My dog got his second round of vaccines today and now he's really lethargic and not eating, is this a normal side effect or should I call the vet?

Earlier today, my dog had his second round of vaccines, and ever since we've returned home, he's seemed unusually lethargic and hasn't shown any interest in his food, which is quite unlike him. I expected a bit of tiredness, but this seems a bit more than that. Is this a normal reaction to the vaccines, or should I reach out to our vet for advice?

Answer

It is not uncommon for dogs to feel a little under the weather after receiving vaccinations, but significant lethargy and a complete lack of interest in food are more concerning symptoms.

  • Monitor your dog's behavior closely.
  • Consult your vet if there's no improvement within 24 hours.
  • Prompt action is necessary if new symptoms arise, or if these symptoms worsen.

Vaccines are crucial for your dog's health, but occasionally, they can cause mild adverse reactions. A bit of tiredness or tenderness at the injection site is normal. However, if your dog appears significantly more lethargic than expected or refuses to eat, it's a good idea to reach out to your veterinarian for further guidance. These signs might indicate a stronger reaction to the vaccine, and your vet can offer specific advice or treatments to help your pet feel better quickly.
