Buying them from a breeder can cost you anywhere between $1,000 to over $5,000. Teacup Yorkies cost less when they are rescued or taken from a shelter. You can rescue a teacup Yorkie at the average cost of $400. This price doesn't yet include everything you need to clean it and give it a good environment to live in.
You should also think of the cost of owning, training, feeding and watering the Yorkie. This means they will get a wellness exam, get their behaviors tested out, and possibly get vaccinated.
