So I've had my Corgi Lilly since she was a pup (she'll be 5 in November) and our living arrangements have changed a lot over the years. I crated her until she was potty trained, and then she seemed more or less alright behavior-wise with the run of the house. However, she has taken to ripping up the carpet by the front door when I leave the house. This is unacceptable, as I live in a rental. I tried walking/playing with her, and not acknowledging her when I leave, as well as leaving music playing when I go. She's fine most of the time but every now and then she'll have a fit, for seemingly no reason at all. I've considered crating her, but I work full-time and go to school full-time, so I'm not comfortable leaving her pinned in for 8 hours at a time. Suggestions?
