I've shot lots of coyote and plenty of dogs. Don't think I'd ever called in a dog whether it was day or night. Like mentioned before, I think it'd be pretty easy to tell a dog and 'yote apart if a person pays attention before pulling the trigger. Mannerisms, body language, etc. are noticeably different. I know a person oughtta know what their shooting at but admittedly, I did chuckle at the sight of the "wolf pup" above. Before y'all go to bashing me on shooting dogs, know that I did not mistake them for coyotes or "wolf pups", they were all strays, drop-offs or town dogs that wandered too far from town and got to chasing cattle and/or horses. Every one I ever shot was not the first time I'd seen them either. I give them all a chance of staying gone after running them off but if they become repeat offenders, they are dealt with. I don't care to shoot a dog and would rather make friends with it and give it away but cattle and horses is what pays bills and feeds the family so no, I won't give them a third chance.
