What Are Some Good Mentally Stimulating Toys For My 18 Month Aussie?
What are some good mentally stimulating toys for my 18 month Aussie? We already have the Kong, and several Frisbee's, balls, and empty water bottle stuffed toys; what I'm looking for are some toys that are durable yet mentally challenging for our Aussie. She's bright and energetic and we need some new ideas to keep her entertained. We live in an climate that can get extremely hot (100+ deg's during the day) and taking her on all our errands just isn't practical or safe.
