My 10 year old beagle Annie had her bordetella vaccine on 9/6/15. The next day she became gravely ill. She seemed to be in severe pain and would flinch when you tried to touch her, especially around the head. I rushed her to our vet and spent 2 days in the hospital. She was sent home with prednisone and antibiotics. She seemed to slowly be getting better until 3 weeks later when Annie developed a severe eye infection. Our vet referred us to a pet eyecare specialist and he concluded it was caused by nerve damage on the left side of her head. Annie was happy and healthy prior to the vaccine.

(HERE IS THE KICKER) our vet contacted the manufacturer or the vaccine and they replied that they have never heard of any problems with the vaccine. Then our vet said they are going to send us a check for 1,300.00 dollars.and they did. Something is very rotten in Denmark. Something must be done about this.

Please help me... my perfectly healthy 6 year old Tibetan terrier had his bordetella shot in April and has not been the same. He has seen 2 vets, many tests, xrays, ultra sounds, blood, stool and all have come back negative.

He is anemic, lethargic, lost weight, and appetite. I did some research on this vaccine, and am frightened with what I am reading on the side effects.

Please guide me as to how I should approach this horrible situation.

Thank you in advance,

Hey Dale!

Did your vet check for Immune mediated hemolytic anemia? This is one documented vaccine side effect.

From the web:

"Immune mediated hemolytic anemia is a severe, life-threatening disease whereby theimmune system targets and destroys the red blood cells of the body, resulting in anemia, jaundice (yellow gums), pale gums, weakness and sometimes fever. Animals can be so severely anemic that they need blood transfusions to stay alive and some maydie as a result of anemia and lack of oxygen to tissues or as a result of blood clotsentering the lungs, brain or kidneys (ruptured red blood cell membranes float around causingclots to form). These animals are sometimes very sick and in need of special veterinary care and immune-suppressive medications in order to recover. Some willnot recover despite what we do.

When to worry:

Any dog with pale or yellow gums must be seen by a vet. These signs will often be accompanied by variable signs of lethargy (tiredness), low exercise tolerance, collapse, dark coloured urine (the urine is often deep yellow, red - the colour of port wine - or brown), heavy or rapid breathing and sometimes inappetence and fever."

About two months ago I went to get my jack Russell shots and vet said she needed the bordetella. I had no idea that I could refuse. My pup is never around many dogs and we don't do the dog parks. Now she reverse sneezes and at night while trying to sleep she has mucus in her nose and it's hard for her to breathe. This was never an issue before the nasal bordetella. I'm very angry. And I am saddened to hear that she never really needed it to begin with!!!!

Hey T!

I am sorry to hear about your JRT. The bordetaella [kennel cough] vaccine has been proven to not work AND your dog has been shedding live virus, potentially giving other dogs KC, for weeks now. The shedding of the live virus should end after 6-8 weeks, but since your girl still has symptoms of KC I would be careful about taking him out in public until she is well.

You might consider EC's hydrogen peroxide remedy for KC:

Good luck and thank you for sharing your story!

Hi--- re sneezing. See the video on EC about hydrogen peroxide inhalation method. I use it for myself, my cats and dogs too. You can try first a 1% solution and then use 3% if you feel it is ok.

No problem, cheap and it works on animals too.

Namaste, Om

Pharmaceutical companies are taking advantage of people, animals and children. These are billion dollar companies. I dont believe in doctors or vets when it comes to vaccines. I have refused to do this at the vet when they were telling me to vaccinate or dog can't be groomed. I ignored them and went to a groomer in town. Be careful with your pets and not just pets people and kids are being over vaccinated!! Please learn from this!!

We have a 10 week old male Labrador/Mastiff puppy. He started puppy class and we were told he had to have the Bordetella vaccine to continue. Our vet gave him the nasal spray vaccine. Within a few hours he was snippy and agressive - he had not previously been. As soon as we got home, he made a bee-line for our 5 year old son who was sitting on the floor and bit him. He ran a fever the rest of the day and through the night. We gave him some benedryl. He is eating and pooping fine today, and without fever. But he is still showing much more agression that he ever did before his shot. But there is still the agression. We are very sad indeed. This morning, he bit our 5 year old's pants and began to growl at him. He hasn't growled at any of us the whole week he has been home before yesterday's vaccine. I feel as if we have ruined our sweet puppy.

Just wanted to let people know Pfizer doesn't stand up and do the right thing when one of their vaccines cause adverse side effects. A multi-million dollar company can't reimburse a few hundered dollars in vet bills due to an adverse effect from thier Bordetella vaccine. They also only look into reactions if they get a substantial number - they don't review the data on a regular basis. I had a perfectly healthy dog prior to the vaccine but after he had a reaction which necessitated more vet visits. To this day, months later, he isn't the same dog.

My 11 year old Japanese Chin who was perfectly healthy just died suddenly five days after being administered the Bordetella shot orally at the kennel where she was staying while I was out of town. When I picked her up after 4 days of being there, she was lethargic and very thirsty--I thought she was tired from all the barking. She started throwing up and having diareha with fresh blood in it. She died a few hours later, before I could get her to a vet. I will never leave my babies at a kennel again or get shots!

Heidi, I am so sorry for your loss. Thank you for sharing so that others may benefit.

I'm so sorry for your loss!! I too have a Japanese Chin & just had her DHLPP & Bordatella done 4/12 & she's acting lethargic, not eating or drinking and walking like she has stiff joints. This started 3 days after her vaccine. She's 10 years old and I will never have her vaccinated unless its required by law.

Our 10 month old mutt had the vaccine nasal spray and he is wheezing and coughing and hacking.

Two days ago I had my 10 yr old Pomeranian vaccinated with the bordetella shot. By evening he had swollen up like a tick and had a hard time walking...barely even being able to pick up his head. He was also sore to the touch for when I pet him he shook from pain.

Luckily, I had metacam (an anti inflammatory) as well as Valium (for pain). I consulted the vet for proper dosages and by morning he was back to normal size. He's still taking both medications daily and I'm hoping the swelling will stay clear after the third day of meds.

This was the only shot administered that day which is why I am so certain it was the bordetella. However, my female Pom got the same shot the same day and had no side affects. It's a case by case aware and take immediate precautions.

Last wed my dog got her annual bordetella vaccine. Vet tried to do it orally up nose, but she refused most of it and then got really aggressive after showing teeth which we have never ever seen her do. He ended up doing it through shot. 2 days later she began coughing up phlem and 3 days later it turned into green stomach bile. and 4 days later she had 105.6 fever and we had to rush her to er vet. She had 3 visits of intravenous fluids to keep her from passing and we luckily switched up enough treats that were easy for her to eat despite the poor thing hacking to keep her food. After much medication and worry , a week later she is finally back to normal , but we are positive it was the bordetella that almost cost us to lose the love of our life!!

My 10 week old Wolf/husk high content hybrid has been severly congested (to the point of choking) since the eveing after his Bordatella vaccine 13 days ago. Steam and a towel with vapor rub on it just outside his crate at night helps but, I will NEVER give him that vaccine again and am hesitant to give him ANY vaccines in the future.

This is a deadly drug for any snubnose dog. Why must we give it to dogs at such a young age. They already have weak systems, this has cause upper respitatory infection everytime. Why not wait until they are older with a stronger immune system. Giving so many vaccines at one time is very unhealthy. If they want these dogs to get vaccinated then must the sale age greater.

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.

I will never give my handsome boy/ any pet a shot the rest of my life! My min pin got them today and he almost died. He is a healthy 5 year old! Thank goodness I have a dear friend that is the best vet in the world! She saved his life! This reaction took place 5 minutes after the shot! Never put that posion in your animals! Please take caution!

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.

I took my two chihuahua puppies in for their 16 week shots one month ago. All previous shots were well tolerated. I asked for the vet to give them a bordetella shot just in case I needed to board them when I go on vaation. Within minutes of administering the nasal vaccination, one of my puppies began snorting. I thought he was just trying to get the liquid out of his nose. It is now about a month later and he has developed a permanent cough. I am treating him with medication twice a day, but I don't know how long I will need to do this. The vet is now saying he has a collapsed trachea, but he never coughed before the bordetella. I think the vaccination did some permanent damage to him, or at the very least made a slight genetic issue much, much worse.

My little 3 lb chihuahua did the same thing. He now has a reverse sneeze that freeks most people out that he does daily. He had another reaction last week to his 3 year rabies shot which is the only one he still gets. His face was huge and he had hives and his fur was sticking out. Childrens benedryl and emergency vet were fabulous. No more shots for our dog... he'll get titers.

Bordatella allergic reaction:

Our one year old lab went in today for his routine vaccinations. A few hours later the vet called to say we forgot his Bordatella. Our lab received it (through the nose). About an hour later his eyes and mouth area were very swollen. The vet said to give him Benadryl. We also gave him a bag of ice to chew. This helped calm him and hydrated him at the same time.

My Boxer had her 16 weeks vaccine to help prevent the Bordatella virus.5 days after her nasal vaccine, she developed not just a little runny nose, but a full blown infection. Yellow mucus shooting out of her nose when she sneezed. Major pleghm and rolling cough from her throat. Presently taking Doxycycline with no improvement. Now going to Guelph University for further testing. It appears the vaccine did this to her. Now I find out most people do not recommend giving your boxer this vaccine. Boy is my dog sick right now. I hope she gets better soon.

Currently have a 17 week old Standard Poodle puppy going through the same thing, after all tests, and several antibiotics we are treating him for nasal mites. The vet doesn't think this is the problom but all symtoms cleared within 24 hours of giving Ivermectin.

I just took my 10 year old Chihuahua to the vet for a check-up last week. I was also talked into the Bordetella nasal spray vaccine. I specifically asked if there were any possible adverse side effects and was told there were not. Since then my dog has been sneezing, reverse sneezing and I think he had a seizure of some type on Saturday where his whole body stiffened up and he could stand on his own for about 5 minutes. He kept trying to get his paws up to his face. I am very angry that I was not told about possible side effects when I asked.

My dog received the intra-nasal vaccine for bordatella on Feb. 28, 2008 the next day she started to cough almost asmatic, a runny nose so full of mucous, constantly running also very tired out. She's only 3 yrs. old .Over the next few months she has been scoped, x-rayed, nebulized,and been on three different antibiotics,$1,000.00 later to no avail.The vet chalked it up to an allergy. At which I called Schering-plough the company which makes this vaccine. The vet there said to take her back and they would pay for a battery of tests to see if the Bordatella was responsible. Of course after waiting 3 weeks for results they said Bordatella didn't show up. My dog was a healthy energy filled dog until this. Now she's very lathargic and sleeps alot. I will not vaccinate my dog again I will go all natural. To see her so sick and uncomfortable and shortness of breath breaks my heart and angers me to know the vets continue to over vaccinate.

Both of my dogs - a female Shih Tzu and a male Pekingese - had the bordetella vaccines this past Monday. Within a couple of days, they were both extremely lethargic, and have been sort of "snorting" (I guess this is called "reverse sneezing"?). I took them back to the same vet on Saturday, and he did a blood test on the Peke, as he was the worst, and his white blood count was above normal, but everything else was normal. He said to give them both liquid Benedryl every 8 hours for 3 days, then once a day for the next 2 weeks. I haven't noticed any significant difference so far, but have only administered 3 times so far, so hope it helps soon.
