10 Best Dog Wormers 2025 in the United States

The PetArmor 7 Way De-Wormer for Dogs is a versatile and convenient oral treatment for large dogs and puppies over 25 lbs. It effectively treats and controls seven species of worms, including tapeworms, roundworms, and hookworms. The medication comes in chewable tablets, making it easier to administer compared to non-chewable forms. The flavored tablets enhance palatability, which can help ensure your dog takes the full dose without rejection.

Suitable for puppies as young as 12 weeks, this product covers a wide age range and is safe for dogs weighing between 25.1 and 200 lbs, making it ideal for medium to large breeds. Users should monitor their dogs after administration to ensure they consume the full dose and follow label instructions for the best results. It's also recommended to consult a veterinarian for re-treatment or if your dog shows persistent symptoms to rule out other issues or parasites.

Some drawbacks include the limitation to larger dogs and the necessity of multiple tablets for heavier dogs, which could be less convenient. Additionally, while it covers a broad spectrum of worms, it doesn't address all possible internal parasites, so consulting a vet for comprehensive treatment is advisable.

The PETARMOR Sure Shot 2X is a liquid de-wormer designed to treat common roundworms and hookworms in dogs, effectively addressing these common parasites. It works on 4 types of worms and helps prevent the return of large roundworms in adult dogs. Because it comes in liquid form, dosing is straightforward: you give 1 teaspoon (5 mL) for every 10 pounds of your dog’s weight, making it easy to get the right amount, especially for dogs of different sizes.

It's safe to use on puppies as young as 2 weeks old and can be given to dogs of all breeds and sizes under 120 pounds. For puppies, multiple doses are recommended at specific weeks for thorough protection, and adult dogs in risky environments should be treated monthly. One advantage is its vet-quality assurance and strong customer ratings, suggesting reliability. However, the bottle is only 2 ounces, so larger dogs or multiple dogs might require multiple purchases.

Additionally, it primarily targets roundworms and hookworms, so if your dog has other types of worms, this product may not cover those. PETARMOR Sure Shot 2X offers a convenient and trusted option for routine worm control, especially suited for households with puppies or dogs prone to roundworm and hookworm infections.

The SENTRY HC WORM X PLUS 7 Way De-Wormer is a broad-spectrum dewormer designed for medium and large dogs weighing over 25 lbs. It effectively treats and controls two types of tapeworms, two types of roundworms, and three types of hookworms using the active ingredients pyrantel pamoate and praziquantel, which are commonly found in veterinary brands. One of its significant strengths is that it is available over the counter, eliminating the need for a prescription, making it accessible for pet owners.

The medication comes in the form of tasty chewable tablets that are easy to administer with or without food, enhancing convenience for dog owners. The product is suitable for dogs aged 12 weeks and older, ensuring it can be used for both adult dogs and older puppies. Dosage instructions are clearly outlined based on the dog's weight, simplifying the treatment process. Regular treatment is recommended to keep your pet free from worms.

However, one drawback is that this product is not suitable for small dogs or puppies weighing less than 25 lbs, so a different product would be needed for smaller pets. Additionally, the package includes only two tablets, which may not be sufficient for multiple treatments depending on your dog's size. Despite these minor limitations, SENTRY HC WORM X PLUS offers an effective and convenient solution for deworming medium to large dogs.
