Stopped my dogs from having anymore worms within 48hours. I will buy this 10X over any other brand.

Puppies do NOT like this. Neither do the parents. I do not reccomend.

I have used Happy Jack dewormer in the past and thought it was a decent product but with a recent litter of Golden Retriever puppies, our experience could not have been worse. We dewormed all 10 puppies according to the Happy Jack label and, for the 1st 6 weeks, he had no issues. All 10 puppies grew and seemed to be in great health. At 6 weeks, we went to have a wellness check and they all checked out and had clean bills of health. At 6 weeks old, we had to start a new bottle of happy Jack dewormer. They got that bottle at 6 and 8 weeks and I think it was defective because several families reported having to rush their pup to the vet to be treated for severe anemia and hookworms. To be fair, 2 of the families did pick up their pup at 7 weeks and did not deworm at 8 weeks as recommended. 5 of the pups had been dewormed at 8 weeks and still tested positive for hookworms. The other 3 families did not report any health issues at all. Their pups were playful and healthy. For a little more info, we started weening at 3 weeks, by 6 weeks they were totally done with Mom. They seemed to absolutely hate the taste of the medicine. Often squirming and shaking their heads after drinking. Never any vomiting though. This was a very sad ordeal costing several families thousands of dollars for emergency vet care. I'm hoping this review will help others make informed decisions when purchasing dewormer.

Product made all of my puppies begin trying to induce vomiting. They all gagged for a significant amount of time after administering not palatable at all
