Parasiticides for Dogs

Reviewed by Dr. Angela Beal, DVM

Dog parasiticides help protect dogs from a range of internal and external parasites that can affect their health throughout the year. Fleas, ticks, heartworms, intestinal worms, mites, and other parasites are common concerns, and the right preventive medication can help reduce the risk of parasite-related illness. Because dogs have different lifestyles and levels of exposure, parasiticides for dogs are available in a variety of formulations that target specific parasites or provide broad-spectrum protection against multiple parasites with a single product.

At Chewy, you'll find a wide selection of veterinarian-approved dog parasiticides for puppies and adult dogs. The assortment includes flavored chewables, oral tablets, topical treatments, and other convenient options that may help protect against fleas, ticks, heartworms, intestinal worms, mites, or combinations of these parasites. Your veterinarian can recommend the most appropriate product based on your dog's age, weight, lifestyle, geographic location, and individual risk factors. Keep in mind the following considerations:

• Parasite coverage: Products may help protect against fleas, ticks, heartworms, intestinal worms, mites, or multiple parasites with a single product
• Treatment format: Choose from flavored chewables, oral tablets, topical treatments, and other veterinarian-approved options
• Broad-spectrum protection: Some parasiticides are formulated to help protect against several internal and external parasites at the same time
• Dog-specific needs: Your veterinarian can recommend a product based on your dog's age, weight, lifestyle, health status, and parasite exposure risk
• Consistent prevention: Following your dog's recommended parasite prevention schedule helps provide year-round protection

Keeping your dog on a consistent parasite prevention plan is one of the best ways to support their long-term health. At Chewy, you'll find veterinarian-approved dog parasiticides from trusted manufacturers, along with convenient home delivery.
