Sorry about your little doggie but don't worry the hair will grow back! I groom my little schnauzer and I have to be really careful not to the let the blades overheat. I spray a product called Kool lube to cool the clippers on occasion. The reason why I started to groom her myself is she got a nasty clipper burn on her ear one time while at the groomers. It started out small and gradually over a day grew into a nasty blister. Keep an eye on her boo boo and I think aloe vera is a great idea.
