My sister and I adopted a three year old boxer named "Princess Gigi". She was found tied to the side of a barn eating rocks and siding off the barn. The barn of course was a puppy mill. So they rescued her and Stacy, the lady we got her from fostered her. When we first saw her we knew she was supposed to be with us. We took her home. First we dropped Princess Gigi for Elvis. Her lower jaw bone is crooked, apparently this is common in boxers, so any way her tounge hangs out slightly and her lip curls up, hence Elvis.
When she first got home, she wouldn't eat or drink or play or really do anything but cower away from us. So we gave her her space and eventually she came around. She was about twenty pounds under weight when we got her. I am happy to report that she is now at her target weight, she eats, drinks, plays (a lot), and has completely changed our life. She doesn't need a leed when we walk her or even just let her outside, she doesn't even WANT to be away from us. She is great with my neice. Elvis is a super dog. She is a love bug and I am okay with that, I am happy to have her around and love her a lot.
This brings me to my point. I get ill when I hear stories like this. About people who do these things to these poor animals. I am ashamed to breathe the same air as them. Why would you treat a dog, a cat, a horse, or ANY other living creature in this way? They can't fend for themselves, might as well tie a baby to the side of the barn for god sakes...
