My cat Pinot, 1.5. years old, had his immunizations yesterday and has been tired, lethargic and sore for 24 hours. I am quite surprised and disturbed by this as the vet never mentioned any weird side effects like this. Pinot had 3 shots: Rabies (3 yr), FVRCP, and Leukemia. I am not sure if the reaction was because he had all 3 at once or what. Any feedback is appreciated.

We have a Golden Retriever puppy, 11 weeks old. The breeder told us that when he received his 1st puppy shot, he had a "possible" reaction one day later. The pup was lethargic and wouldn't get up or walk. He was taken to the vet who was not sure what was wrong but put the pup on steroid medication. When we got him, he was a happy, healthy puppy with no problems that we could see. We told our vet and gave her the records from the breeder's vet. When it was time for our pup's 2nd shot ( DAPP-CV), we "pre-medicated him with Benadryl. He was fine until the 2nd day after the vaccination when he vomited, became lethargic and just very sick. The vet kept him and gave him IV hydration and medication for 2 days. We took him home today. He is alert and eating, but is unable to use his back legs and yelps when he is picked up. He is incontinent of urine and stool. So far we have spent $575 which wouldn't bother me at all if he was well now....he isn't. I can only pray he recovers. I will NOT let this beautiful pup have any more vaccines... EVER!!

I just found this site through a friend and am blown away by the number of reactions pets have had to vaccines. I too went through something. I currently have two cats who got their combo shots every year as recommended by the vet. One year after the shot one of my two cats (a black mix breed) retreated under a desk and stayed there for over a day not eating, drinking or using the litter box. Every time I even came within a few feet of the desk to talk to her she would growl, hiss and lunge out if I got too close. This was very uncharacteristic behaviour. It was the weekend so there was no vet to take her to immediately and resolved to take her on the Monday morning but by the Sunday evening she was sleeping under the desk. She accepted food and water I brought to her there and seemed exhausted. By Monday morning she was up and about and fairly normally though a little quieter and less playful than usual. She was like that for a couple of days before she started playing again. A few months later a friend in Nova Scotia got her black mix breed cat vaccinated and the cat deteriorated in a matter of days and died. Of course she believed it was the vaccines but her vet naturally said no. Since then I only do rabies vaccines every 3 years (much to my vet's chagrin) and have had no problems. I had no idea just how many people have gone through this and seeing all these stories has just validated my decision. Thank you to all who have submitted homeopathic suggestions such as Thuja and charcoal...something I plan to stock my medicine cabinet with me.

My pug Richie reacts badly to some shots... My dog had his first three shots at age 1. So weak the next morning I brought him back but it was wearing off. This last Thursday I brought him to the vets as required by state law for his yearly rabies shot injected into his left front quarter. Next day he walked very slowly.that night couldn't walk down the steps without being carried, now so sore he walks gingerly and is miserable.

I am very upset about this, last week at this time he was a lively happy dog.

Its no coincidence that this maybe very unnecessary.He's with me almost 24/7 and does not come into contact with dangerous or germy conditions.Humans are over medicated as well.

My 10wk old puppy got the parvo shot at 10am this morning. He threw up 4 times and would not drink any water. Whenever he would heave he would fall or almost fall over. I tried to hold him up. When he fell he couldn't pick himself back up. When I picked him back up on his feet he tried to jump around and play????????????

I took my 6yr. old Lhasa Poo (18 lbs.) for her annual examine and shots on Aug 10, 2009.. She received her 3 yr. rabies and DHLPPC. Her fecal and heart worm were normal. Within a week she started to itch and then vomit the same day. I was giving her Benadryl the first day thinking it was an allergy. Her tummy was very red and her genital area was thee times swollen. The next day still vomiting so I took her to the vet. Mattie received a famotidine injection, benadryl injection, cerenia injection for vomiting and a fluid therapy SQ. She was dehydrated. The next day she was worse. Still very dehydrated and now 4 days without water or food. Back again to the vet. She now had to endure 2 days of IV's. Won't bore you with the list of meds they gave her. But now Mattie has bleeding ulcers!!! They sent me home with 9 days of meds for her. Sucralfate and Metronidazole. I can still hear her little tummy making noises sometimes. Scares me to death because I was told this was the acidity eating away at her causing the ulcers.

I'd like to know if these meds will cure her or is she damaged for life?? How can we let this happen to our pets? I read these shots stay in their systems for 10 years so even if they didn't have a reaction last year, like mine, now we're doubling it all over again! I would like to be a part of any petition to stop these unnecessary shots.

Some people may have already lost their little ones to this because they didn't seek help quick enough or the cost was too high. It has already cost me $535.00. If your dog won't drink and their gums are pale get help immediately.

My 7 year old chihuahua had her 2nd rabies booster and other shots two months ago. Within two days of the shots, she had a raised warm area about 2" in diameter at the injection area in the middle of her back. She was also lethargic and overly sensitive to touch anywhere on her back. That continued for a week and then began to enlarge to a general swelling to the base of her tail 5" past the injection site. I thought it may be an infection and treated her with antibacterial salve, garlic oil and/or oregano oil for the next month and a half. The swelling went down after 5 weeks, but my dog started loosing hair at the site and a small scab appeared after 7 weeks. I thought we may be dealing with mange, but there is no evidence of mites in hair and skin scrapings. 8 weeks later, she has a hairless patch about 2" in diameter and slightly scabby skin that is peeling with loose hair. At this point, I don't know if antihistamines will work. I don't know what to try. Does anyone have a suggestion for what to do now? Ginger

Serious reaction from rabbies shots

Pfizer-Schering-Plough S610804b rabbies shot chihuahua 5 pounds. Reaction dogs face very swellen @ muszzle, ftting, extreme movements on muscles. This was the second time the doctor knew he was allergic to 3 years vac. Gave me no report. I just found out information about these symptoms could be fatal. March 11 2008. Returned to Vet and he did not tell me anything he did. Dog until today has muscular movents in neck and missing leg (he never had problems in his missing leg).

Had the same problem, more or less 2004 end up on Emergency Room they gave 0.25ml nadexP04/0.4mlPred ACETME/0.1 CIMTIDINE. That is what is writting on the Emergency report, I was not told about that was a serious reaction that could let to death. Was told it was a normal allergic reaction. This vet did not gave me a report, my husband took her to court but was never brought the serious damage to the dog.

cat ill after vaccination... my beautiful 6 mo. old female kitty went to the vet for booster shots. she was somewhat sick after her first round of shots 1 1/2 months ago. this time she received a rabies 3 yr. booster and another shot, which was feline leukemia and "FVRCP" second vaccination. 2 shots total. within an hour of getting home she was spitting up a lot. nothing in her stomach, so it was just spit up. then came diarrhea! you could tell she was really sick. that was yesterday, today she's a little better. i am considering not getting any more shots ever for my kitty - i don't know why it makes her so sick, and i don't want to go though it again...

vaccination and IMHA: I have a Shih-zhu and she nearly died after getting excessive amounts of vaccinations from my previous vet. After getting a blood transfusion and multiple immunosuppresant drugs, she's on the road for recovery. I have been informed by my new vet that half of her vaccinations were unnecessary and posed her to the life threatening Immune Mediated Hemolytic Anemia.

My two-year old, 8 pound pomeranian-chihuahua cross was given the standard DT4PPV (or whatever it is called) and rabies vaccines yesterday and she is now totally lethargic. She was fine until this evening. She hasn't eaten for at least 8 hours, has not been outside, and has spent most of the last 8 hours under the bed, which is a rarity. She also has excessive eye discharge and her breathing seems a bit labored and her heart rate is higher than normal. We are watching her closely and will take her to an emergency vet if anything changes. She did have about 2 ounces of water a while ago and perked up for a few minutes. I hope this helps. Mandatory vaccines are ridiculous. I will never have her vaccinated again. I would rather keep her away from other animals than put her through this again.

Hi,

I have a 3year female chihuahua. She was born in May 2009, her first jabs were in July that year and she had a mild reaction ... swelling of face and eyes. A year later, the same booster had a very severe reaction - withi the hour her whole body had huge bumps, het face was almost twice the size, and she could hardly open her eyes. I rushed her back to the vet and he injected het with ananti-inflammatory injection.

I am so worried, now its been 2 years since the last jab. The vet recommended she can miss a year.

I dont want to take any risks and wonddered if there are any altenatives to protect her against distemper, hepatitis, leptospirosis and parvovirus. OR is it possible to give half dose ?? Also, I am not sure if the pet insurance is still valid if she has not had the booster.

Please advice.

Thanks
Kiran
