bro serious question: why do people put their dogs in cages inside the house ?

Only time we put our dog in a kennel was when we left the house because he would eat the furniture. Turns out he would eat the kennel too, so we keep him outside. We didn’t have a fenced area for him at the time, we were in the process of building it. Now he hates even being inside, just wants to go out and look for lizards to eat.
