I keep a friend's dog, Mickey, in the mornings until she can go to a third friend's store for the rest of the day. The reason is if left alone, Mickey will attempt to go through doors and, barring that, eats the wooden door frames, furniture legs and couch pillows. She's like an enthusiastic beaver with a feather fetish. I love having her in the mornings, but I'm off to Spain in three weeks, so Mickey will once again be alone in the mornings for an hour. Yes, that's it...only an hour alone and she goes completely nutballs. She's not even technically alone, as her human has three other dogs and five cats who are also in the apartment. Out of desperation (she's replaced her doors/woodwork several times at this point), my friend recently got a crate for the first time and I've offered to help crate train Mickey while she is with me in the mornings. My idea was to go VERY slowly - door open for a week, then closing the door for a couple minutes at a time with me in the room, then doing the same but stepping out of the apartment very briefly and slowly building up time, etc.. However, my friend doesn't want to bother bringing the crate over (I understand, as it is heavy and she lives on the 4th floor with no lift). I suggested buying a temporary fabric crate but she doesn't want the extra expense, which I also understand. Does anyone have any suggestions about how I can help Mickey with this behaviour in the three weeks I have left with her? I've thought about maybe building a little "fort" out of kitchen chairs and some sheets with the idea that this might be kind of crate-like. But I've also thought that this would simply be an exercise in Mickey laughing her doggie head off at me. By the way, she is an adult (8-12 years old) very smart medium sized (20kg) ex-street dog. She gets lots of walks and a ton of love, but little actual training and mental stimulation beyond the walks. I've worked with her on leash dog aggression and taught her some basic obedience stuff - she learns very quickly. Any ideas on training to solve the beaver behaviour? Here's Mickey (big one) and Fritzi (little one).
