I had a dog that did that. She hid her bones and toys under the sofa cushions and dug holes outside to hide whatever she found. I caught her trying to bury my rake one day and it took weeks to find the bottle of window cleaner that I set on the ground while I was cleaning my car windows (she buried it).
He`s obviously a "Hoarder" lol...no my daughter did that...anything she could fit into the cold air return vent..in it would go.. coins..earrings. etc
Mine did too- it's hilarious. Enjoy it before s/he starts hiding weed
Hahaha, first child?
