That is one spooky dog! Yeah - I wouldn’t tease it.
And I don’t consider it teasing, but “training” when I put the dog dish down and our dog has to wait for an “okay” to start chowing down. And then - I’ll take the bowl away for 15 seconds and he sits and waits patiently for it back again.
Although my wife thinks I’m weird when I get down on all fours and pretend to eat out of the bowl, pushing the dog’s head away with mine. Lab/mutt and a real good demeanor.
Except for certain folks that come to the door. And as mentioned up-thread, he is a real good judge of character. Weird how two adult brothers that look and dress similar get such a different reaction. But we know that one is not the highest of character, and our dog can’t stand him!
