I had my dog vaccinated a couple of hours ago, and now he's acting really sluggish. Should I be concerned, Dial a Vet?

I took my dog to get his vaccinations earlier today, and ever since we got back home, he's been acting unusually sluggish and not his usual energetic self. He’s just lying around and seems a bit out of sorts. Is this a normal reaction to vaccines, or should I be concerned and take further action?

Answer

It's common for dogs to feel a bit under the weather after vaccinations. Slight lethargy and mild changes in behavior are typical post-vaccine responses.

  • Vaccination reactions can include tiredness and slight discomfort.
  • Monitor your dog for improvement within 24–48 hours.
  • Contact a vet if symptoms persist or worsen.

After vaccinations, some dogs might experience mild side effects such as fatigue or slight discomfort. These symptoms are usually temporary and result from your dog's immune system responding to the vaccine. Typically, these signs resolve within a day or two. It's important to allow your dog to rest while keeping a close eye on their behavior during this time.

Book a consultation with a licensed vet at Dial A Vet for just $49 AUD if you're unsure or symptoms are getting worse.
