Cruella has it right. It barbarically exploits animals, it's unnecessary, and so on. Minks live longer on fur farms than they do in the wild. Dalmatians, one imagines, could roam more freely on a large farm than in a cramped urban apartment. And Dalmatian farmers would not simply kill Dalmatians for their fur.
Dog meat is prized in other parts of the world.
Dalmatian farmers can set up shop in places where dog meat is eaten. The second objection to Dalmatian farming is visceral. The mere thought of farming dogs for fur nauseates you. With this objection, I sympathize. Dogs are charming.
