Periodic pet grooming also keeps certain cosmetic issues from turning into genuinely painful problems. For instance, clumps of matted hair can pull agonizingly on the skin, making a simple brushing impossible, while also encouraging skin oils and infectious bacteria to accumulate. Overgrown toenails can get caught on carpet fibers or flooring, tearing the nail right out of the nail bed. A blocked anal gland can become infected and develop an abscess. Regular “maintenance” through cat and dog grooming sessions can prevent such unpleasant outcomes, giving you a happier, healthier pet.
