If your dog seems to be blowing unusual amounts of coat, consult your veterinarian. After you have thoroughly brushed your dog you will be ready to bathe it. Common sense should be your guide. If your dog is smelly, itchy or shedding profusely, reach for the shampoo. Some dogs require baths every week, while others can go months without need of soap and water.
Some breeds are rough and tumble, others are more fastidious.
You must tailor your grooming accordingly. Choosing grooming products is important. And don't even consider using shampoos made for people on your pets. Shampoos, conditioners and other grooming products should be selected carefully. Select products designed specifically for dogs, and avoid products that are high in detergent, alcohol, silicone or are highly perfumed.
