LOL!

I feel your pain. My pup was a chewing nightmare. She's always had loads of chews, filled kongs/filled bones etc. Loads of mental exercise. Loads of (age appropriate) physical exercise. She's not left alone much as I'm in all day, apart from school run/Tesco type outings and yet we have huge holes in our dining room wall (it's now the dog room but you still don't want it to look like a WW2 bunker, do you?). We never thought she'd ever grow out of it. She did, but it did take a while. She's a year old now and never (touch wood) chews anything except her chewies - although we never leave anything around that we don't want chewed, just in case.

Crates help enormously. If we go out now I still leave hollow bones for her, filled with wet food and frozen, which A) Takes them longer and B) Is nice for sore gums when they're teething.

It will pass. It just doesn't feel like it will
