The timeframe for when you might see worms in the feces can vary depending on several factors, including the type of worms present, the specific deworming medication used, and the individual puppy's response to the treatment. Some puppies may pass dead or dying worms within a few hours or days after deworming, while others may not show any visible worms at all.
It's essential to follow the deworming schedule recommended by your veterinarian, even if you don't see worms in the feces. Regular deworming helps to prevent parasite infections and ensures the puppy's overall health and well-being. If you have any concerns about the effectiveness of the deworming treatment or if you notice any significant changes in your puppy's health or feces after deworming, it's always best to consult your veterinarian for further guidance.
