Vaccine reactions in dogs
Ask The Vet Home > Dogs > Dog Care > Vaccinations
Vaccinations work by stimulating the immune system in your dog by mimicking a 'real' virus or bacteria attack. Your dog's immune system then generates antibodies which act to protect him from catching it in the future. Whilst most vaccinations are carried out without event with only minor discomfort, some dogs can react violently to vaccinations and until it happens, you can't pick which dog will react and which won't.
Vaccination reactions range from mild reactions which typically result in a sleepier dog, sometimes with local redness or swelling at the vaccination point. These usually resolve after 24-48 hours and you don't need to do too much except to make sure your dog is comfortable and warm.
More serious reactions result in wheals forming in the skin of the dog. This usually occurs within the first hour or so after the vaccination and typically you'll notice swelling around the face and lips - for some it's so bad they can't even open their eyes. It is also usually extremely itchy for your dog. This can proceed to the more serious anaphylactic reaction where the dog experiences breathing difficulties, seizures, vomiting and/or collapses. Anaphylaxis is potentially fatal and needs to be looked at immediately. Most dogs who do have anaphylactic reactions to vaccinations do so within the first hour of exposure so thankfully, these when they do occur do tend to happen at the clinic where the vaccinations are taking place and therefore can be attended to quickly by the veterinarian.
Both anaphylaxis and urticaria are reactions that are triggered by antibodies that the immune system has made to some portion of the vaccine and usually requires at least one previous exposure to the vaccine. The antibodies cause inflammatory cells like basophils and mast cells to release substances that cause the allergic reaction. The impact on the dog may be life threatening but if treated successfully the prognosis for long-term health is good. Mild reactions usually resolve without treatment.
Having said that, the risks of a dog having adverse reactions to vaccinations aren't very common and the benefits of having a vaccinated pet protected from potentially fatal diseases far outweighs the risk which is why most veterinarians will advise the vaccinations of all dogs.
I would suggest however that you schedule your veterinary visit so that you can monitor your dog after the vaccination to ensure that you will pick up on any untoward effects of the vaccination.
There have been some reports of some dogs who have local reactions to vaccines which result in a lump in the area - seems to happen more often with the rabies vaccine. These lumps can take up to 2 months to resolve and most times don't cause the animal any pain or discomfort. For some dogs these lumps don't seem to resolve and can last for longer than that - if that is the case, visit your veterinarian to discuss your options which may involve surgical removal of the lump.
If your dog has a history of reactions to vaccines, let your veterinarian know so that he/she knows not to administer them again the next time.

Vet question of the day
Sudden death in dog
Let me explain my scenario: I am 19 years old and came home from work today to find my beagle (8yo female neutered), Kaylee, lying on my back porch, dead, with a very swollen stomach and a lot of blood that had come out of her nose and mouth. I am having a very hard time dealing with the loss as I loved her very much and she was much more than just a dog to me. She had no health problems except she was a little overweight because, well, she loved food. Now, I never allowed Kaylee to go out in the front yard because it wasn't fenced in. I took her on walks instead. The back yard however is fenced in with no plants except for grass in it. Kaylee and my other dog, Duke, have gone in the back yard since they've been living at my house and have never come back with any illnesses, let alone dying. My dad does give the dogs bones once in a while but they are never sharp chicken-type bones, just round and dull for them to chew on. I am deeply saddened by the loss and I just have to know what exactly killed my beloved dog. She meant too much to me to just allow her death to go without knowing what killed her. Please help, I don't have the money to ask my vet for an autopsy. I just want to know what the possible situations are that killed her. The night before she died (last night) I saw her around 1am before going to bed and she was completely fine and happy. Please help..like I said, she meant way too much to me to just allow her to go without knowing how she went. How could she have died..and..was she in pain? Thank you very much for reading..I look forward to your response. - Click here to read the answer
