I have two dogs, a Chi-Aussie mix that looks like a red heeler-min pin cross, and an Aussie mix that has shepherd body-shape and coat any Kelpie coloring. They both like to play rough with eachother, but they are pretty good at playing gentle with people. They will lightly nibble on my hand if I scurry it along the floor, then when they get bored playing with me, they will chomp on eachother and then ZOOM around the house like wild things! Most of all, they love to snuggle especially on cold winter nights.
