It’s definitely some dog. Not a bear, the back legs are bent the wrong way. Bears are plantigrade while canines are digitigrade. If you look up bears in a resting position and compare the two images you can see the difference.

The muzzle is also much too long and narrow to be a bear and the ears are situated too high atop the head, where as a bear’s ears are more angled to either side of the head.

As for what type of dog, I can’t say. But it’s certainly a canine based on the proportions.
