This happened to my dog Thumper. It took months for his hair to grow back. I thought it wasn't healing right and kept going to the vet because I never dealt with it before. Not you can't even tell he had a hot spot. The funny thing is the hair that came back has a tint of brown where he is mostly silver and grey.
