Scarlett is maybe 40 pounds. I don't have a real number. She's about three inches shorter than my 54 pounder and a lot smaller body wise.
Her and Emily did tolerate one another but in the shelter environment, Scarlett is a demon around other dogs. Her only real vice is the leash tugging (tugging is a nice way to put it, I can't really explain it). It makes it really difficult to walk her. I've been trying to work with her on it. She can sit, down, shake, high five, half way roll over. She is VERY clingy. She wants to be with you at all times. When I walked away, she screamed.
She really just needs a job. I'll post some pics up of her weekend with me. She loved the spring pole and flirt pole most. She is very respectful when it comes to human food. When she first came in, she was skinny and food aggressive. We stopped by Subway the other morning and she waited patiently until I was ready to give her the pieces of egg. We stayed in the truck for two hours yesterday and all she did was sleep on my lap. She rides very well in a vehicle. Very respectful of most everything human related. She hasn't had her safer test done yet, but I've messes with her mouth, feet, tail, etc and she didn't mind at all.
Over all, she's a great dog. The other shelter employees were shocked when I described our weekend because she just doesn't act that way in the shelter. I really want her to have a chance but I've kind of been shielding myself just in case the board decides to euthanize her too. I really don't want to get attached but it is too late.
