Just wondering if any of you use advantage flea preventative, and if so, does your dog not like it. It is a oily substance that you put on their back once a month to prevent fleas, mosquitos, and ticks. Anyway, every month when i put it on Murphy, he hides in his kennel for the rest of the day like he is so upset. It is not suppose to be painful, so i don't know why it makes him so upset. i think it must itch b/c when he does finally go outside he rolls around and goes crazy. i know that they have sensitive skin, so maybe it burns. just wondering if anyone else has the same problem.
