It treats a wide variety of worms, including two types of tapeworms, roundworms, and hookworms, which covers most common intestinal parasites. The chewable tablet form is convenient and flavored, which may help if your dog is picky or resistant to pills.

After administering, watching your dog ensures they swallow the full dose.

This product is vet-quality and has strong user ratings, suggesting it’s generally safe and effective when used as directed. Like with any dewormer, it’s recommended to talk to your vet before and after treatment to confirm diagnosis and check if follow-up doses or tests are needed. Side effects are not detailed here, but vet consultation helps manage any risks, especially for sensitive dogs. The package contains six doses, which is helpful for multiple treatments.

If you have a smaller dog or a breed outside the specified weight range, you might need a different product. PetArmor 7 Way De-Wormer provides broad parasite protection in an easy-to-administer form, making it a reliable, vet-recommended option for medium to large dogs.

Elanco Drontal Broad Spectrum Dewormer offers a solid solution for pet owners dealing with common parasites like tapeworms, roundworms, and hookworms. This product is suitable for dogs and is particularly beneficial for those needing a dewormer that can cover a variety of worm types. It is designed for animals over 1 month old and weighing at least 1.5 pounds, making it safe for a wide range of dogs, including those of different breeds and sizes.

One of the key strengths of this dewormer is its broad-spectrum effectiveness. The flexibility in dosing, with one tablet required for every 4-8 lbs of body weight, makes it easy to use for dogs of various sizes. The option to administer the tablet directly or mix it with food is also a plus, as it can simplify the process for pets that may be reluctant to take medication.

There are a few drawbacks to consider. Side effects can occur, although they are generally mild, so it’s important for pet owners to monitor their dogs after treatment for any unusual reactions. Additionally, some pet owners may find the need for multiple doses depending on the severity of the infestation, which could be inconvenient. From a veterinary perspective, Elanco is a trusted brand, but it’s always advisable to consult your veterinarian before starting any deworming regimen.

PetArmor 7 Way Dewormer is designed for small dogs and puppies weighing between 6 and 25 pounds, making it a good choice if you have a little dog or young pup. It targets seven types of common worms including tapeworms, roundworms, and hookworms, which covers many of the common parasites your dog might face. The chewable tablet form is flavored, which tends to make it easier to give compared to pills or liquids. You only need to give the right number of tablets depending on your dog's weight, and it’s safe for puppies 12 weeks and older.

One important point is to watch your dog after giving the tablet to ensure they actually swallow the full dose. While this product is vet-quality and has strong customer reviews, it's a broad-spectrum option meant for general worm control. It’s recommended to check with your vet, especially if retreatment is needed or if you want to confirm which parasites are present through a fecal test. Deworming frequency can vary depending on factors like where you live and your dog's lifestyle.

This dewormer is a convenient, chewable option for small dogs and puppies to protect against multiple common worms, but it is important not to skip professional advice to ensure it’s the right choice for your pet’s health.
