Yeah, no kidding. I had that same issue with the dog nextdoor. They tried that invisible fence first. Either the batteries in the collar didn't work or he'd just run over the line and definitely did not want to go back through it and be zapped again. I just don't like those fences. One problem is that they require maintenance and attention from the owner. I feel like some owners just think, "Problem solved!" and forget about it. It doesn't keep dogs from coming into the yard and luring the collared dog out or some person coming onto the property and being possibly bitten.
So, lots of issues with invisible fencing if someone doesn't take care to be sure it's working properly. but these owners have apparently been told about their dog and we'll have to get an update from junkman to see if they paid attention. The bear would worry me, too! I just watched the movie, "Backcountry" from 2014 where a camper was eaten by a black bear then I come and see these pictures, LOL!
well I have not caught the dog on camera since I told the dog owners that their dog been at my coop, so I guess they fixed the problem with the invisible fence or collar, ( I hope so ) I do have a pellet rifle next to the door now, as for the black bear, bear hunting season as just passed so I hope he wont be around anymore. he visited us twice, but not lately, and it is soon to be hibernation time also.
thanks for your responses
