Comb out your dog first. Combing your dog's coat daily or every other day will keep most mats at bay. Simply brushing, as most literature instructs, is not enough for dogs that can mat up: the brush will easily pass over at angles that a comb will get stuck on. A thorough combing should always be the first step of the grooming process because any mats will become tighter and less manageable once they dry. Begin on the head and move down the body. Be careful under the belly, as it is a sensitive area, and don't forget to comb the tail.
Clip the dog's nails. If left untrimmed, a dog's nails can curl under into the paw pads or twist toes in a way that causes joint damage. To keep your dog's nails short, clip them regularly, depending on how fast his nails grow. If you can hear his nails on the ground when he walks, that means his nails are touching the ground, and are too long. 
Dry your dog. Use a squeegee or use your hand as a squeegee to force water off of the coat and body. Towel dry him as best as you can while he's still in the tub, so you don't make a mess. Place the towel over your dog’s back, or hold it next to him and give permission to shake the water off their body. Many dogs will learn the “bath rules” and wait to shake until you have placed the towel over them to contain the water droplets. Another type of towel to use is a chamois, which is a thin fleece like towel that is designed to be wrung out when wet. It lessens the amount of towels needed and does the bulk of the work. Using a chamois, then a towel makes drying less of a hassle.
In 1999, a study of mitochondrial DNA indicated that the domestic dog may have originated from multiple grey wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other. In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed under the wolf Canis lupus its wild subspecies, and proposed two additional subspecies: "familiaris Linneaus, 1758 [domestic dog]" and "dingo Meyer, 1793 [domestic dog]". Wozencraft included hallstromi – the New Guinea singing dog – as a taxonomic synonym for the dingo. Wozencraft referred to the mDNA study as one of the guides in forming his decision. The inclusion of familiaris and dingo under a "domestic dog" clade has been noted by other mammalogists. This classification by Wozencraft is debated among zoologists.

Dog grooming also includes hygiene services such as toothbrushing and ear cleaning. Clean teeth are important to the health of your dog, and the pros have the patience and proper technique to get it done. Regular dog grooming can stave off tear stains, those reddish stains below your dog’s eyes. Anal gland expression is something not many people want to do on their own, even if they love their dog. A dog groomer can safely and efficiently release any blocked anal gland fluid. Other dog grooming services include nail trimming and clipping. Nationally, dog grooming prices range from $60 to $80. Most dog groomers offer discounts to customers who purchase monthly packages or bundle multiple grooming services at one time.
Experienced pet stylists hired from outside the company must complete a personal skill evaluation by a Petco Certified Pet Stylist or Grooming Salon Leader, as well as four weeks of safety and pet grooming operations training. They must also complete and pass a technical skills assessment within 14 days of hire. If the candidate does not pass the technical evaluations, they must complete Petco's 12-week Pet Stylist Apprentice & Certification program and retake the skills assessment.
