Answer

It's understandable to be concerned when your dog appears lethargic and disinterested in food after taking a dewormer. While some mild side effects can occur, it's important to monitor your dog closely.

  • Monitor your dog's behavior over the next 24 to 48 hours.
  • Ensure your dog is drinking water and has opportunities to rest.
  • Contact a vet if symptoms persist or worsen.

Deworming medications can sometimes cause mild, temporary side effects, such as lethargy and a reduced appetite. This reaction usually passes within a couple of days. However, if your dog continues to show these symptoms or develops more serious ones, such as vomiting, diarrhea, or changes in behavior, it’s important to contact a veterinarian for further guidance.
