Hello, This is quite a long story, so thank you to anyone taking the time to read through it. I am having some severe behavioral issues with my 8, almost 9 year old Labrador. About two years ago, when we were living in Melbourne, she started displaying very strange behavior that I'd never seen before. She would sit at the back door and shake and whine, looking very distressed. She would do this even when she couldn't see us inside. A few days later I got home to find she had escaped the yard. I had no idea how she got out until I saw her scaling the back fence, a tremendous feat! I pulled her down and she was pacing the yard whining, with her tail between her legs. She managed to escape two more times. We installed some new fencing that she could just fit her head through, and I once watched her trying to push her whole body through this fence, with her tail tucked so hard underneath her, whining and just so determined to escape the yard. She had huge cuts on her chest from trying to push through. And one day this all stopped. Nothing had changed, I have no idea what brought it on or what stopped it. A year ago we moved to a smaller rural town, and I was convinced that the strange behavior was behind us. Until about a week ago I noticed the signs; digging in the yard, acting desperate to come inside all the time. And last night she dug under our fence and managed to squeeze out and run away. Again, nothing changed in our yard, in our schedules or behavior. I am so worried because when she wants to escape it's like nothing will stop her. She's like a total different dog, it's like she's possessed. She has regular vet checkups and is healthy. She eats fine, loves going for walks. Yesterday she was fine all day; eating her Kongs and laying in the sun. But then out of nowhere she "goes crazy" and escapes. Any help/advice would be so greatly appreciated, I am at wits end and have no idea what I should do. Thankyou so much.
