I miss her dearly and want peple to know the dangers of this vaccine. I applaud the vet for going after the company to pay for the test and the company for stepping up to see if their poduct caused it.

EC: We are so sorry for your loss, Angel. Thank you for taking the time to update the site.

Have you tried goldenseal for your cats? I have 3 cats all 15 years old, all in good health. I give them a teaspoon of ACV a day in thier water dish. The only illness they have had is a uti in my female. She got cranberry juice in milk for about a week. I know they shouldnt have milk but that was the only way to get her to take it. cleared up a sinus infection in my tom with goldenseal applied to the scruff,have also used the ACV the same way. You may also want to look up activated charcoal for your kitten. If you need to know where to buy the goldenseal locally, since we live in the same area you can e mail me if you want. Hope all goes well.

Regarding the warning posted today. I have always heard that grapes/raisins and onions are toxic to dogs, but never garlic. In every natural or holistic animal book I have, the use of garlic is promoted. I am not disputing your warning, but rather, would like to know the source of your info so I can further my learning. Aside from the web, the books I have and reference often are:
*Natural Nutrition for Dog and Cats, by Kymythy R. Schultze.
*The Veterinarians' Guide to Natural Remedies for Dogs, by Martin Zucker.
*The Nature of Animal Healing, by Martin Goldstein.
* Holistic Guide for a Healthy Dog, by Wendy Volhard & Kerry Brown.

We lost our long time best friend of 12 years after he went on arthritis medicine. His symptoms were the same as the shots. lethargic and lost the use of his hind legs. Our baby, Duke was a large loveable husky who could jump a 6 ft fence.... when we saw what happened to him at the end of his life we swore we would never let that happen again to one of our family members. So now we have Pearl our 10 yr old chihuahua who has a heart murmur. We were told she needed her distemper vaccination. Needless to say we are not. If your furry friends are not out and around other dogs.. then love them with all your heart and let them be. Peace and love

I would recommend doing a websearch with "vaccinosis". My dogs recently had rabie shots and it nearly killed one of them! I am using a homeopathic vet out of Arizona who is terrific. We put him on a homeopathic remedy and he is doing terrific! Another thing I did was to add ACV mixed with raw honey to his food. The change in this dog is amazing! All the best re your little companion.

Ugg I am so disgusted with these vets, they know damn well what they are doing. It's not possible to be a veterinarian and NOT know the truth about what these vaccines are doing. How Stupid of them to lose our trust. You would think in a bad economy especially that they would want to keep our business. I'll tell you one thing for sure they lost mine a long time ago when they vaccinated my cat without my consent. My cat was healthy for 11 yrs without any vaccinations and without any Vets. I took her to a vet at 11 yrs old and they vaccinated her and it's been all down hill from there. If they thought they were pulling a fast one on me by causing my cat to need long term veterinary care they were sure wrong. I Now Take Care of her myself and with a promise that for the remainder of her life no matter how short or long that may be it will be spent in the BEST CARE in the comfort of her own home and she will NEVER have to be in the presence of those monsters again!!!! (I never planned to be a vet but, hey I will learn whatever it freakin' takes to care for my animals myself, I am the only person who can be trusted to do so) It's a damn Shame!!!!

P.S. This is what can happen if you go to an emergency clinic in Ohio or in any state or country for that matter. It is sick. I am telling everyone Do your homework as best as you can before hand in case you do ever need to go to a vet. To think I went to this emergency clinic once.

Yes, this is quite normal. Many vaccines cause immune response, (that's why we give them.) Should not be a problem. Yet, there is a very small chance that the needle site gets infected. The thickened mass will take a few days to appear and will usually progress to look just like an infection. If the swelling occurred within 24 hours of the injection,'s quite typical. Bret

Feeding your cat Fanci Feast is counter acting your wish for natural remedies for that cat. The nutricion values and processed materials in this type of food would be like eating McDonald's everyday for a person. I honestly think the vaccination is the least of the problems causing the cat to be lethargic.

I learned of the availability of a rattlensake vaccination, so I had my three-year-old labrador retriever vaccinated, with the recommended booster. It's been a couple of months now, and the dog's tear glands have ceased to produce tears, and he now salivates excessively. We now have to administer eye drops several times a day. He has always been a very healthy dog with regular vet checks, up to date rabies, heart worm, etc. Has anyone heard of any connection between these symptoms and this vaccination. We can't come up with any other idea what might have caused this.

Four Chihuahua puppies were taken at age 9 weeks for vaccination no 1 and a large lump developed on their shoulders which soon subsided. Six days after the vaccine one puppy seemed slow and under the weather and the the following morning was found semi conscious in her bed. We could not bring her round, her little body arched in a seizure. We gave honey and kept her hydrated. We rang our homeopath and we tried several remedies and she showed some improvement and then one more remedy and she came round after 4 hours on and off and was walking about. The following day she had another seizure in the morning and we knew which remedy helped and she came round in 30 mins. A week later she had another and the same pill brought her round in minutes. It is now about 10 days since the last episode. We feel the vaccination combined with mum's milk drying up may have been responsible. After the first episode she had lost her appetite and needed lots of care. She is full of life and eating well again. We will not go for the next vaccination in case she is too small and too young.

Can you please let me know which homeopath medicine you gave. I am facing similar problem with my 4 months old Siberian Husky puppy. She has got seizure twice. First after three days of vaccination and then the second followed after 5 days(i.e. after 8 days of vaccination. Please help.

Three years ago, I took my 3-yr-old dachshund in for his vaccinations and grooming. He was actually going to be part of a TV commercial the next day. When I picked him up his eyes were watering and his face was swollen. They told me he had a reaction to his vaccines and they give him benadryl and a steroid shot. He was a little better by morning. The sad thing is after his vaccines he started to have monthly seisures! He had never had one before. And the look in his eyes changed.

Fast forward a few more years, when "Skipper" was six and he needed surgery to clean out his stomach after gettign into the trash and digesting too much junk. The vet said it was "not-uncommon" surgery and I would be find to take him home in the evening. He went on to say most dogs are back up walking around later that night. Well, that's not the case with "Skipper" - unfortunately, he had could barely move or keep his eyes opened. I let him rest and just stayed up with him. But by mid morning, he was gone. It was awful! I have had to say goodbye to pets before from old age and stayed with them when they were put to sleep, but I've not had to go through this. And I blame it all on the vaccines triggering the reaction, the seizures and thus, not having the strength he should have to go through a "routine" surgery!

I've since found out doxies are one of the breeds that has reactions to the vacccines. It's crazy we are insisting dogs get so many shots yearly - just to keep veterarians in business!

September 13, 2008 I took my airedale, Teddy, for a Bordatella at Petco in order to board him the following week. He received this vaccine about 6:00 p.m. And by 8:00 p.m. he suffered what appeared to be a seizure and died. There was no time to get him to the emergency vet (this occurred on a Saturday evening. ) It was overwhelmingly sad. I phoned the emergency vet to see if the Bordatella vaccine could have caused his death and they emphatically told me no way. I wonder to this day, if it was the cause as he was fine before that.

I have another airedale who turned 10 in October. He and Ted were best buddies.

My heart goes out to Rusty's mom and dad for their loss. After reading your article on vaccines I will certainly heed your warning about a blood test before vaccinating. Thank you for the info.

My black lab Brandy used to have small reactions after her vaccinations. She would have facial tremors and what may have been small seizures. We never made the connection until later. She also had developed a thyroid problem when she was about 6 years old. I took her to the vet for her yearly vaccines (as I thought every good pet owner should). When she was 13, she was given her yearly booster as well as rabies vaccine. Within a few weeks she began having seizures that we could not get under control, even with seizure medication. We lost her that year.

A few years earlier we had a cat that was given yearly vaccines. She developed an over-active thyroid, and despite having lost a lot of weight and not seeming to be in good health, the vet gave her a full set of vaccinations, plus Feline Leukemia. At the time, I thought all those vaccines were in the name of good health. Within a few weeks of getting those vaccinations, she stopped eating and we lost her.

I now have 2 dogs, 4 horses, and 3 cats that have been given minimal vaccinations. My new vet doesn't fight with me or try to convince me to vaccinate. I am convinced that I lost both my beloved Brandy and cat Barney to vaccinations! I suggest every pet owner read "The Nature of Animal Healing" by Martin Goldstein, DVM. Despite 2 degrees in Animal Science, it is this book that began me on my journey towards true animal health. My animals have benefitted greatly from the limited vaccines and home prepared diets! I hold my breath after each state required rabies vaccination, but hope their overall good health will help them through its trauma to their system!

Our Rottweiler went in for his 2nd series of shots and by the time we walked out and to the desk to pay the bill my pup released urine all over my son. When my son put him down he dropped w/no movement, he went into Anaphylactic shock. He was critical for over forty minutes then hours til we could see him and bring him home.

Three days later he was licking the area where they injucted the needle and w/i hours it was flesh. We rushed him into another vet for a 2nd opinion and yes, it was due to the Lepto vaccine. Sad thing is they admit that at least one dog per yr per vet witnesses a dogs death due to this vaccine. So, why is it still out there, why aren't we warned til after the fact, and who the heck is responsible for the damage? His leg will be scarred for the rest of his life, we had to hold off on training, puppy classes, puppy daycare. I'm out of a job due to the stress of not wanting to leave him alone knowing that he could have future health issues, Seizures and now he's afraid of people and I can't even socialize him.

Our 7 week old Great Pyrenees has been having seizures every 2 to 4 hours after getting vaccinations.

I had a litter of pups get their first vaccinations. Exactly three weeks later all of them had back to back seizures for 48 hours straight. Horrible seizures where they ran across the floor and would slam into the wall. It was terrifying. I looked it up and found that lepto will cause seizures 21 days after vaccination. Just like my pups. They had seizures for several years until we found out that fish oil would stop them. Within a few weeks of giving them fish oil daily the seizures became so mild that the pups would just shake. Eventually they stopped completely. My pups lived to 14 and 15 years old. They never got another vaccination after they were one!

My chihuahua was given her puppy vaccinations at 6 weeks and then the next one weeks later. After the second one, she went into shock and then came down with epilepsy, allergies to everything and other problems. I actually got my vet to tell me (since he wasn't the one who administered the shot) that all of this was due to the vaccination. She lived for 8 years, with a ton of problems and then we finally lost her to a massive seizure that ultimately took her ability to use her legs and then pick up her head. Vaccinosis is very real and any shots should not be done without a titer to see if they even need the shot.

I cannot say the dose or the name of the vaccine, but when I bought my puppy, a mutt of blue heeler, australian shepherd origin, the seller immediately gave her an 6-way shot. I was told by vet those are very bad and dangerous. I have had issues with my dog, she began having seizures, yeast infections in ears, she has runny nose but its also not clear. For life of me I cannot keep her at a healthy weight, she holds fat, but overall I have a feeling that shot caused these problems

I brought my Sheltie, Toby, into the vet for his first or second round of vaccinations. They administered a shot and I asked them what that was. (at this time I was very trusting of vets). They told me it was an 8 in 1 shot. I was upset that they gave him so much in one shot (rabies was included). They reassured me that it would be ok. By the time I got home with him (about 20 minutes later), he developed a "bump" on the end of his nose. I immediately took him back to the vet because I knew he was having a reaction. By the time I got him back to the vet, his whole face was swollen. About 3 months later, he developed more bumps on his nose which went away. About 3 months after that, he developed epilepsy. We did everything we could do for our Toby. We went the regular route with phenobarbital and bromide and the side effects were horrible. He was so drugged, he would just sit there with his tongue hanging out (he was around 2 by now). And, he still had seizures about every 45 days. I took him off everything and consulted with a homeopathic vet -(this vet used to be a regular vet, but switched). I found that I could treat him with homeopathic medicines and achieve the same results without the horrible side effects. We also put him on a raw diet consisting of salmon, lamb, veggies, brown rice, etc. He ate better than we did. To make a very long story short; Toby lived to be 4. He had seizures about every two weeks - very severe seizures. The homeopathic vet said he was the worst he had ever seen. I believe that Toby would not have lived as "long" as he did if we had not had him on his raw food diet. On April 24, 2009, he did not come out of a seizure. It was heart wrenching for all of us. I do not vaccinate my animals and I feed my two cats raw food diets. I blame his seizures on the vaccinations he received as a puppy (and my ignorance). Toby was a great dog and we miss him very much.
On a side note - one of my cats is 16 years old and has been on a raw food diet for 5 years. I put her on this diet after she was given 2 weeks to live (cancer). She recently had blood work done (just to check her out) and the vet said that she was very impressed with the blood work. She said she would be impressed if this blood work was from an 8 year old cat. Bottom line - no vaccinations and feed raw food. Good luck to everyone.

My pekingese pup is just barely six months old and received her corona virus vaccine and her lime vaccine this past Saturday, 01/23/10. This evening at 5pm my pup went into a seizure. I think the timing is pretty weird that now that this has happened. Is there any side effects and/or reasoning that now the seizures have begun. A lot like autism in childrens vaccines,,,is there a possiblity this is now happening to my puppy?

EC: There are a few other reader posts in this section linking vaccinations to their dog's seizures, unfortunately.
