Product is short dated and though I ordered a six month supply, it was only good for two months. Spoke to customer service, they reshipped with the EXACT same expiry date. Texted with a pharmacist who asked me to mail back the product and told me he sent a prepaid label and I boxed it up (it's still on my counter) and never received the label. At this point, I give up. Chewy is normally so, so good about fixing issues, but this has been absolutely unacceptable.

I jus received this item recently. I will use it next month for the first time....as Chewy was out of stock on my regular item. My vet suggested this item as a substitution. I am hoping it will work just as well....also it is about half the price of my previous item...so it is possible that I might be switching!

I purchas this for my dog because it's a lot more expensive at her vet. For 1 it's $25 but for 3 it's $83! Math wasn't my best subject in school but I graduated from high school and college and I know that should be $75. I don't have the ability to get there once a month. So when I found out I can get it from you cheaper and delivered, it was a great solution!

Stopped!

I personally stopped using this product after a couple of years trying to figure out why my Dude scratched soooo much and Thought he had all year round allergies as the vet said and I paid for Allergy shots that didn’t work! So I STOPPED using this product and he stopped scratching! ( just my Dogs reaction ) Product DID keep him flea & tick free.
