The evidence that it could be either a coy-dog or a black coyote is easily acceptable to me. The bottom line is that it is of the coyote family. Get yourself some calls and have some fun.
Here is one that I called in about 5:30 tonight. It is on the smallish side, 32 pounds. It is a young male that I called in with a combination ofdying rabbit squeals and coyote howls. Slightly over 120 yards; a chipshot for most gunners. He couldn't figure out what I was in the camo. I was sitting in a grassy terrace.
