I'll try and post some pics of Nikki if I can get him to sit still long enough

As of right now, he is taking topical frontline plus and the heartworm pill I am almost certain is tablet form once a month. I noticed this morning that he always seems to bite just above his tail on his back and on his front paws. There always seem to be little scabs above his tail. I don't know that it's food allergies, we have been very careful to make sure he only has his own dog food. It's moist hill's k/d diet, at night he seems to prefer the dry dog kibble. Also when he's sleeping in bed with my dad, he will wake up in the middle of the night and scratch and bite himself moreso then than in the daytime. When my mom takes him to the vet this friday, we'll see if we can get something figured out. She already plans on asking about it. Thanks guys!
