Dogs are highly variable in height and weight. The smallest known adult dog was a Yorkshire Terrier, that stood only 6.3 cm (2.5 in) at the shoulder, 9.5 cm (3.7 in) in length along the head-and-body, and weighed only 113 grams (4.0 oz). The largest known dog was an English Mastiff which weighed 155.6 kg (343 lb) and was 250 cm (98 in) from the snout to the tail.[31] The tallest dog is a Great Dane that stands 106.7 cm (42.0 in) at the shoulder.[32]
Citing a 2008 study, the U.S. Center for Disease Control estimated in 2015 that 4.5 million people in the USA are bitten by dogs each year.[176] A 2015 study estimated that 1.8% of the U.S. population is bitten each year.[177] In the 1980s and 1990s the US averaged 17 fatalities per year, while since 2007 this has increased to an average of 31.[178] 77% of dog bites are from the pet of family or friends, and 50% of attacks occur on the property of the dog's legal owner.[178]

Clip the dog's hair methodically.[9] You can place the blade against the body safely, so long as you don't press the blade strongly into the skin. Brush against the direction of hair growth(back-brush) before running the clippers the other direction; with the direction of hair growth. Using the clippers against the growth of hair will have the same effect as back-brushing, but will leave a shorter length than the clipper blade that you are using. If you want to shave against the growth of hair, a blade size gets two blade sizes smaller when cutting against the grain. For example, when cutting with 4# against the grain check how long a 7# leaves behind when cutting with the grain. Move the clippers surely, but slowly across the dog's body to remove the hair — moving too fast might leave uneven lines. Always move the blade with the direction of the hairs' growth unless you want a shorter length than your blade claims to leave. Begin at the neck, then move down to the shoulders, under the ears, and toward the chin, throat, and chest areas. DO NOT use a size seven or any skip blades around the throat area or any flaps on the body that can fit between the teeth, such as the Achilles' tendons, arm pits, genital area, tip of tail, or anus. Then, clip the dog's back and sides. Finally, clip the hair on the dog's legs. Be careful when cutting the neck with any blade as it's the most dangerous to cut. Never cut straight down, do so at angles to avoid flaps you can't see in the neck getting cut.

Comb out your dog first.[1] 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.

Do you have a dog that you get groomed regularly? If you do, you’ve probably wondered how much — or even if — you’re supposed to tip your dog groomer. Treat your dog groomer as you would your own hair stylist. A 15 percent to 20 percent tip is an appropriate amount to show your appreciation for a dog grooming job well done. If your dog didn’t get clean or their nails didn’t get properly clipped, then you certainly don’t have to tip. But if you’re satisfied with the service, consider the tip part of the standard dog grooming price, and just plan it into your dog care budget so you’ll have a happy groomer and a well-groomed dog. Here are a few examples of when you should tip extra:
Clip the dog's nails.[3] 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. [4]
In conformation shows, also referred to as breed shows, a judge familiar with the specific dog breed evaluates individual purebred dogs for conformity with their established breed type as described in the breed standard. As the breed standard only deals with the externally observable qualities of the dog (such as appearance, movement, and temperament), separately tested qualities (such as ability or health) are not part of the judging in conformation shows.
The domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species)[5] is a member of the genus Canis (canines), which forms part of the wolf-like canids,[6] and is the most widely abundant terrestrial carnivore.[7][8][9][10][11] The dog and the extant gray wolf are sister taxa[12][13][14] as modern wolves are not closely related to the wolves that were first domesticated,[13][14] which implies that the direct ancestor of the dog is extinct.[15] The dog was the first species to be domesticated[14][16] and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes.[17]
Pets with special needs: Our salon safety protocol is maintained to the highest safety standards. Express service is available for pets who prefer to be hand dried only. For pets with flatter faces (also known as brachycephalic), your stylist will recommend this option as this will greatly decrease the amount of time your pet will spend in the grooming salon, and may be a better option for the health of certain breeds. Please note that we cannot accept wolf hybrids at this time, due to vaccination limitations.
