I had a friend with a black lab. One July 4, the dog was so disturbed she jumped through a big glass picture window, trying to get away. They had to track her down, and get a new window :-)
Otter is 120lbs of dumb, I tell people he’s half black lab, half water buffalo (we think it’s great dane) but MAN can he play frisbee, gentle, loves hugs, snuck up on a neighbor last year while she was in her garage and licked her hand, got scared and ran off when she turned to pet him; he will run out the door in a heartbeat if you give him half a chance, which is rare.
