I go out to feed my dog sissy and knowing that she is hyper I am trying to protect my shoulder. She jumps and I protect my shoulder, but she connects where men are not supposed to be kicked.
Trust me she is in no danger of starving or going hungry. She is just real hyper. I got her from a resue outfit as she was abused as a puppy. She is really sweet, she just thinks that if I am in the backyard that it's playtime.
She can probably understand that something isn't right (your shoulder), but I doubt she really gets that you aren't quite up to snuff. I'm a total softie when it comes to animals.
