Deworming Puppies: What to Expect and How to Protect Your Pet
Learn everything you need to know about deworming puppies, from schedules to symptoms and prevention tips.

Why Deworming Puppies Is Essential
Deworming is a critical part of puppy care. Intestinal parasites like roundworms and hookworms are extremely common in puppies and can cause serious health problems if left untreated. These parasites can be passed from the mother to her puppies before birth or through her milk after birth. Even puppies with negative fecal exam results may still be infected, as immature worms may not yet be producing eggs that show up in stool samples.
Puppy Deworming Schedule
The recommended deworming schedule for puppies is designed to target parasites at different stages of their life cycle. According to the Centers for Disease Control and Prevention (CDC) and the American Association of Veterinary Parasitologists, puppies should begin deworming at 2 weeks of age and continue every 2 weeks until they are 2 months old. After that, monthly deworming is advised until the puppy is 6 months old.
- Start deworming at 2 weeks of age
- Repeat every 2 weeks until 2 months old
- Continue monthly until 6 months old
- Switch to an adult deworming schedule after 6 months
Common Deworming Medications
There are several types of deworming medications available for puppies. Most are broad-spectrum, meaning they are effective against a wide range of parasites. These medications can be administered as oral tablets, liquids, pastes, or even as topical treatments.
- Oral medications: Tablets, chewable treats, liquids, and pastes
- Topical treatments: Spot-on solutions like Revolution
- Injectable shots: Administered by a licensed veterinarian
How to Administer Deworming Medication
Administering deworming medication to a puppy can be straightforward, but it’s important to follow the instructions carefully. Here are some tips:
- Read the label for dosage instructions based on your puppy’s weight
- Use a syringe for liquid medications, placing it between the puppy’s jaws
- Hide tablets in treats if your puppy is reluctant to take them
- Follow up with a second round of medication 2–3 weeks after the first dose
