My pup got a vaccine yesterday and now he's all lethargic and not eating, should I be super worried or is this kinda normal post-vaccine behavior?

Yesterday, my pup received his vaccine, and today he seems really lethargic and isn't interested in eating at all. This change in his behavior has me a bit worried. Is it typical for dogs to react this way after vaccinations, or should I be more concerned about his condition?

Answer

It is common for dogs to experience mild side effects after receiving vaccinations. Some canines may become lethargic or show a decreased appetite temporarily as their bodies adjust.

  • Slight lethargy post-vaccine can be normal.
  • Temporary changes in appetite may occur.
  • Monitor your pup's symptoms closely.

Vaccinations are designed to help protect against diseases, and mild reactions like tiredness or a temporary loss of appetite are not uncommon. These should resolve within a day or two. However, if your pup's condition worsens or you notice other concerning symptoms, it’s a good idea to consult a veterinarian.
