My 12-week-old puppy just got its second round of shots and now seems really tired. Is this normal?

Yesterday, my 12-week-old puppy received his second round of vaccinations, and ever since we've been home, he seems unusually tired, napping much more than usual. I wonder if this is a typical reaction to the vaccines or if I should be concerned about this lethargy. Is this something I need to address, or will he perk up soon on his own?

Answer

It is not uncommon for puppies to feel a little tired and lethargic after receiving vaccinations, as their bodies are working hard to build immunity. Monitoring your puppy is important, and if symptoms persist, contacting a vet can provide peace of mind.

  • Fatigue is a normal response to vaccination.
  • Keep an eye on other symptoms.
  • Contact a vet if lethargy continues beyond a day or worsens.

Vaccinations are an essential part of keeping your puppy healthy, but they can sometimes cause side effects such as tiredness or discomfort. This should typically resolve within 24 to 48 hours. Rest is the best medicine, but ensure your puppy is still drinking water and able to move around without difficulty. If your puppy's energy doesn't return or they develop new symptoms such as swelling or persistent crying, it's best to consult a veterinarian.
