Best for

Owners who want a liquid they can measure to the dog's exact weight and stir into a meal instead of hiding a pill or breaking a tablet into pieces.

Skip if

You would rather use a single flavored chew with a fixed dose per weight range, since a liquid means measuring the dose yourself every time.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other dog food and health supplements we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.

Overview

This is a 10 percent fenbendazole suspension sold in a 100ml bottle with a 3ml dosing syringe, listed as a broad spectrum option for roundworm, hookworm, whipworm and tapeworm and marketed as easy to mix with food. The product weighs 4.6 ounces packaged and ships in a compact bottle.

At $37.98, it sits in the middle of the price range for liquid dewormers in this category. The listing is new, with a 3.9 star average from only 13 reviews, so the review history here is thin compared to established brands like Panacur.

Because it is liquid rather than a chewable tablet, dosing is based on measuring with the included syringe against your dog's weight, which some owners prefer for accuracy and others find less convenient than a pre-measured chew.

Pros

  • 10 percent fenbendazole liquid suspension covers roundworm, hookworm, whipworm and tapeworm
  • Includes a 3ml dosing syringe for measuring by weight
  • Mixes into food rather than requiring a swallowed pill
  • 100ml bottle offers multiple doses per purchase

Cons

  • Only 13 reviews and a 3.9 star average, a small and mixed sample to judge from
  • Liquid dosing requires more careful measuring than a fixed-dose chew
  • Newer listing with limited track record compared to established dewormer brands

Frequently asked questions

What worms does this liquid fenbendazole target?

The listing describes it as a broad spectrum dewormer for roundworm, hookworm, whipworm and tapeworm. This is not veterinary advice, so confirm with your vet which parasites your dog actually has before treating.

How is the dose measured?

It comes with a 3ml dosing syringe so you can draw up liquid and mix it into food based on your dog's weight. Follow the package directions and check with your vet if you are unsure of the right amount.

Is this a good choice if my dog will not take pills?

Yes, a liquid that stirs into food can be easier for dogs who spit out or refuse pills, though you will need to measure each dose yourself rather than relying on a fixed-size chew or tablet.
