One of my sisters has an Old English Sheepdog named Jake. What a love, except when he gets stubborn. About a month back, she wanted to go one way, he the other. Given that he outweighs her, down she went. Ended up with a broken leg.
When we showed up to take her to the hospital, here's this really pitiful face in the sliding door with a look of "what did I do?!" He spent the night outside on the porch (don't worry, it was warm night and a fenced in yard). I think another round of doggy training is in his future, as soon as she gets off crutches. Gotta love him!
