I have ordering from Discount Pet Med for about the last three years. I have three dogs and when the vet recommended this product I bought it from the vet for twice as much money. It gets so expensive and my vet chooses not to give me a script so when I found it here for half the price and not vet appointment for the script it was a win!! Best price & I recieved in the 10 days. Will ALWAYS order from here & tell everyone to order from here.
