We’ve always been able to let Blazer out when he needs to make a puddle (or anything else) and he will bark to come back inside.
A couple of days ago we discovered him out in the back yard, cavorting with a coyote. I put him out last night, and he barked to come in pretty quickly. When I didn’t hot-foot it to the door, he began barking again, almost frantically. When I looked outside there was not one, but two coyotes out by the barn! No wonder Blazer wanted Momma to rescue him.
I think we’ll take the ol’ puppy for a walk at night, rather than let him have the run of the yard. We’re also going to stop feeding anybody out by the barn. No point in tempting fate.

I don’t know if you are aware of it, but coyotes will eat small pets. January through March is breeding seson for coyotes and they will attack larger dogs if they feel their territory is threatened.
Glad he’s okay.
Thanks! We’re pretty happy he’s OK, too. He’s a good sized dog, but if two coyotes decide to gang up on him, it won’t be pretty.
