Please let us know about any side effects you have witnessed after your pet's vaccination or booster shot. We'd like to know the name of the breed of your pet and also which vaccinations he or she received. Did your annual dog vaccinations include the rabies vaccine? Was it a combination vaccine addressing several potential dog ailments? Did you opt to give your pet cat vaccinations? All the details are important.
As we gather more information around this subject, we can better assess whether first-time vaccinations or follow-up booster shots are responsible for causing deadly complications in certain breeds of dogs and cats.
If your pet has experienced side effects from a medication like ketoconazole (for yeast skin infections), we have a new page on pet medication side effects here.
As of September 4, 2013 over 344 people have reported side effects and over 40 people have reported deaths from pet vaccinations. See their feedback in our table of contents menu entitled "Vaccination Reader Feedback".

[YEA] I have a 6 year old Rat Terrier. After recieving her yearly rabies vaccination booster she started having adverse reactions to it. It started with a lot of scratching, and with in a few days to a week a small bald spot appeared with a small lump under the skin, about the size of a quarter. I have had a few friends whose dogs have completely lost all of their hair and regularly have scabs or sores where they recieved their injection, so I knew right away what it was. I as soon as I noticed the missing hair and felt the lump, I took her into the bathroom and washed her from head to paws with a medicated shampoo to rid her skin of any bacteria, dirt, or possible allergins. To prevent her from scratching I spray the area with a cortizone several times during the day, (this is something you can buy at the local pet store) and stop her from messing with it anytime I notice. On days that the itching seems more severe I give her a 25mg benadryl tablet and it does what I need it to do. When I think about it, I gently roll the lump between my index finger and thumb, and I also "snap" the skin a few times by pulling the lump away from her body and allowing it to snap back. This increases blood flow to the area and helps the body deal with the issue. I do these things just a few times, so I dont aggravate her or the area. So far the lump hasnt gotten any bigger, and the hair loss is only localized to that one little spot. I am happy with the results I have seen in her, the lump still isnt completly gone, but its doing much better. Her hair hasnt started to grow back either, but I figure a quarter size bald spot is better than no hair at all. I still continue to bathe her several times a week, but now I am using a oatmeal based wash. It much easier on her skin than continually using a medicated shampoo, and it seems to help with the all over itching as well. I wish you all the best of luck if you run into the same issue. I'd reccomend taking you dog to the vet if the lump continues to get bigger, if your dog gets hives, a temerature, or starts losing hair all over. I have a friend who has a toy Chiuaua and he had a severe reaction. She waited too long and didnt treat him herself so now he has open sores regularly and is hairless. By the time she got him to the vet there wasnt much the vet could do for him. They gave him a cortizone shot and some benadryl... two things anyone can do at home. I hope this helps some one, and once again good luck!!

I have had a total of four dogs in my lifetime, two of them had reactions to vaccinations. My first dog was a male pug and had skin allergies. After vaccines, large tumors came up on his skin and there was a very strong smell that never went away. He always smelled but this was alot stronger. I now know that this permanent smell was the liver being unable to detox the vaccines and not due to the lack of bathing. The dog had to be on pregnisone the entire time, without it he would scratch and scratch until there was blood everywhere. I stayed up many nights putting him in a bath of greenzone which helped but didnt cure. I now know that his liver needed some work. He died at the age of two, from a stroke. I cant say it was directly from the vaccines but I can say that he got alot of help from the vaccines and the pregnisone. My other dog was a German Shephard, I inherited him from the neighbor that severly neglected him, she did tell me that he had heartworms, but she didnt tell me about the seizures. I questioned her about his first seizure and she doged the question, but after having many seizures, she finally admitted that his first seizure took place after he was vaccinated and was given heartworm meds. Imagine that, giving a dog with heartworms vaccines. Well that would explain his second seizure that came after the second heartworm treatment. This was a grand mal seizure and I thought that was it, but the doctor gave him a shot of steriods and it revived him. It lasted maybe a week and a half, then I gave him oral steriods every other day and then He had another seizure, but it wasnt bad. Then he got a severe infestation of round worms. I dreaded getting the meds, because I knew what was coming. I had 3 seizures, one every day. By that time, I knew this dog could no longer take any meds at all, I also knew that he couldnt handle chemicals either. But I wasnt able to put it all together fast enough. He started to decline, took him to holistic vet, she gave him an eye exam and from the look on her face I knew that this was a brain tumor. We were able to stop seizures, but not the brain tumor, I had to put him down yesterday. I now know that holistic doctors can detox these vaccines out of their systems.
As for heartworm, the meds are nasty but so is the disease. They provide heartworm nosodes that works for some animals but not all. I will spray my other two dogs with natural mosquito repellent instead of giving heartworm, which I have never done with my own dogs but after what happened to Obie, I am taking this disease far more serious. So what happened, I now know that obies liver could not detox and that all the toxins were routed to his brain which in his paticular case was the weakest organ. Toxins generally land on the weakest organs, then you have parasites, fungus, yeast, bacteria. Much like you would see with rotting garbage. Of course, I was not giving the whole truth about obies condition from the start. According to New York Times, one rabie shot should last a lifetime. My philosphy is after these experiences is one set of shots and one rabie, if you have an outdoor dog. MY new pug has hever had one, there are no racoons in my living room, at least I hope not. As for a large dog, that is more tricky, if they bite someone, and there not up to date on rabie, owner could be sued. If you want a healthy pet, stay away from the vet unless it is an emergency. Stay away from corn, diary, gluton and soy, no chemicals at all, supplements also have fillers and binders that dont set well. These expensive vet supplements have them too. There are supplements that are O, K. If you decide to vaccinate, call a holistic vet first, be ready in case you have a reaction to the shot. Most of all old dogs should die from old age, not from heartworm, tumors, seizures etc. Those were the excuses from the previous owner. Her excuse was, he was just an old dog, and she couldnt wait to put him down, as she had been trying for the past year. Each time we blocked it. It was just too inconvient and embarrassing for her. This is still too raw.sorry
[YEA] We adopted a 6 week old chihuahua, Max(his mom is a rescued miniature chihuahua, father is not known). Max weighs about 2 pounds. His first vaccination was given between 6 and 7 weeks. A friend gave him the 7 in 1 vaccine. After about 4 hours, I noticed swelling on Max's whole neck, and it was very tender (no swelling around his throat). Called a friend who works with a vet, she said to give him children's Diphenhydramine, but wasn't sure of the dosage. I gave Max 1/2 ml of liquid Diphenhydramine, repeated the 1/2 ml dose 3 hours later. I gave him another 1/2 ml dose 4 hours after the 2nd dose. By this time the swelling had gone down some, he seemed to feel better, but I just wanted to be sure he was going to be ok. By morning, the swelling was gone, he still has a little bump where the injection was done, but other than that, he seems fine.
EC: Another name for Children's Diphenhydramine is Children's Benadryl.
[YEA] 15 years ago and before I thought I was being the good pet owner and getting my dog, a mix Golden X,vaccinations whenever they were needed. Long story short, my dog acquired mast cell cancer from vaccinosis and it developed at the injection site. I did enlist a holistic vet after his vet said he only had 3 months to live. Going totally holistic with treatments, my dog lived a good quality life for 2.5 years thereafter.
I now have 2 Old English Sheepdogs who are naturally reared. They are 9 & 10 currently and have had no chemicals in or on them, are fed a raw diet and have only been to a vet once. They had their puppy shots and that was it until my one dog was diagnosed with a hernia. He had to have an operation and they wouldn't do it until he had a rabies shot. This would be his second in his lifetime. I was reluctant but knew he needed a repair of his hernia. 2 months after that shot, he developed cysts all around his neck area. Sheepdogs are extremely sensitive to shots of any kind and he did puff up at the injection site. I was told by an herbalist to take a slice of lemon and rub it on the site and the puffiness went away. I then began using Colloidal Silver in drops 2x a day on the cysts and in a matter of a week, they burst and were gone and have never returned. They will never get a rabies shot for the life of them. My dogs have never had medications either of any kind. I treat them homeopathically and herbally and they are thriving.
EC: Thank you, Carol! Your feedback has been cross-posted to the Side Effects section on the same page.

|BETTER BUT NOT CURED (1)||100%|
[BETTER BUT NOT CURED] My 21 mo old 6 lb Female Papillon developed allergy symptoms, gastric problems, and some nervous, paranoid and insecure behavior soon after receiving a SQ rabies vaccine in her right shoulder. Symptoms were mild to begin with but worsened over the next several weeks. We initially treated with Children's Benadryl 12 mg orally TID. 5 weeks after being vaccinated, at the vaccine site she developed a large area of alopecia (2" wide by 3" long and appears to still be increasing in size) which is quite large for such a small dog. We started treating with Temeril-P 1 Tab BID and decreasing dose. She's near completion with her with the Temeril-P and has just started Pentoxifylline therapy o.25 ml BID (120 mg/ml). My Vet had it compounded into a liquid, due to the fact that it only comes in a non dividable time released coated caplet at the pharmacies. The gastric upset and itching has improved, though she is still foot licking and face rubbing. This is an extremely beautiful, well bred show dog, and beloved friend. I'm concerned about long term effects, and of the alopecia increasing in area and possibly affecting her beautiful ears and face. Anything more I can do to help insure she recovers completely?

I have 3 little dogs which will have to have a TOTALLY unnecessary Rabies shot before they will be allowed back into Australia. They had a Rabies shot last year in October and will have to have another as AQIS (Australian Quarantine) demands that the shot be within ONE year of them entering Australia.
I am VERY concerned the effect this will have as 2 of them are elderly.
WHERE can I get Lyssin and/or Thuja ? I am not getting very far searching through Google for homeopaths. I found an online company which will make up a remedy for $45 EACH!!!!
[BETTER BUT NOT CURED] Allergic Skin reaction as a result of C4 vaccine in dogs :
I have recently got a puppy at 8 weeks old, wo had his first combination vaccine at age 7 weeks, distemper, parvo and hepatitis. As someone who didn't want to expose my puppy to unneccesary vaccines, I chose to only give 1 more vaccine at 12 weeks. 10 days later my puppy broke out in a rash with his hair sticking up causing little bumps all over his back. He is on a fully natural raw diet, has had no contact to any new plants or allergens that I can think of, and I believe the vaccine has caused his immune system to weaken. I gave him a remedy of Thuja, as well as Apis to relieve the itching, which seemed to help. The following day I also gave an activated charcoal tablet and sprayed ACV on his skin. Within 5 days I saw a noticable improvement. I continued the same diet, also adding in ACV, flaxseed oil, garlic and kelp. 2 weeks later he had another itchy rash come up, this time starting on his belly and sides, seemingly effecting the parts of his skin where it had previously not been. I have succesfully treated the very red raw rash on his belly with the same treatments as above, but am still battling the remaining parts on his sides which he keeps itching. I am convinced this is a result of the vaccine and I hope to build his immune system to overcome these reactions and never vaccinate him again. Just in case this may help anyone with similar problems.

Pet & Human Vaccinations: I was doing research for alternatives to vaccinating my son and found many vets using Nosodes instead of traditional vaccinations. Here is a quickie Wikipedia explanation of Nosodes:
"Nosodes are homeopathic remedies that are made from the specific products of a particular disease. This can be tissue containing the actual disease agents or tissue affected by those agents. Sometimes nosodes are made from vaccines containing the organisms. The nosodes are prepared in a diluted and potentized form just like all other homeopathic medicine. There is no potential for an animal to become infected with a given disease agent from a nosode because of the pharmaceutical process that occurs which dilutes and inactivates any viable organisms."
Anyhow, I continued my search to see if they can be used on people as well and found a local doctor who prepared all of the vaccinations my son needs. If you are looking for an alternative for your pet or baby, check out Nosodes.

[DEATH REPORTED] My cat has a death sentence today because of a cancer caused by vaccinations called fibroscarcoma...i have had this cat when he was a kitten 1 month and had him for 9 years this month...he was limping and had a lump on his shoulder..it went a way but then it came back with a force. It was small and not it is as big as the palm of my hand...he cant walk he eats very little...and I am devastated by this mess...and somebody needs to be responsible for doing this to this cat...getting all these shots for nothing rabies/FIV/FLiv/ and kitten shots fine but not every single month even my new vet doctor said u dont need every year shots especially if he is a indooor cat...every 3 years most if any does he need any shots especially if he is an indoor cat...! The pet food is crap with all the dead animals in the food when these shelters kill animals...with all the additives that will kill these pets and addition heartworm medicine such as revelution medication for fleas/ticks/heartworm med...hum if you get heartworm they are done. There is no cure!!!!!!!!!!!!!!!!!! As well having the shots for your cat and heartworm medication revelutions together is a deadly for any animals dog/puppy or cat/kitten....do your homework, it is vital DO NOT GIVE SHOTS ALL AT ONCE TO YOUR PET DOG OR CAT...ONE AT A TIME IF THEY NEED IT...DOG & CATS ARE VERY DIFFERENT! Do your homework...do not rely on what they tell you; they are all in it for the money!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
[SIDE EFFECTS] My Chorkie had a horrible reaction to his Rabies/portadello...almost lost him! Living 5 miles from the vet I was just blocks from our home when max started FLIPPING all over the floor of the car. My first reaction was that his harness was pinching him. I pulled over, removed the harness, and at that time he started struggling with his breathing... His tongue was hanging out and he just went limp. I ran into the house (carrying this little 6 lb. Dog who is having a hard time breathing) called the vet and they told me to get him back out there quickly! Now his face is swelling and he is really gasping for air as we get back to the vets. They gave him a pill because they were afraid to give him another shot! I've never gone back for is booster.
Because of the "Law" I am being forced to give my dog a rabies shot. I have been working with a homeopathic woman to help my Lab get better. Most of her problems are from over medication and vaccination. The homeopathic woman said that if I get my dog a rabies shot she will not work with me anymore and the dog will backslide. I just feel trapped between a rock and a hard place. Does anyone know of anything homeopathic or otherwise that I can give my dog to counteract the rabies shot?

Earth clinic readers with pets I need your HELP!!! My 8mth old chihuahua nipped someone who approached our house, and she complained to the authorities and he didn't have a rabies shot!! We were not planning on giving him one do to the horrors I have read about what they can do to destroy a dogs health. But now because of the complaint (and she wasn't hurt either) we are forced to. I can't even imagine letting someone put those horrible toxins and the RABIES VIRUS into my little puppy who is so healthy. Even here on EC I read about the health problems that quickly arise after the rabies shot!! He's SO healthy and I'm worried!! Can anyone out there recommend something I can give him to help prevent and reverse the damage to his immune system that WILL occur (even if not noticeable from the outside)after the poisonous shot??? Is there something I can do before?? His shot will be on the 5th of sept. Thanks, Mama

I have a English Staffordshire Bull Terrier that has had two petit mal seizures that I know of. He has had his yearly booster shots every year and he is 5 years old. Should I stop the booster shots and I also give him "Advocate" for flea tick and heartworm or should I stop this as well. He had a blood test done when he had his first seizure and the vet said everything is fine. I feed him home cooked meals (kangaroo meat with pasta and green peas) and dry food "Holistic Select Dog Food - Duck Meal & Oatmeal Formula" any advice would be appreicated. Thank You for your time.
[SIDE EFFECTS] I bought a rescue puppy at 4 months of age. When I bought her, she seemed perfectly healthy. Stools were normal - she had energy and seemed very healthy. I took her to the vet for her check up and to clear her for any issues. She had a small ear infection which was cleared up easily enough with an ear cleaning and drops, and the vet recommended I give her Lyme vaccination. I was reluctant, but the vet convinced me it was necessary. So, she got her Lyme vaccine. I was due to go in a week later for her 5 in 1 vaccine which included Parvo. I saw another vet that day due to the one who originally gave her the vaccinations not being available. He gave her the 5 in 1 vaccine, and he injected her with ANOTHER Lyme vaccine. He told me it was Lyme as he was injecting her. I told him that she already had her Lyme vaccine last week and she wasn't due for her second for 2 more weeks. He looked perplexed, pulled the needle out, and didn't charge me for the vaccine. He didn't even put it on the bill that he GAVE her any Lyme vaccine. The very next day, my dog had terrible mucus filled diarrhea. HORRIBLE. She became dehydrated, despite me giving her water orally via a syringe, and so 2 days later I took her back to the vet. They gave me a prescription for the possibility of worms even though her feces showed no worms, and gave my antibiotics in case she had an infection in her intestines. Her poo got better. Markedly better. Normal! I felt much better. 4 days ago, her prescription ran its course. 3 days ago, her poo was fine. 2 days ago, it started getting softer, but still formed a normal shape. Yesterday, it was extremely soft. Pudding like. I began feeding her a bland diet, and added a little canned pumpkin in there for added fiber. Last night, her feces were extremely soft, and I knew I was in for a sleepless night. I was up almost all night with her, taking her out several times to poo. Her poo got much worse throughout the night until around 5am it was total mush. She is once again quiet, and I am force feeding her water. I made an appointment with the vet and her appointment is at 3:40pm. Although, I'm taking her to the same vet office I believe made her sick in the first place. I'm seriously considering taking her somewhere different. What should I do?? I really need help to make my puppy healthy, but I feel lost as there is no diagnoses for her issues, at least thus far.

I own and run an extremely successful hydrotherapy pool for dogs. This means over the period of 14 years I have treated thousands of dogs. Very many, including my previous dog, Monty, have suffered many and numerous side effects from over vaccination. These range from weakness in legs, auto-immune diseases, such as arthritis, skin complaints with rashes and skin turning black, hot spots, hair loss, nerve damage and brain damage. I, amongst, a growing number, including a long list of alternative vets in England, believe dogs do not need vaccines throughout their lives. When I realised my beloved Monty was vaccine damaged, I had teeter tests performed, this shows the anti bodies in the dogs blood. Every year Monty had high levels of resistance to parvo, distemper, para-influenza & distemper. The test does not show lepto. I believe you should wait till puppy is 12 weeks, so the immune system is better able to cope, before giving vaccines and after the initial 2 sets, 2 weeks apart, then they are protected for life. No flea or tick treatments either they are another form of toxins our dogs systems can do without. Go with your instinct on all matters concerning your dog and remember to question always. . . Whose interest is it in. . Your dogs or your vets.
