My puppy is 14 weeks and just got his second vaccine dose, is it normal for him to be so sleepy and not wanting to play?

This afternoon, after my puppy received his second vaccine dose, I've noticed he's unusually sleepy and isn't as interested in playing as he usually is. While I know vaccines can sometimes cause mild reactions, I'm worried because he seems more lethargic than I expected. Is this normal, or should I be concerned about his lack of energy?

Answer

It's normal for your puppy to feel a bit more tired than usual after receiving a vaccination. However, it's important to monitor his condition to ensure he doesn't show any severe symptoms.

  • A slight lethargy can be a common reaction post-vaccination.
  • If symptoms don't improve, contact a veterinarian.
  • Always watch out for more serious signs like vomiting or difficulty breathing.

Vaccinations can sometimes cause mild side effects in puppies, including lethargy or a decrease in appetite. These reactions are usually short-lived and should resolve within 24-48 hours. Ensure your puppy remains hydrated and comfortable during this time. If there's no improvement or if you notice any worsening symptoms, please consult a veterinarian to rule out any adverse reactions.
