My dad did something similar to that to Duke when he was a baby.
I had to leave to go to the store, and I couldn't take him with me. He always had separation anxiety so he would stand by the door and bark when I would leave him behind. My parents think that a dog needs to pee every 15 minutes
and so my dad took it as he needed to go out and I just left...I was starting my car and my dad comes out, Duke was standing in the grass and I look over and my dad yanks him up with the leash choking him with his collar
I was livid.
I don't think anyone should pick up a dog like that no matter it's size. It's just not ok.
