I got to meet the parents' dog in person yesterday...I'm now strongly leaning towards GSD/border collie mix since I've met her in person. She is narrower than she looked in the picture. She's EXTREMELY prey driven. She's also, unfortunately, pretty reactive to other dogs. I'm not too happy with the rescue they adopted from - on "paper" this dog should never have been adopted out to my parents. Thankfully they have a decent support network with skills to help them, and I'm hoping she will be "workable" and able to make enough progress to be able to take walks, etc....but I hate seeing this kind of stuff - it's becoming far too common with too many rescues. Not nearly enough behavioral screening, not properly matching dogs to the right homes....argh. It just really irks me. Plus, this dog isn't really at all suited to their lifestyle (again "on paper") - thankfully, they are reasonably willing to "step it up" and put in the work, but....not the type of adolescent that should have been placed with them. I'm not taking all the responsibility off them - I wish they had put in some kind of work to figure out what they needed in a dog and what was a good fit, but....as pretty average pet owners, this is what happens far too often.
