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 Elanco Drontal Broad Spectrum Dewormer is designed to treat a variety of worms including tapeworms, roundworms, and hookworms. One of the key strengths of this product is its broad-spectrum effectiveness, making it a versatile option for dog owners dealing with multiple types of parasites. Additionally, the medication comes in the form of tablets, which can be administered directly or mixed with food, providing flexibility in how it is given to your pets.

Each tablet is intended for cats and kittens over one month old and weighing more than 1.5 pounds, with a dosage of one tablet per 4-8 lbs of body weight. This allows for precise dosing based on the animal's weight, which is crucial for effectiveness and safety. However, it is important to note that this product is specifically labeled for cats, even though it could potentially be used for small dogs, careful consideration and possibly veterinary guidance would be necessary.

The product comes in a bottle of 50 tablets, making it a cost-effective option for multi-pet households or long-term use. The Elanco Drontal Broad Spectrum Dewormer is a reliable and flexible option for treating a range of worms in cats and kittens but may require additional attention if considering for small dogs.
