....any suggestions on ways to deter it? The foster dog we have staying with us now has 7 stitches above his back leg, poor little guy, and he's obsessed with them.

He seems to have become immune to the antibacterial/deterrant spray we have tried. I have an e-collar for him that he's getting used to, but my other dog keeps chewing the rim of it so it's sharp and dangerous I'm keeping them apart as much as I can but can't leave the foster inside when I go out.

Just hoping someone might have another suggestion that's worked for them? Or do I just have to ride it out.....
