Lifesaver!!! Very effective!

Our poor puppy has gotten Giardia repeatedly and we’ve spent hundreds on vet visits treating it. We’ve seen two different vets and he has taken several antibiotics. Our latest vet prescribed two 4g boxes for our 70 pounds golden retriever. We were relieved to see we could buy it online for half the price! It’s great for other dog owners who have puppies who are prone to getting parasites. Highly recommend, especially for the price and convenience!

Need enough for three days

Vet recommended, did the math for all the dogs. Nowhere did it say that each dog needed full dose for three days. Only one is wormed now.

A lifesaver!

The fact that this can be purchased without a script makes life so much easier. My 3 dogs kept giving it to each other and one was having real problems with diarrhea. I was able to order this so all the dogs could be treated at once and we could be done with giardia. Saved our lives! Thank you Chewy!

Helps with diarrhea and parasites

Eliminates the upset stomach, but my dog did not like the taste and texture in his food. I just added some wet dog food to encourage my dog to eat with this medicine.

Great product, pricey

Great product, the price has taken a hike from $5-$6 up to $20. This is the only reason Chewy will not have me as a repeat customer. I’ve been watching the price of this particular dewormer rise exponentially over the past couple of years. Absolutely not affordable when you have 2 pits weighing in at 118lbs and 75lbs. Sorry chewy, but you need to have the average Joe in mind. You’re catering to people where money is not an issue apparently.
