No - you cannot make money breeding Yorkies. Oh not saying you cannot buy an inexpensive pet Yorkie, breed it once (and not have any problems such as C-section) and sell all the pups and make some money. But to say it is a way to supplement your income - wrong! I have been breeding Yorkies for 30 years this March and in those years, I have made money one year, broken even 2 years and lost money all the rest. Although Yorkies are my passion, I do not do it to make money, but to have fun! I love the breed and love to watch puppies develop.
Best of luck to you.
