I'm fostering a 18 month old female Malinois for the national rescue. Just picked her up from Kansas City yesterday. She's been living on and off at a vet clinic for the last 6 months. She was bred too young and developed "fibrocautalagenous thrombus cervical vertebrae" during the end of her pregnancy. I don't have a vet Merck manual handy so I'm not sure what exactly that entails, but it sounds somewhat similar to a deep vein thrombosis in pregnant women. Her breeder didn't want the prospective puppy buyers to see her limping around and so wanted her put her to sleep. The vet wouldn't do it. She still has a slight limp, but gets around pretty well otherwise. Haven't tested her much for drive, but sport or agility probably wouldn't work because of the limp. I might start her on tracking and see if she likes it. She met some kids and other dogs today and did great. She's not super intense, crates well, is quiet, and settles well in the house, and would probably do well with a fairly active pet home. I can take more pictures if anyone is interested.
