The Tundra wolf (Canis lupus albus) (not to be confused with the Alaskan Tundra wolf)lives in the North of Europe and Asia, especially in the arctic and northern parts of Russia. Their fur is usually light and grey in colour. The lower fur is lead-grey and the upper fur is reddish-grey. Two main types of the general light color tone are found: light-gray with reddish shade and bluish-gray without this shade. The colour of their coat changes noticeably during the course of the winter.[x] Their fur is very long, dense, fluffy and soft, and a Tundra wolf pelt therefore brings up double the money than other wolf pelts.[x]
Some main differences with the Arctic wolf and Tundra wolf: The Arctic wolf (Canis lupus arctos) lives in the North of North-America. The coat of an Arctic wolf is always a creamy white. In general, an Arctic wolf’s nuzzle is smaller and rounder, and has a narrower braincase.
It’s extremely difficult to find pictures of Tundra wolves, because many people confuse the Arctic wolf, Tundra wolf, and the Alaskan Tundra wolf. Searching pictures of them online leaves me so confused, lol.
Wolves have a wider, more varied diet than dogs, and can digest more kinds of foods. Grapes for example are a normal part of a wild wolf’s diet (though if wolves have the change between fruit and meat, they will choose meat).
Garlic isn’t per definition poisonous for dogs - for example garlic is sometimes used against fleas, and only a big amount is harmful. I assume it neither is for wolves (I don’t have a legit source for this).
But like dogs, wolves lack the metabolizing enzymes that break down the theobromine and caffeine in chocolate, so that is poisonous for wolves as well.
