In Texas, rednecks pronounce it (ky-ot) with the second "o" being long. Mexicans pronounce it (koy-otay), which also what they call the smuggler that brings them across the border. They earned that name because they are scavengers that will take every penny you have to bring you to America. There's not much vegetation in arctic or sub-arctic areas but there is enough in northern Siberia to sustain reindeer. People in that area would trade with other parts of the asian steppes for other food, such as rice to supplement their diet of fish and seal. I think you are correct in that certain breeds adapt to food from a region where they developed. And true, some canids may tend to eat more meat than vegetable.
So, let's get back to a real hard, bottom line equation in evolution. An animal that can eat more than one food source is likely to survive longer, (possibly, better) than one that tends to eat just one thing. Wild canids live, on average, 4 to 8 years. The number one cause of death appears to be a toss-up between the activities of Man and starvation. Some activities of Man could be counted as predation, i.e., a rancher who lost his cow to a wolf will shoot and kill the wolf, though not eating it. Other scavengers, such as vultures, will take care of that. Other canids, such as the Maned Wolf of South America will eat up to 50% vegetation during the summer, including a preferred berry from a bush named after it. Fruta Lobo, Wolf's Fruit. Just because a certain pack of gray wolves may tend not to eat vegetation and concentrate on meat does not mean that they are not malnourished and that, even with the canid's ability to survive malnutrition for a long time, will not succumb to the malnourishment or pure starvation due to not enough old and sickly prey to catch. Again, evolution is not perfect. It's more a matter of statistics. The more adaptable a species, the greater it's chances of survival. As a species, we are weak and lack natural weapons and we are slow. What makes us the dominant species, amongst other things, is our adaptability, which includes our ability to manipulate our environment, i.e., grow food, build computers and surf an internet.
