Max is 14 months old, an Aussie/Collie mix. We adopted him about 3 weeks ago.
He's so weird...he chews things, but he also just takes stuff outside. Weird stuff. The other night, it was potatoes. Then mangoes. One night it was all of the shoes from my kids' closet. Luckily, he doesn't destroy them (usually). He did chew up my daughter's potty seat, and a sandal - but mostly, he just takes it outside.
My husband says maybe he's herding - but who knew dogs wanted to herd mangoes, potatoes, or shoes?
