Here's why:
* Deworming medication is designed to kill worms. The medication targets the worms and eliminates them from the dog's system.
* You may see worm fragments. Even after successful deworming, you may see some worm fragments in your dog's stool. This is because the medication doesn't always break down the worms completely. These fragments are usually much smaller and less noticeable than live worms.
* Worms can re-infect. If your dog is exposed to worms again after deworming, they can become re-infected. This is why it's important to continue deworming according to your veterinarian's recommendations.
If you see live worms in your dog's stool after deworming, it's crucial to contact your veterinarian immediately. They can help determine the reason for the persistent infection and recommend the appropriate course of action.
Remember, it's essential to follow your veterinarian's instructions for deworming, which will include the type of medication, dosage, and frequency. This helps ensure your dog receives the best possible treatment.
