I have had two Shelties. One was a sweet girl who had some issues (due to poor breeding) and the other was my heart dog. He was perfection.
I get kind of emotional around Shelties since losing my boy a year and a half ago, so I probably won't have another. But man, he was awesome. My girl was pretty great too (don't want to sell her short!)
I had a Lab/BC mix and that's probably as close as I ever want to get to having a BC, haha.
I've seen the picture of your boy and he's a handsome fella. Good that he's got a great home - and I'm sure you'll just fall more and more in love with him!
