I've seen them lay like this but not SIT like that. This is my parents Miniature Schnauzer, Mr. T.
I got him for them after the shelter dog they adopted passed away due to old age. A friend had him and didn't take care of him very well. He'd never had a vaccine and he was a year and a half old...I vaccinated him and they got his rabies vacc. and neutered him.
The only true wisdom is in knowing you know nothing.
