Hi Ive been homecooking for my two boxers zoe(2) and zack 10 weeks.They seem to be doing really good except I've noticed they have been growing some excess hair in their ears(they are starting to look like my dad ) and around their behinds!! It's really weird.First I thought it was because zoe was coming out of heat.But then the puppy started to have it too!!I have been giving them brewer's yeast with their food.Could that be it??Help before i have to get a ear hair trimmer and I dont know what for their butts!!
