Is it normal for my dog to be acting weird a week after taking Trifexis?

About a week ago, I gave my dog Trifexis for his routine flea and heartworm prevention. Since then, I've noticed he's been acting a bit off - more lethargic and not as eager to play as he usually is. Is this something that can happen after taking Trifexis, or should I be concerned about these changes in his behavior?

Answer

It is possible for some dogs to experience lethargy after taking Trifexis, as every dog reacts differently to medications. It's important to monitor your dog's behavior and consult a vet if these changes continue.

  • Lethargy can occur as a side effect of Trifexis in some dogs.
  • Most side effects are mild and temporary, but it's important to monitor your pet.
  • Consult a vet if symptoms persist or worsen.

Trifexis is a widely-used medication for flea and heartworm prevention and is generally safe. However, some pets may experience side effects like lethargy or decreased appetite. These are usually mild and resolve on their own. If your dog’s symptoms persist or you notice any new symptoms like vomiting, diarrhea, or significant behavioral changes, it may be beneficial to consult a veterinarian for guidance.
