Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel electrophoresis of red blood cell acid phosphatase. The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled. Compared with equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.:35 The teeth of gray wolves are also proportionately larger than those of dogs. Dogs have a more domed forehead and a distinctive "stop" between forehead and nose. The temporalis muscle that closes the jaws is more robust in wolves.:p158 Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs that had them. Most dogs lack a functioning pre-caudal gland and enter estrus twice yearly, unlike gray wolves which only do so once a year. So-called primitive dogs such as dingoes and Basenjis retain the yearly estrus cycle.
Clear the dog's eyes. White-haired breeds or those with large eyes that water a lot (Pekingese, Pugs, Pomeranians, etc.) may need more maintenance in this area than others. Depending on your particular dog, this step may be a simple matter of wiping or pulling eye debris away from the corners of the eyes. Long-haired or white-haired dogs may need special attention to make sure that all gunk is out of the coat, as they may get tear stains. You can buy products made for removing "tear stains" from a white coat at a pet supply store.

As humans became more sophisticated, so did their dogs. Eventually, there emerged specific breeds of dogs, custom-bred to suit the breeders’ local needs and circumstances. The Greyhound, for instance, was the foundation type for the immense Irish Wolfhound and the dainty Italian Greyhound. All three have a distinct family resemblance, but you’d never mistake one for another.
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. A 2015 study estimated that 1.8% of the U.S. population is bitten each year. In the 1980s and 1990s the US averaged 17 fatalities per year, while since 2007 this has increased to an average of 31. 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.
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.
