My pup is currently on Frontline Plus and my vet just gave me a free sample of Interceptor as the dewormer. I am new to all of this, so I have a couple of questions. What are you thoughts on the above products? Is there something else I should consider? Also I know there are places that you can get the products online and was thinking about purchasing online instead of the vet, but wanted to get thoughts on that as well. I have not even compared pricing yet, so if it is close or only a couple of bucks more, I will just get through vet.
