Alright, you said you wanted an active dog, so I'm going to plead my case one last time. This'll be the last time I pimp my dog out.
He's 3/4 Blue Merle Australian Sheppard and 1/4 Australian Cattle Dog. He's 45lbs full grown. The most loyal dog I have ever had. Eats 2 cups a day.
I'm not a runner but when my little brother was staying with me on leave from the Army he would go running every morning and take Rocky with him. The dog just want's to go go go as you'll see in the link below. He's always by my side and so damn smart.
I know you have an issue with shedding, which he does but it is not as bad as a Golden or a pure bred Aussie because of the Cattle Dog in him.
The breeder we got him from is in Newyago and we actually ran into another pup from the same breeder at the Lake Orion dog park. I think the dogs share a parent.
This is Rocky
This is what we do every weekend
