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.[41] The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled.[42] Compared with equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.[43]:35 The teeth of gray wolves are also proportionately larger than those of dogs.[44] Dogs have a more domed forehead and a distinctive "stop" between forehead and nose.[45] The temporalis muscle that closes the jaws is more robust in wolves.[5]:p158 Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs that had them.[46] Most dogs lack a functioning pre-caudal gland and enter estrus twice yearly, unlike gray wolves which only do so once a year.[47] So-called primitive dogs such as dingoes and Basenjis retain the yearly estrus cycle.[48]
Dogs bear their litters roughly 58 to 68 days after fertilization,[17][71] with an average of 63 days, although the length of gestation can vary. An average litter consists of about six puppies,[72] though this number may vary widely based on the breed of dog. In general, toy dogs produce from one to four puppies in each litter, while much larger breeds may average as many as twelve.
Dogs demonstrate a theory of mind by engaging in deception[89]. An experimental study showed compelling evidence that Australian dingos can outperform domestic dogs in non-social problem-solving, indicating that domestic dogs may have lost much of their original problem-solving abilities once they joined humans.[90] Another study indicated that after undergoing training to solve a simple manipulation task, dogs that are faced with an insoluble version of the same problem look at the human, while socialized wolves do not.[91] Modern domestic dogs use humans to solve their problems for them.[92][93]

Run shower with lukewarm water. Hot water can harm your dog's skin, especially if your dog is short haired. Avoid running water right away on the dog, as it may cause unnecessary stress and burns if starts out hot without checking first. You may have to spend some time desensitizing your dog to the sound of running water with the help of his favourite treats. Always go slowly to avoid overwhelming your pet and making things worse for both of you. If you only have a tub and no shower, use a hose outside as filling a tub with water or only have a cup to run over the dog with water will not penetrate the fur or completely rinse off shampoo properly which causes infection as well as dry skin if completely soaked in water. This is true for even short hair dogs like pit bulls, you don't need the high power setting of any hose only enough to not hurt or stress the dog but still gets the job done.
