Hi,

My 18 month old Doberman Pinscher received six vaccines from the vet (who was only supposed to give two). That was on November 10th, since then he's been having grand mal seizures sometimes more than one a day. He's also become more aggressive, backs away, and has constent relestness. We've been trying to treat him according to the treatment vaccinosis by Dr. Dodds. Basically, my dog now suffers from major illnesses that we still cant control, all caused by vaccines. Its heartbreaking to watch and financially draining, but we do everything we can for our loved friends. I just want to express my concern to others to only due what your pet needs for vaccines, not what most vets tell you they need. Do your research and save your pets life.

Puppy vaccine reaction

I have had several puppies die over the years after getting their 1st puppy vaccine at the age of 4- 6 weeks. I'm currently watching one (maltese) fade away as I type this. The breeds have been Maltese, cockers, shih tzu's and poodles.

Vaccination reaction

My 12 week old Jack Russell terrier puppy suffered a severe reaction to the 2nd booster vaccination. She weighs 3kg, and had Leptospirosis, and a combined Distemper, Hept, Parvo Parainflu vaccination. She had swollen eyes, severe itching, hives. The vets gave an anti-histimine but symptoms continued for 12 hours. Worried now that there may be other problems in the future.

Vaccination Reaction

My dogs were vaccinated for bortetella seven days ago, and have had chronic diarrhea ever since. The vet denies any connection between the vaccination and the diarrhea. The two dogs who were vaccinated (female Spitz mix age 6 and male Chihuahua mix age 7) began having diarrhea within approximately five hours of the vaccination. The one who was not vaccinated (male American Eskimo age 15) has no such issue. All three eat the same whole food made from scratch rotation diet they have been on since they were puppies.

This vet also refuses to sign a waiver exempting my 15 year old dog with a history of seizures that began after a rabies vaccination from the rabies vaccine. The seizures were eventually cured after three years of remedies including Taurine and raw proteins along with emergency measure like Valium.

Because the vet who originally vaccinated him also denies any connection between the seizures and the vaccines in the best interest of his practice, I cannot legally license my dog in the state of California without subjecting him to further risk.

Needless to say, I am not a big fan of vaccines or the government imposed "vaccinate your dog every year" policies.

Of course the Vets deny everything! So do Doctors regarding children...

My dog Tasha, a now 14.5 year old, 10 pound Shih Tzu, has had a reaction to her yearly shots since a puppy. After each vaccination she would be very quiet and whine like she was in pain when I picked her up all day long. I finally stopped getting her annual shots, except the rabies one required by law, with the 2005 checkup. According to a natural dog publication, dogs don't require annual shots after age ten anyway. By then, they have built up enough antibodies to fend off most ailments. Of course the vet tried to avoid this when I questioned him except to say that the vaccinations actually last 3 to 5 years. It seems we have been over vaccinating our pets for years. Perhaps that is why they have all of the ailments they do ie. kidney and liver problems, since everything is filtered through these organs and even cancer.


Bordetella

We just got our 5 year old min-pin (who had never before gotten) a bordetella vaccine. Since we are going to board our other dog and he needed the vaccine, we figured we should get both dogs the vaccine so that the min-pin did not catch kennel cough. They both got the vaccine over a week ago and i just noticed last night that our min-pin been swallowing hard over and over again. At first i thought that he had a dry throat because we have electric baseboard heat but today he started to cough a little. I'm thinking that he may have developed a slight case of kennel cough from the vaccine. That's the only thing that we can associate it with at this point. I'm contacting our vet tomorrow. Has anyone else seen the side effect of their dog swallowing hard frequently?

Yes, our shih tzu puppy had Bordetella shot last friday and we have noticed it being quiet and wretching for a few days, but was frightened tonight because she seemed to be convulsing fit like and then stopped.

Distemper Vaccine

Hi my name is Brittany. My dog Daisy, a German Shorthaired Pointer, was recently put to sleep because her blood wouldn't clot. She was 7 yrs. and she has received the distemper vaccine before. Let me tell you about what led to her peaceful sleep.

She recieved her shot on October 28, along with a few other shots. When she got home she had started to break out in hives. She has always been allergic to things before so my mom thought it was just her fleas. A vet had once told us that she was probably allergic to fleas. So my mom put frontline on her and called it good in hopes that she would stop itching. Later on the 29th my mom found a bag of dogfood that she had recieved for free because one of my other dogs was due to have puppies soon. So she mixed the dog food in Daisy's food. That night Daisy had Diarreah horribly and had an accident on the stairs. My dad found it at about 3 in the morning and cleaned it up. He doesn't know or remember if there was blood in it, but he believes there might have been a little bit. Then my dad decided it was the dog food that my mom had mixed in to her food so he began picking out all the mix-in, because she lost interest in eating. Then Nov. 22-25 while we were camping in Oregon. She began to bleed from the crevices of her lips. I tried to stop the bleeding, but i couldn't get it to stop. She at this time had pretty much stopped eating all together. She ate a little every once and a while, but not much. When we got home on the 25th I had woken up to take the puppy out potty and Daisy was sitting in the hall way staring at the wall and head hanging slightly. Normally when I walk by her she stands, but not this time she just sat there. I brushed it off, but was still worried. I took the puppy out and came back and she was still there so I coaxed her to get on my bed and sleep with me, but every time she layed down she groaned, like she was in pain in her abdomine. Later on the 26th while my family was getting ready for Thanksgiving Dinner, my dad went into my room to see Daisy. She was sitting on my bed the same way she had been when she was in the hallway. He just barely touched her head to pet her and she cried out and wimpered. My parents immediately took her to the vet, where they did a series of tests. They took her blood and tested it for everything. Platelets, iron, everything. They also scanned her for tumors. She had no tumors. But when they got her blood tests back they discovered that everything was normal except her platelets levels. An average amount is 400,000 low is 20,000 she had 16. (per Ml) The vet gave her a Chemo shot in hopes that her body would produce more platelets. We left her there over night and she got worse rapidly. On the 27th we called to check in on her and she had fallen far. They had taken blood from her jugular and it had not stopped bleeding. She began to bleed internally in 3 places. Her intestines, her jugular, and her brain. She had 5 seizures while she was in the vet. The suggested we put her to sleep and that is what we did.

I am so confused as to what led to her death and her sudden illness. I believe that it was the Distemper Vaccine but I cannot be sure. I just hope to warn other pet owners so they do not have to witness what I have recently witnessed my bestfriend go through. When she died I held her. The scary part was that she breathed after her heart stopped beating. Im a 17 yr old girl who just wants to know what killed her best friend. If you can help me that would be great. I have to know so I can let her go.

Two days ago, I had my cat's yearly vaccinations done for rabies and RCPCh FeLV. Until the moment of vaccination, she was very active, talkative, ate and drank normally, walked, ran and jumped often, played and was generally alert and completely healthy. After vaccination, she immediated became lethargic, stopped moving at all or moved slowly by limping low to the ground as if in pain and only over a short distance, would not eat, drink or relieve herself. Yesterday, 24 hours later, I returned her to the vet. She confirmed the cat had a fever and was swollen at the injection site "probably" as a reaction to vaccination. She put her on an intervenous solution for 20mn to hydrate her and gave her an anti-inflammatory shot saying she would immediately become herself again. Today, day 3 since vaccination, she is not herself, she is hardly better, still moving with difficulty and lethargic, eating and drinking very little and moving hardly ever. I was told to bring her back today if symptoms persisted. I will be doing so today. I am very bothered that this should occur. My cat is an indoor only cat with no other animals around, therefore not exposed to these diseases and I regret accepting the vets recomendation to vaccinate.

Lydie, this is why I do not do the vaccines any longer. All of my cats are indoor and my dog goes in the back yard and that's it. My little dog used to get sick for days from the vaccination and one of my cats would get sick for almost a week. So, no more. My dog is 11 years old. All of the bad stuff that we put in our pets is why they get cancer and everything else. Vets will say it is not, but it is. . . What else is a vet going to say?

We brought our two one year old cats into the vet for one year vaccinations, rabies and the flu/virus bundle almost two days ago. The cats are littermates and both female although one is about 9.5 lbs and the other is 7 lbs. The larger cat has responded fine with no side effects and is completely back to normal and in fine health. The smaller cat is not herself and has been quite lethargic over the past two days. She has gone from a playful cat that runs around and jumps and climbs to laying around, not running or jumping or "talking" and has taken some interest in a few toys, but has not run or jumped since these injections. I have read that cats can exhibit signs of sluggishness and lethargy for a day or two after injections, so I am hoping this is a matter of soreness of hind legs/trauma of going to vet (both are indoor cats) and maybe a bit of (a non life threatening) reaction to shots. I'll be honest, I have read the possible side effects of what these shots can do to animals and I'm worried. She has, it should be noted been eating and drinking and using the litter box.

Before we got these two kittens, our 3 year old cat came down with FIP which we believe was transmitted from exposure from the same vet clinic that we took our new cats to as the previous cat was also a perfectly healthy indoor cat. We don't want to go through this anguish of seeing an animal suffer again. She died what must have been an extremely painful death through this FIP, and anytime something happens to our other cat that stems from this vet, these feelings come back that something wrong is happening. Thanks for reading. I guess my question is is a 2 day reaction to these vaccinations commonplace?

We just had our 5 mo. old Choc.Point Siamese vaccinated for distemper/leukemia Fri. She has been laying around since, got up once to play briefly, and I don't thinks she has eaten or drunk, either. I am going to take her back to the vet Mon if this persists. My other Siamese is "sensitive" to shots and has to be re-treated and watched. Good-luck w/your kitty and I hope ours comes out of this. I am getting worried now.


Lemon, Colloidal Silver

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.

My pup Oliver received a Bortadella shot in May of this year. On July 2nd, I had to rush him to the emergency clinic as he was having a hard time standing up and walking. His PCV was 17. Long story short, he had developed Auto Immune Hemolytic Anemia. After two awful months of massive medications, blood transfusions, and weekly vet visits, extensive expense and awful heartache, we had to put him to sleep on September 8th as he had a serious relapse. I have read that vaccinations can cause a pet to get AIHA. This was the worst experience of my life. I miss my pup terribly and did everything I could for him. Did the vaccinations cause him to go into AIHA? I don't know, but it is a very good possibility after researching and communicating with others who are going through the same thing with their pet.

Vaccination death

Our baby, Tinker Bell was a six year old, almost 7 pound Chichawa. We took her in for her yearly vaccinations last week. Less than fifteen minutes later, she was dead. She had never experienced any problems with her shots before. Our vet said she had never seen a death as a result of the vaccinations, but she knew it was a risk. We didn't realize the risk involved. Thank you for your web site.

EC: We are so sorry for your loss.

I had my Shiba Inu, 12 years old, vaccinated with about his 10th lyme vaccination in June. About 48 hours later he began being lame on his right rear leg. The vet would not hear us out on it being due to the vaccination, but could not find any other reasons for the lameness. He has now progressed to not being able to walk on either hind leg. He "shuffles." Today at the vet the vet again could find nothing wrong and sent us on our way. They were quite offended that I think it could or might have something to do with the vaccine. They actually told me I could just get a copy of my dog's file and go elsewhere. I have gotten the copy. How rude of them, this dog has been there for 12 years and I had other pets there for over 25 years. I was given an antiinflammatory and sent on my way.
