It's the new toy in the backyard so they both need to claim it everytime they go out. Thankfully nobody has 'made it official' yet.see an electric wire in your future!
But hopefully they tire of it and move onto the next thing. Maybe I'll plant a tree so that they'll have to run out to sniff that each time instead.
Tentatively if it's an ongoing issue I am going to make a string fence for the few months the cover is on. Both dogs do great with mental barriers, providing there is no bunny rabbit on the other side of the bogus barrier.
