Well, by the time you do pre breed testing on all of them (which should be done), save money for emergency c-sections, buy breeding supplies, pay for vet visits, shots, pre whelping care (xrays) and pay someone else to stay with your female who is about to go into labor or your new puppies who can't be left alone, there might be enough money left over for food and toys.
Please research all you can before taking this step.
Most Yorkies on YT probably don't have dog houses at all.
Mine doesn't go outside unsupervised and I feed her homecooked food. Most Yorkies like to be around people.
