My 15 month old Berner, Hallie can be such a brat when I leave her home alone. I'm in school for 4-5 hours a day depending on the day of the week. She gets a 30 minute walk in the morning before I leave as well as lots of playtime in the backyard while I get ready in the mornings. She also gets 2-3 hour walks in the evenings and goes to the dog park and doggy daycare regularly. I "Hallie proof" the house before I go, trying to put away anything I think she'll chew or get into trouble with. I close the bedroom doors and I give her a denta stick before I go. She is constantly getting into things while she's home alone... today she ate 3 household plants including a cactus, she's eaten 3 pairs of expensive ski goggles, TV remotes, DVD cases, framed pictures, cat food, shoes, leashes, tupperware.... ect. basically anything she can get her mouth on. When I come home to find the mess, She'll be hiding under the coffee table or in a corner trying to avoid me because she knows that what she's done is wrong. I just don't know what to do anymore, I feel guilty crating her during the day and she had several toy baskets with every type of dog toy imaginable that she could be chewing on rather than my house. Any suggestions?
