Growls and Snaps... and Cats

Hello - I have a male Mini Aussie that just turned 2 in November 1st. Xander is a GREAT, loving dog... bit of a freak about our cats but we are working on that (any suggestions on this would be greatly appreciated as well...). My reason for posting is we are having some aggression issues in the last week or so. Now not the kind when he is playing with our 1 yr old Boxer Maddox (I call him Fathead, largest head I've ever seen on a dog), it's actually toward our 12 yr old daughter. Now he hasn't bitten her or anything but for some reason, at times he will growl and lunge at her and sometimes snap... it's not anything specific she does, one time she will be getting up off the couch and another will be when she gets something out of the cabinet and then sometimes not at all. This is a behavior that needs to be corrected before it gets worse, and I don't want to handle it in the wrong way and make it worse... anyone have any ideas why this has just started happening,and/or what to do to correct it??

Thanks
Windy
