Vaccination for dogs should only be performed if the dog is healthy. Vaccines can fail or cause dangerous reactions if administered to an unhealthy pet. Here's what you need to know about vaccinating sick dogs.
Dogs Who Should Not Be Vaccinated
Vets agree that dogs suffering from any of the following illnesses should never be vaccinated:
Autoimmune disease
- Dogs undergoing chemo or radiation therapy, or who have cancer
- Pets who are recovering from surgery
- Pets infected with parasites
- Pets who are under chronic stress
- Malnourished pets
- Dying pets
Why Sick Dogs Shouldn't Be Vaccinated
Vaccines are intended for use in healthy animals only. Sick dogs are at increased risk of drug reaction, including anaphylactic shock and death. At best, your dog may not receive the full protection intended if he receives the vaccination while ill. This may leave your dog vulnerable to diseases such as rabies and canine distemper, without you even knowing it.
Successful Vaccination When Your Dog Is Ill
If possible, allow your dog adequate recovery time before administering vaccinations. It's better to let your dog's vaccinations lapse for a week or two than to put him at risk of dangerous drug reactions, or to allow him to continue being vulnerable to disease.
If your dog is suffering from a serious illness, you should consider refraining from vaccinations not required by law.
