Easy order

Love the ease of ordering and that it's shipped to me. I love that I don't have to make a trip to the veterinarian office.

How the order was impossible to fill

They lost the prescriptions. We’re supposed to call the vet on the second one and didn’t. Totally impossible to get both filled
