I'm sorry you're having so much trouble with Ivy chewing. Some pups are worse than others. I had a Shepherd/Collie once that chewed until she was two years old! Yep, ate pieces out of the wooden basement steps and even ripped up the linolium in the kitchen. It's pretty much hide everything and/or confine the pup any second you can't be watching her. I hope you have better luck with Ivy in the future.
