Man's best friend

Ya so we got a puppy a few months ago his name is Johnny Cash.
He is an Australian Shepherd known as a Black Tri because he is black with white and copper markings. He's 8 months and still a handful. He will put ANYTHING in his mouth and eat it before you know it. So we are always yelling "Get that out of you mouth!" or "what is in your mouth now!" He still chases our cat all the time... It is amazing he has survived thus far I keep telling him we only put up with him because he is so cute, but the second he gets ugly he is out on the street;)...
I love that I get to take him to work almost every day, it makes for a lot of bonding time. I am amazed how SMART he is and how much he has grown. We were away from him for almost 3 weeks during his little puppy stage so we missed out a little but he is still growing like a weed. He was at last vet visit 40 pounds and is now at least 45 or more, he should get to around 60 to 65 though. He is a lot of fun and has WAY to much energy but we love him lots...
