HI! We just adopted a dog back in May and he will be a year old this month. Imagine a mid size dog, black all over except on his chest , under his chi, and a spot on one foot. We think he is a black lab, border collie, australian cattle dog, and australian shepherd mix. His name is Kelty and my husband nicknamed him Muttly. We taught him sit, stay, shake, wave, down , and off. He is a bear on the head halter, still trying to loose leash him, come, his name which he ignores sometimes, and he likes to jump our 3 1/2 foot fence. Still working on the barking which he does to squirrels a lot and when he is in his run.
