The longest-lived breeds, including toy poodles, Japanese spitz, Border terriers, and Tibetan spaniels, have median longevities of 14 to 15 years. The median longevity of mixed-breed dogs, taken as an average of all sizes, is one or more years longer than that of purebred dogs when all breeds are averaged. The longest-lived dog was "Bluey", an Australian Cattle Dog who died in 1939 at 29.5 years of age.
Wolves, and their dog descendants, likely derived significant benefits from living in human camps – more safety, more reliable food, lesser caloric needs, and more chance to breed. They would have benefited from humans' upright gait that gives them larger range over which to see potential predators and prey, as well as better color vision that, at least by day, gives humans better visual discrimination. Camp dogs would also have benefited from human tool use, as in bringing down larger prey and controlling fire for a range of purposes.
Please note that regardless of pet type, we always put safety first. Sometimes pets can stress in new situations. If we feel your pet is too stressed or showing any potential health concern, we may opt to conclude the grooming appointment in order to do what's best for them. Your stylist can help recommend a grooming service for a smooth introduction, such as a Mini Make-Rover. For any potential health concern your stylist will refer you to your veterinarian.
