I live in a small town and our vets don't carry this product. They solely believe in Frontline for flea and tick protection and heartguard for worms. I was wanting your take on the product. How safe is it? Does it have many side affects or why would my vet not like it. I asked him several times and he just claims the ones he carries is better.
Basicly it becomes too expensive to carry every product available for heartworm and fleas etc.. Sentinal is excellent with close to no side effects. vetcare
