How can you tell?Awesome, never seen that color. It is a pure bred coyote.
There are others here than im sure have more knowledge than me. It is biologically possible, but very unlikely. Coyotes have a breeding season while domestic dogs have a cycle, and while these two can overlap, the social behavioral differences would make it an extremely rare thing in the wild. However a domestically raised coyote can and would be much more likely to successfully breed with a domestic dog.How can you tell?
