I have given Copper Frontline for fleas ever since we got him (12/05). Each and every month we go through the same situation. I put it on him, and for the next 1/2 hr to 1 hr he paces the apartment. He'll sit/lay for a few seconds and then get up and try and find a new place to lay. I think the smell bothers him and he is trying to get away from the smell. The past 3 or so months I will put it on and then give him a raw bone to chew on, but last month that couldn't even distract him. I got Advantage this month to try. I was wondering if anyone else had this problem and if so, what have you done to help fix the situation.
