Brushing your dog ventilates their coat, helping it grow healthy and strong and takes away old and damaged hair. Grooming also ensures that your dog’s skin can breathe and keeps down the level of grease in their coat. Too much grease can block pores and cause irritation and all sorts of skin problems. When your dog gets groomed less often they tend to be more anxious, however with consistent grooming every 6 weeks it feels more like a relaxing spa treatment..
