How to identify cougar, coyote and bobcat tracks
First, determine if the track is from a canine (dog) or feline (cat). Canine tracks have definite claw marks, one lobe on the front of the heel pad, and two lobes on the rear of the heel pad. In contrast, feline tracks rarely show claw marks, the front of the heel pad has two lobes, and the rear of the heel pad has three lobes. Canine tracks are typically rectangular in shape (longer than they are wide), while feline tracks have more of a square or circular shape (length and width are even or track is wider than it is tall).

Then look at the size of the track adult cougar tracks average 3 1/2 inches tall by 4 inches wide. In contrast, coyote (and most other dog) tracks are longer than they are wide. Bobcat tracks are much smaller than cougar tracks, typically about 1 1/2 inches long by 1 3/8 inches wide.
