Pet grooming refers to both the hygienic care and cleaning of a pet at home, as well as a process by which a pet's physical appearance is enhanced for showing or other types of competition. A pet groomer (or simply "groomer") is a person who earns their living grooming pets. The most basic and obvious job that a groomer performs is bathing the animals. They use special equipment and soaps in order to clean animals safely and comfortably. In addition to bathing pets, groomers also trim the pets' fur and nails. Since animal fur and nails have a different anatomy than a human hair and nails, this requires special tools and training in order to perform these functions safely. Groomers must also know different traditional grooming styles that are popular with different breeds of animals. These styles are often too complicated and time-consuming for pet owners to perform properly, so they must turn to a pet groomer for help. Pet groomers will see each pet once every few weeks to make sure they're kept clean and happy. Since grooming requires a vast amount of special tools and equipment, animals must usually be brought into the veterinary in order to be groomed. Some groomers, however, can set up their equipment in a large van or truck in order to be able to go door-to-door with their grooming business. Grooming for dogs is a vital part in the well-being and healthiness of a dog which can improve their lifespan. All Breeds require daily grooming, how much depends on the breed, age, or health of the pet. Regular grooming helps to ensure the dog is healthy and comfortable. It is important to note that while many dogs shed, others (such as the Poodle), do not shed (see Moult) as profusely, and require grooming by a professional every 6–8 weeks maximum.
