I am assuming you mean emotional support?
Purchasing a well bred dog is cheaper in the long run. Fewer health issues.
I had one Yorkie was was beautiful but not as well bred - this was before being as well educated - when the health hit at about age 5 it was very, very costly.
My current Yorkie was a top,of the line breeder pup and is the healthiest dog I have ever had. So I'm prone to thing you pay at one end or the other.
I'm also a fane of health contracts, DNA, and bile acid testing.
Good luck in your search. I can hear that you are a Yorkie lover.
You could look for a YTCA breeder in your area. Often they has pet quality pups they like to find good placement for.
