Hi Natalie - a lady of taste & discernment :D :D
We too have Aussies - started with 1, and now have 4!!!
They are lovely dogs - very noisy, I have to admit, and the one thing that I would advise you to do is socialise, socialise, socialise - and then SOCIALISE!!! From the minute that you bring your puppy home, take it out, let it experience as much as is possible. Believe me, it will definitely pay off.
They are very busy dogs - but they aren't as "off the wall" as border collies can be, if there is a day when you cannot work/play with them. We have found that they aren't as keen on playing ball as our labradors are - if we throw a ball away - then obviously, we don't want it - so why on earth should they bring ig back to us ?? :D
They are little wriggle bums, and will stick as close as possible to you - I can easily be tripped up by 2 or three of them, all trying to walk as close to me as possible! Be prepared to be kissed on the ears

by your dog when he is fully grown - they all LEAP into the air with joy when you appear - and as for the Aussie grin :) :) - they always look soo happy to see you!
Do let us know more about yours when you get him/her!
Regards
Margot
