Keesha was my 1st Aussie. I purchased her for $25 while attending graduate school in Wyoming; she was purebred but unregistered--her parents worked stock at the local slaughterhouse for a living. As the saying goes, you get what you pay for. I could not have asked for a better companion--she loved to go trail riding, would play fetch all day or just hang out. However Keesha was dog aggressive--you never knew what might set her off in her younger days. As Keesha grew older and became more arthritic, it was usually a bump from another more exuberant dog that would set her off. Just learning how to cope and manage her was stressful but worth it. Having lived with a dog like Keesha has caused me to make good, sound temperaments a high priority in my breeding program.
