Some dogs tend to chew furniture.
So why not have furniture that is made from dog food.
You could compress kibble into Kibble lumber for the structure.
The cushions are more challenging.
Here I see some kind of tough non food item rubbery bladders that are filled with soft or juicy dog foods.
Like gravy train or mushy canned dog food.
When beast chews through the cushion he is rewarded with a flood of yummy treats.
You could order and have one sofa per month delivered to your home and never have to worry about feeding your dog.
