10 Best Worm Treatment For Dogs 2026 in the United States

NexGard Plus is a monthly chewable tablet designed for dogs weighing between 33 to 66 pounds, offering a convenient way to protect your dog from multiple parasites. It effectively treats roundworms and hookworms, which are common intestinal worms in dogs, while also preventing heartworm disease. The beef-flavored chew is easy to give, making it a good choice if your dog is picky about medication.

This product also kills fleas and several types of ticks, which adds extra protection beyond just worms. The treatment is taken once a month, providing year-round coverage when used regularly, which helps reduce the hassle of frequent dosing. It’s important to follow your veterinarian’s guidance to ensure safety and proper use, especially since the dose is specific to your dog’s weight. Customer reviews indicate good satisfaction, suggesting it is generally well-tolerated with few side effects.

If your dog is smaller than 33 pounds or larger than 66 pounds, a different dosage or product will be needed. While NexGard Plus protects against several common worms, it may not cover all types, so discussing your dog’s specific risk factors with your vet is recommended. This product is a reliable, easy-to-administer choice for medium-sized dogs needing broad parasite protection, combining worm treatment with flea and tick prevention in one chew.

The Elanco Drontal Broad Spectrum Dewormer is designed to treat a variety of worms including tapeworms, roundworms, and hookworms. It’s suitable for cats and kittens over one month old and weighing more than 1.5 pounds. One of the major strengths of this dewormer is its broad-spectrum effectiveness, making it a versatile choice if your pet is affected by different types of worms.

The medication can be administered directly by mouth or mixed with food, which offers flexibility in ensuring your pet takes it. Each bottle contains 50 tablets, which is convenient for long-term use or multi-pet households.

It is worth noting that this product is specifically formulated for cats and not dogs. If you have a dog, you would need to look for a product specifically designed for canine use. Additionally, always consult with your vet to confirm the safety and proper dosage for your pet's specific needs. While Elanco is a reputable brand, it’s crucial to make sure any medication is appropriate for the particular age, weight, and health condition of your pet.

Advantage Multi Topical Solution is designed for dogs weighing between 55 and 88 pounds, offering protection against a range of parasites including heartworms, fleas, roundworms, hookworms, whipworms, and sarcoptic mange. Its main strength lies in its 6-in-1 formula, which covers several common worms and pests in a single monthly topical treatment, making it convenient and effective for ongoing parasite control. The medication works through contact, so fleas don't need to bite your dog to be killed, which helps in quickly reducing infestations.

The topical form is easy to apply directly to the skin along the back, avoiding the need for pills or chewing tablets, which many dogs resist. This product is veterinarian-trusted and specifically formulated for adult dogs within the 55 to 88-pound weight range, so it’s not suitable for smaller or larger dogs without consulting a vet. Like any medication, proper application is important to avoid licking or ingestion immediately after use. Some dog owners may want to check with their veterinarian about potential side effects or compatibility with other treatments.

It is a strong option for pet owners seeking a comprehensive, once-a-month worm and parasite treatment that covers multiple threats in one easy dose.
