Go ahead and call animal control on the hope that you were given the correct address~ but probably the address offered will not be the address where the animal is actually located......who in their right mind would admit to having that animal in thier care, refusing medical care to it, and offer their address to concerned strangers? But call them just to cover all the bases.

It's sad~ but that animal needs to be destroyed. I know there is a "Chance" and all that~ but it's highly unlikely that wound would heal~ even with extensive vet care..............

The kindest thing would be to destroy it~ if whoever has it is reading this~
