Answer

It is not uncommon for dogs to experience increased tiredness after receiving the leptospirosis vaccine. This reaction is typically mild and short-lived.

  • Post-vaccine lethargy is common and usually resolves within a day or two.
  • Monitor your dog for any additional symptoms.
  • Consult a vet if the lethargy persists beyond normal recovery time.

The leptospirosis vaccine, like any vaccine, can cause temporary side effects such as tiredness, mild fever, or soreness in your dog. These symptoms are generally mild and should pass within a couple of days as your dog's immune system adjusts. If you notice any alarming symptoms like vomiting, swelling, or difficulty breathing, please contact your vet immediately.
