That is one weird looking animal- I can't tell what it is!
Foxes are nowhere near as big as large labs. Doesn't look coyote, or cat, or even dog.

We have a whole family of poor mangy red foxes in our neighborhood lately- apparently the mother was injured and her adolescent cubs all scattered about into people's yards, including ours. Mostly they're being left alone to wander off and find homes somewhere. Today my neighbor told me she saw a 3 legged fox go up our driveway. It's been guessed that they don't have rabies, but are mangy. Poor things.
