I don't think there is any way of stopping the inappropriate chewing other than putting everything away and out of reach, thank goodness she leaves your furniture alone
Chew toys are good but not as good as forbidden stuff, to a Basenji.
Some are worse chewers than others, my first Basenji specialised in chewing pens and combs, the worst things he got were my Husbands new glasses and MIL false teeth.
Malaika goes more for material things like rugs and towels, hence the bathroom door is kept closed and the holey rug is left down as there is no point replacing it just yet.
Forbidden stuff is really awesome! Simon will fly through here with a nice new roll of toilet paper, laughing, bowing, prancing. He's fast and I'm slow. I oblige him by waving my arms around and hollering. Sometimes we can salvage some of it once we get it back.
So the other day husband John offered him a partial roll. Simon looked at it, looked at John, walked away. Apparently toilet paper rolls are only fun when someone is chasing you
Simon is a shredder, and he DOES like the furniture. We're hoping with age comes wisdom, but for now we use gates.
The thing I worry about is fibers wrapping around his intestines. I don't care about the bedding getting ripped. I just don't want him ingesting it. And so far he does leave the "harder" stuff alone. He doesn't care so much about remote controls and cell phones. He wants the undies and the kitchen towels. He's a bit girly maybe
Obviously, the only advice I have is to use gates. If anyone comes up with a towel that is immune to basenji, please let me know immediately!
