Since we came home, she was destructive every day, she tried to dig through the walls, ripped her claws off, escaped out of the window and ran off etc. We went to the vets several times with her, and they gave us techniques to try with her (kong, super long walks, crate) and nothing worked, spoke to the rspca, where we adopted her from and they weren't any use either. She was unhappy too, not eating, not playing, just moping.
Eventually we found that shutting her upstairs with a stair gate, bed, food, toys and water worked and she became happy again, and settled down, until today. We went out for a few hours and came to back to find piles of broken crockery, torn down wallpaper, broken plaster, paperwork shredded. We have no idea how she got downstairs, the stair gate was still up, so guessing she jumped it.
Has anyone got any suggestions of how we can help her? Crates really don't work. She's terrified of clangy things. We can't afford to keep re plastering and re wallpapering and replacing things. The first few times, yes, but we've had her 18 months, shouldn't she have settled down with us? Any ideas are gratefully received, I love the dog so much, but we are close to rehoming.
