Pembroke Welsh Corgi. (But pretty much any dog that will catch a frisbee)
My mom is into Blue Heelers. I think the ones my mom breeds are miniatures though.. They are shorter than most heelers, a darker blue with barely if any grey. The only markings are their full black masks with brown dots on their cheeks and eyebrows, brown inner ear, sides of the mouth, chest, and paws. (Like the 2nd pic, except a darker coat)
My dad is into Brittany's, and likes to hunt.
I'll post some pics of our dogs, and blue heeler puppies if I find my brothers camera.
