At least we're not the only ones who see it, read the comments. EVERY. SINGLE. ONE. is saying the exact same thing!
What a good dog that is, to exhibit such restraint in what is obviously a very uncomfortable position for him. Judging by the scars on his face, he didn't come from a good situation, yet still has a good temperament. I really REALLY hope that particular rescue saw this, wasn't brain-dead to the point of having the poor dog PTS for "growling" and revoked that woman's fostering status.
