Had a aussie mix years ago, great dog.
In the last 23 years, I've owned 5 dogs - Aussie, Rottweiler, Greyhound, Jack Russell, and Yorkie. Hell, everyone of them have been really good dogs.
Tried to rescue an Aussie mix recently and damn if rescues aren't a pain to deal with now, they told us adopting a dog is harder than adopting a kid.
