Dog had a weird reaction after lepto vaccine, how worried should I be?

Earlier today, my dog received the leptospirosis vaccine and soon afterward seemed to have a strange reaction. He’s been a bit more lethargic than usual and didn’t seem interested in playing or eating dinner, which is unusual for him. Is this something that tends to happen after this vaccine, or is there a reason for concern?

Answer

It is not uncommon for dogs to feel a bit lethargic or lose appetite temporarily after receiving vaccines, including the leptospirosis vaccine. These mild symptoms are usually short-lived and not a cause for major concern.

  • Lethargy and reduced appetite are common mild vaccine reactions.
  • Symptoms typically resolve within a day or two.
  • Monitoring your dog during this time is important.

After vaccinations, some dogs might experience temporary lethargy and a decrease in appetite as their immune system responds to the vaccine. These reactions are usually mild and resolve within 24-48 hours. If your dog continues to show signs of discomfort, or if symptoms worsen, it's best to consult your veterinarian.
