Per your request for info re animal vaccination reactions:

My DSH [domestic short-hair feline, a b/w tuxedo female, age approx. 15 yrs. , had her first negative reaction to a vaccination. A distemper booster turned the white skin on the back of her neck black. Nothing further happened, and that condition dissipated; however, that small section is now bald. Her vet, who is very good, was alarmed by this result and checked with the manufacturer - which claimed no other such reactions. The vet entered into my cat's files: NEVER EVER AGAIN GIVE THIS CAT A DISTEMPER SHOT. FYI. Thank you for this forum.

This past April we took our two cats into our new vet to get their distemper shots done. This new vet required us to get those shots for our pets to be seen by them. For the whole time I've had my cats, one for 14 years and one for 7 years they have only ever recieved their distemper shot, not the rabies vacination. So we took our cats in for their shots and there was a BIG mis-communication between us and our vet. When the vet came into give the shots they gave our cats both the rabies and distemper shot. I honestly didn't think to ask why they had two needles. I know this was a big mistake on my part and it was our fault for not saying anything or asking why two needles. So after the shots when we paid we realized that we paid for rabies shots. I was very suprised and said to my husband that well it can't hurt them but next time we won't get those for them since we never had before. Well a week after the vacinations were given our younger cat who is 7 years old came down with a Urinary Tract Infection/UTI. He had never had a UTI ever in his whole life until a week after the vacination. My husband and I immediately both thought that it was related to the rabies shot since he had never had one before and now all of the sudden a UTI! So we took him in to be treated and I asked the vet could it be related to the rabies shot. Well naturally the vet said no, that it would have nothing to do with it. But then why would they say anything different? They make money off of it! Both of our cats are indoor cats, and have been their whole lives so this is why we don't get their rabies shots. I will not be so irresponsiable again when it comes to vacinations for my pets. I personally feel it was because of the rabies shot but who knows. I know my pets and I take very good care of them so I personally feel that the UTI was caused by the rabies vacination.

My cat got his first distemper vaccine yesterday at the ripe old age of 3. He's been acting like he can't even hear me like he's mad at me, because I call his name and he is unresponsive, very lethargic, sick to his stomach, walking very slowly, having a hard time jumping up in places where he has never had any problem before, and all he wants to do is sleep. He is a very vocal cat and he hasn't made a sound since we came home from the vets office. He is also very cautious with where the injection was given, he seems sore in that place. If you have any idea if this is from the distemper or rabies shot or from something else please let me know because my cat is one of my best friends to me, because he is always there, and never judges you haha =] thank you.

I had a 4 month old kitten die of cat distemper because I didn't get it's vaccines. I think that telling people not to get vaccines is wrong - it was the death of my little Angel.

My cat went in for her distemper shots yesterday afternoon. She was eleven weeks old. Today, the vet called us to see how she was. She would not walk, eat, or drink, and she could not stand up. She had to go to the emergency vet and went into cardiac arrest. The first vet told us that there was no possible way that it was an allergic reaction but the emergency vet said that it was very possible. I have never heard of a vet calling to check up on an animal. The kitten has died now, but it is still weird that no one can seem to find a reason for the sickness.

Mike, I'm so sorry for your loss and have a similar story. They gave my 15 year old female cat a distemper shot and within 1 week, she became totally lethargic, wasn't eating or drinking and at the end of the week could not walk. They put her on steroids and I have to say they did help her but I don't want her to have to be on steroids the rest of her life. I found a holistic vet and she is doing accupucture and chirocpractic treatments on her. She was doing better for a while but mentally, she's just not the same and I'm afraid she never will be. She was 15 and extremely healthy. She was still a bit playful, had bright, shining eyes, ran, jumped, and played hide-and-seek with me. Now she lays around all day and night and basically only gets up to eat and barely eats at that. I miss her so much and could just cry every time I see her. I feel like I poisoned her and it's taking its toll on me.

I've since found out that the vaccines they are giving our pets (and children) have mercury in them -- the worst toxin on our planet and they are shooting it right into their bloodstream -- and telling us they need it. And why do they use mercury in our vaccines -- because it increases the shelf life.

They over vaccinate under the guise that it's necessary and I've since found out it's not. After a certain age, they just don't need it anymore and in fact, it builds up in their system and actually can hurt them.

re: Distemper Vaccinations: One of my kittens [10 weeks] is having some sort of reaction to a distemper shot. He is very drousy, doesn't want to move, and has a sore abdomen. He mews when you touch a spot on his back & pick him up. He also will not purr and looks very uncomfortable. My other kitten who received the same shot has no visible side effects & is her usual energetic self. I'm really worried about my little boy kitten, he isn't acting normal. Please let me know if you know what's happening to him & how it can be fixed!!

I'm a Pet Rescuer and over the years I have witnessed my own dog have reaction to rabies shot:developed lump on right side and aggression, called to report it but told me that the days from shot was over the course to report. Next, a lost german shepherd was lost;took her in got her spayed and received the distemper shot;her behavior changed to becoming aggressive and now I'm having problems handling her. Before the distemper shot, she knew basic commands and had no problem handling her at all. I don't know what happened to her and why such aggression.

Hello Sofia,

Two thoughts come to mind when I read your post: homeopathic [pill form] thuja occidentalis may help with to detox from the vaccinations. You might also consider adding bentonite clay or activated charcoal to your dog's chow for 2-3 weeks for internal cleansing as well.

And about your shepherd's aggression; the distemper vaccine is not known for having that side effect - rabies, yes, but not distemper. It makes me think something else is up, such as hypothyroid. There is a link between low thyroid and aggression/compromised mental state, so my advice to you would be to have a thyroid panel run on your shepherd to see if the thyroid is functioning normally.

In my book on homeopathic medicine for pets, Dr. Don Hamilton DVM, relates that since the high use of rabies shots, aggression is the result and it is also the most injurious injection of all of them. He says that multiple problems arise from vaccinations per se. It is a shame to torture our pets for what is obviously 'business".

So Sorry Namaste, Om

Okay, I have to tell our story of our beloved lab named Mo. We took him for his distemper shot and he got so sick from it. He could not walk or eat. He was vomiting and jerking. We called the vet and he said he must be allergic to the shot. So we said please make sure that it is on his record for future shots. It took almost 2 weeks before he was better, but he was still acting a little strange. He would take off on us (we live in the country) which he NEVER did before. There is a campground about a quarter of a mile away and he ended up there and they called the Humane society to pick him up. We called over there and they said they had him and they were getting his vet record. We said he was current on all shots which the record would show and we would be over to pick him up. They said we had to pick him up before a half an hour or it was an "extra" charge after noon. We got there before noon and they had given him ANOTHER distemper shot EVEN though they had his record and it showed he was allergic and current and that would be $90 please! What? you have his record and it says he's allergic and you gave it to him anyway? He was so sick, he went blind. We took him for emergency vet visit and they said he had brain cancer. Well if he did it was from the freaking shot! Some "humane" society!! They killed our dog-period and I will never forgive them. He was a happy vibrant just fine dog before those two shots! There is nothing "humane" about giving a dog a shot he didn't need and already had when it clearly showed on the vet report he was allergic to it for a stinking $90!

My dog died recently. We had to put her to sleep. I know it had to be from the distemper shot. I am going to say something to the vet this week. I would like the name of the company that the vaccine came from. I want to contact them. Dogs and cats are being vaccinated too much. I am going to pursue this so my little dog did not die in vain. I think you should do the same. We have to do something. These companies and the vets are making loads of money and putting our precious pets in jeopardy.

My 11 1/2 year old springer spaniel, Abby, had a distemper shot on Oct. 13, 2011 and we had to put her to sleep on Nov. 1. I think it is from the shot. We took her and my other dog, an irish setter named Butch, to the vet for their shots. Also, my irish setter had enlarged lymph nodes. At the vet he didn't get the shot but had other tests. She had a slight limp from jumping off our deck. But 12 days after the shot her limp go really bad and her face got droopy. We took her back to vet and she said her shoulder showed atrophy and she had bell's palsy. She gave us something for the shoulder and gel for her eye on the bell's palsy side. That was a friday. Over the weekend she got worse. On Monday she couldn't walk. Her back legs gave out. We took her back to vet and they kept her overnight. The next day she couldn't move from the neck down. They had given her steroids. She had to be put to sleep. It was heartbreaking. I love her and miss her so much. She did have some arthritis issues but no like that. The other dog that was diagnosed with lymphoma is still around taking medication. I think this all was from the distemper shot.

I took my 2 year old perfectly healthy pomeranian in for a routine vaccination this past saturday. 3 hours after he recieved his distemper vaccine his left leg went lame. I brough him to the ER, they gave him benadryl and steroids and kept him for a few hours, I called to check on him and was told his right leg went lame as well. He now is paralyzed from the waist down and cannot control his legs or bladder. I moved him from one ER to the next to try to get some answers--no one believed me that it was from the vaccine.

They insisted that he must have a disc or spinal cord injury. They did a CT scan and an MRI--no disc problem was present. They found that his spinal cord was dying off rapidly. They are monitoring him now hoping that it will not travel up his spinal cord. They want to do a spinal sugery but I will not let them because I know in my heart my dog was not injured. It has to be a side effect of either the vaccine or the needle. Does anyone have any insight?? I am truly devastated. I have already spent $6k and no results. I will try anything for him. Please pray for my little Carlos and send any helpful information my way!!!

See a homeopathic vet right away!!! Thuja is supposed to help with reactions to vaccines. I'm sure they have more helpful remedies. Also one that knows animal acupuncture. Good luck!!!!

My Pekingnese died in four days from a distemper vaccination. He was in otherwise perfect health. The vet who had administered the shot admitted that it sometimes happens. I had never heard of a deadly reaction to a shot that we are told all dogs must have. Her sanguine advice was, if I get another dog, to "get the dog's titres checked" before getting the dog vaccinated for distemper.

Yes, I Have had a GR puppy that had frequent and excessive urination right after I vaccinated him with distemper shots. Never again. It took a long time for the issue to correct itself. A good Holistic Vet can give your dog homeopathic treatments that has no side effects and may help your pup get back to normal.

My two year old Havanese had a very bad reaction to the distemper vaccine. She had this vaccine alone without any other vaccine's at the same time. I will never get my dog vaccinated again (except for rabies.. State law every 3 years) but I will get Titer tests to see if the dog is protected against these diseases properly. Vaccinations are very scary!
