I've had 4 so far. They are fun dogs as long as you remember they are bred to push cattle and think for themselves, so there's always some negotiations as far as who's in charge with an Aussie. They are happy if you are, but will eagerly take the lead if allowed. It's why people have troubles with them. They do best with not too much coddling, and make sure you explain everything to them.
Sunny used to have to take daily pills for various things. She fought me me for weeks until one day I explained what each pill was for, and she let put each in her mouth without clamping shut. So from there forward I explained every day what the pills were for, and she was fine.
I have lots of Aussie stories. They are amazing dogs for the right people.
