Great dewormer product definitely works

Ordered this last year I think it was & never got it. I ordered it again this year & got it. This dewormer works great & I love using it cause it gets the worms outta the adult dogs as well as the puppies

GREAT DEWORMER

I am a Frenchbull dog breeder and this is what I deworm my puppies with. Great product and saves a lot of money you would have spent at the vet. It’s safe and easy to use. Pups don’t really like the taste but that’s normal for most dewormers. It lasts a long time, I had a litter of 5 and dewormed them numerous times and still have plenty.

Great product for the price

As a cavalier, King Charles spaniel breeder I use this on my adult dogs as well as deworm for my puppies. I feel like it’s super cheap and they my dogs seem to like the taste of it. They don’t gag and my oldest dog is sick and he’s never had worms so that’s a plus.
