This is so weird to even contemplate breeding a spayed mutt when I am 100% never ever going to breed a dog! But, just for fun...Lucy is smart as heck, drivey as all get out, structurally very sound, and rapidly progressing through agility titles.
That said, she is a reactive little brat on leash, and can't eat hardly anything without having cannon butt. There are zillions of mixes in the shelter who are also smart and drivey, structurally sound, and agility potentials. As much as I want a Lucy clone one day, I would never breed her.
If someone gave me a puppy Lucy though, I'd take it in a heartbeat.
