Dog seems really tired and not eating much after getting shots yesterday. Is this normal or should I be worried?

Yesterday, my dog got his vaccinations, and today he seems unusually tired and isn't eating much at all. He’s usually so energetic and has a good appetite, so seeing him like this has me concerned. Is this normal after getting shots, or should I take him back to the vet?

Answer

It’s normal for some dogs to feel a bit tired and lose their appetite after vaccinations. This is usually a temporary response to the vaccine.

  • Temporary fatigue and reduced appetite are common side effects.
  • Monitor your dog's condition for any changes or worsening symptoms.
  • Most side effects are mild and resolve within a day or two.

Vaccinations help protect your dog from various diseases by stimulating the immune system. It’s not uncommon for this to lead to mild side effects like tiredness or a slight decrease in appetite. These symptoms usually resolve on their own in a short period. However, it’s always good to keep an eye on your pet, and if you notice any severe reactions such as vomiting, breathing difficulties, or swelling, contact a veterinarian promptly.
