My fiance has taken over his daughters dog care - but is having great difficulty in booking the dog in for grooming - the dog is very overgrown and has matted ears - I suggested that I clip the dog until an appointment is available - fiance said he'd be very cross with me if I did it - surely it's in the dogs best interest to be able to see where it's going and to get rid of the mats on his ears which the dog rubs at?
