Wow, just wow. What a little trooper! This little gal can even melt a heart made of stone!
They need to get that little dog her cart ASAP. She will wind up wearing holes in her chest and the bottom of her jaw if they don't get her one soon. As she gets a little older she's gonna get more active!
I've seen dogs with carts before, and most of the time they take to em like a duck to water and never look back. It's very touching and rewarding to see em wheeling around like greased lightening when they could hardly get around at all before.
