When Dazzle was neutered, he came home with an ecollar. He learned to get it off in just 20 seconds! Dad and I took turns sitting up with him that first night home.

If the collar is not too big for her, try putting in on the other way; so it fits like a shawl over her shoulders. It won't bend, so she still can't reach "back there," and it is just a wee bit harder to take it off herself. Plus then she can reach down and eat, drink and such.

Good luck!
