Buying Guide

Know the parasite type

Choose a product that targets the parasites you need treated, such as roundworms, tapeworms, or Giardia, since ingredients vary by target

Check active ingredients

Look for proven actives like praziquantel, pyrantel pamoate, fenbendazole (Panacur), or mebendazole and match them to the parasite profile

Match formulation to your dog

Select chewables, liquid suspensions, or granules based on your dog's size, age, and ease of administration for accurate dosing

Confirm age and weight dosing

Verify the product is labeled safe for puppies or small dogs and that dosing increments align with your dog's weight to avoid under- or overdosing

Consider broad-spectrum options

Broad-spectrum dewormers cover multiple parasite types and can simplify treatment when mixed infections are likely
