My boyfriend's Australian Cattle Dog is leaving the most hair in the house - he could seriously need his coat brushed on a regular basis,but we need to get rid of the current overload of dead fur. Having only owned shorthaired dogs, do any of you groomers have suggestions for a coat-appropriate brush? (I'm hoping to get his coat brushed twice a week and see if that culls out enough dead hair that we can back it down for just maintenance.) Thanks for the suggestions!!! He hates being brushed, according to BF, so the more enjoyable for him, the better (treats, etc)
