The first picture, although not quite clear, appears to be squirrel tracks. I found similar tracks in various locations, not just in my place. The pattern seemed to resemble the likes of a galloper which is a characteristic of the gray squirrel. Gallopers land with their hind feet ahead of their front feet.
The second picture is more clear cut. It can be characterized as a dog because of the claw prints and the measurements most closely matched those of a dog. The print measured close to 4 inches which is about double that of most other “dog-like” animals such as the coyote, gray fox, and red fox.
