We bought our one year old, Leisel, a dog house for Christmas. I think it is the greatest thing ever, but she is reluctant about going all the way in. I've tried putting trats in the far corners, but she stretches as far as she can, gets the treat without entering the house completely, then slinks off to chew it up! Any advice on how to encourage her to use it? I thoug tabout slathering the walls with peanut butter so she would stand in there, licking it off....
