We're lucky. Kipawa chews his toys and nothing else. Ooops… forgot about the odd soft blanket under our comforter on the bed. It looks a little like swiss cheese - with holes! But that seems to be it.
As for furniture, ours is leather. But it was purchased before we got Kipawa. I picked the most buttery leather I could find. It hasn't held up to scratching, but I am not surprised. To avoid further damage, we keep Kipawa's nails trimmed short using a dremel, to give them a nice rounded edge. If we repurchase, I would go with leather again, but a much tougher hide and a different colour.
Kipawa is pretty well allowed anywhere in the house, just not on tables or of course the kitchen counter. If we let him up there he would think he had died and gone to heaven! Because that is where all the yummy stuff seems to be living.
We have used the Bitter Apple spray with success. Also, if you don't mind the smell and if whatever item in your house can not be ruined with it, a tiny bit (with a Q-Tip) of real Tea Tree Oil really makes a basenji turn up their nose. We use Tea Tree Oil on Kipawa if he has an owie that he over licks. It works great.
