I have a 22 month old female. We started crate training her as soon as we got her at 10 weeks. At 1 year we started giving her a little more freedom but crated her while we were at work. In January I stopped working and was home with her most days. She started proving herself trustworthy and we started leaving her crate open at night. She would usually sleep in it anyways but we gave her the option. We were so lucky to never have any furniture chewing horror stories and she continued to prove herself to the point that the crate was finally put away. It has been put away for about 6 months now, she is left in the house free to roam anytime we leave with no worries. Well last month I started working again, although I am only gone for about 6-7 hours a day. Our girl has completely regressed when it comes to chewing! In one month, she has chewed our couches, an ottoman, her bed, a corner of my carpet, her toy storage bin, etc. I am afraid every day when I come home to see what she has done. The thing is she KNOWS she is in trouble because my happy girl that usually greets me at the door will be hiding under the kitchen table before I even see what she has done, because she knows she did something bad. Same thing when my husband gets home. She runs and hides because she knows she is going to get in trouble. It is just so weird because when I wasn't working, some days I would still leave the house for hours and on weekends if we went somewhere for sometimes 10 hours she would be fine in the house, not a single thing chewed. But the change of me going back to work just has her chewing everything! My first thought is to start crating her again, but I feel bad because she has always been such a good girl and never had this chewing problem before. Any thoughts, suggestions or ideas are greatly appreciated!
