Thank you everyone for the information. I will try to find the best product for my situation. We have found a few fleas on Riley. They are definitely in our yard, so i am going to treat the yard as well. I just want to make him more comfortable, i'm sure he doesn't like the itching these little nasties cause. Why do fleas even have to exist in the world?? Wouldn't it be so much nicer if they just didn't?
