Questions & Answers

5 Customer Questions

Can this be used monthly as a preventative treatment?
Answer by ChewyMay 12, 2021
This De-Wormer is not formulated as a preventative treatment. It is intended to be used as an active treatment for your dog.

Where is this product made? I notice the package says distributed by Sergeant’s from Omaha - but not where it was actually made.
Answer by ChewyJan 11, 2021
This product is made in the USA.

Do you only administer this de-wormer one time to get rid of tapeworms in a dog, or should it be repeated after a few days?
Answer by ChewyNov 29, 2020
One dose is the recommended monthly treatment. If you need to retreat your dog, we recommend consulting with your veterinarian and have them perform a fecal test to rule out any other issues or parasites.

25 lbs -200 lbs is a huge range. My dog is 40 lbs. I don't want him taking as much as for a 200 lb dog. Do they cut in half or have half dosing?
Answer by ChewyNov 07, 2021
This broad spectrum dewormer is formulated to be safe for medium and large breed dogs between 25.1 and 200 pounds. Feeding instructions are specified for dogs within this range. Pups weighing 40 pounds should only have 1 tablet. For a complete list of feeding recommendations, click the “Instructions” tab, next to the “Ingredients” tab, just under the product photos.

A Fantastic product.

This is a really great purchase because it's affordable and does the job perfectly. I was pleasantly surprised by how effective and easy to use the PetArmor 7 Way Dewormer for Roundworms for Large Breed Dogs is. It's hard to find a product that works well and doesn't break the bank, but this one definitely checks both boxes. I tried other options before, but they were either too expensive or didn't work as expected.

100% satisfaction

I tried 2 other dewormer medications before coming across this one and I must say this one took care of the issue completely. Also it only took 1 recommended dose to do so. I would recommend this dewormer to friends and family especially if you have large breeds.
