My three dogs have a neverending need tp chew. I but them rawhode bones but they go through them in a day and they are expensive.
What can I buy/get that is cheaper and might last longer?
Raw bones. Big ones.
What Sandman said.
You can also get the rawhide chews from Costco - about NT$350 for a bag of 25 or so - much cheaper than buying them individually.
Or give them furniture - that’s what I did.

That’s why I asked the question. My dogs are eating my coffee table. :s
Try giving them some cats. I hear that dogs like to chew on cats. Or maybe a mailman. The mailmen here ride motorcycles. Give them that as well. I bet it would take your dog a long time to chew through a mailman on a motorcycle.
Otherwise you could find some pure capsicum and brush it onto your furniture. I think it might melt most wood finishes. Not sure. Give them something that they are allowed to chew, and train them to not chew other things.
