Your dog probably does not care if he has a grubby, messy face, but you do. Because the facial area can be delicate, pulling hair around the mouth, eyes, and ears will cause your dog discomfort, so brushing these areas will have to be done gently and carefully, to avoid discomfort for your dog. Holding your dog's face securely and supporting hair by holding it between your grooming tool and the skin will help reduce friction, making face brushing much more pleasant for your dog. Be sure to stop and take a break if face brushing gets to be too much for your pup. Give it a rest and come back later to finish the job.
