Luna has been itching a little too much for my liking for about a month now. I haven't seen one bug on her. She has very fine short puppy hair so I would be able to tell (I think). And I have given her flea treatment every month.. the liquid one that goes down her back. Then, I noticed her flapping her ears back and forth like 5-6x a day for the past week now. So today I gave her Excel medicate ear remedy and I *think* it has helped. I also examined her ears.. no sign of hair falling out, ear mites, or wax build up. Then today, I noticed her knawing at her tail. At one point it looked like a whitish scab with pus. The hair is still covering it up but I'm pretty sure there's a scab underneath. I also gave her a bath today... any advice??
