Is it normal that my week-old puppy got dewormer at the vet today and now seems really sleepy?

This afternoon, I took my week-old puppy to the vet for her first deworming treatment. Ever since we've been home, she seems unusually sleepy and is napping a lot more than usual. Is this a common reaction to the dewormer, or should I be concerned about her being so drowsy?

Answer

Your puppy's increased sleepiness after the deworming treatment is likely a normal reaction. Puppies can sometimes feel a little tired or drowsy following such treatments.

  • Increased sleepiness can be a common reaction to deworming.
  • This symptom typically resolves on its own.
  • Monitor your puppy's condition over the next 24 hours.

Puppies, especially at a young age, can have varying reactions to veterinary treatments. Dewormers work by tackling internal parasites, and in doing so, they can sometimes make the puppy feel a bit off. This drowsiness is typically mild and temporary. Ensure she stays hydrated and continue to watch for any other concerning symptoms like vomiting or extreme lethargy.
