Steph Curry's got a brand new family member -- he's adorable, he's furry and he ain't cheap!
TMZ Sports has learned Steph and Ayesha just brought home a 10-week-old Goldendoodle puppy this week from a place called Murphy's Doodles ... a high-end breeder in Florida.
We're told the NBA superstar and his family fell in love with the pup from the moment they saw him -- specifically because of his green eyes (like Ayesha!) and dropped $3,800 to add him to the fam.
The kids got to name the pup and went with "Rookie" -- and it appears he's already getting along with the family's other dog, Reza.
Congrats, Rookie ... you're about to have the greatest life ever.
