This is for fun, but I'm curious to what the experts might see in this girl. This is a totally natural stack... I think. Meaning I did nothing for it. She is my husband's dog and he is working with a very good trainer who sees working line characteristics. She is big boned. Strong as a linebacker and very fast and powerful. We rescued her and it was reported that she is around 2-3 years old, had recently had pups, though none were found with her and she was picked up as a stray in a rural area. She is about 70 lbs and it is tough to put weight on her. I think she could use 3-5 lbs very very thin although you can see that in the pics. Just curious.
