You need to check parents have been health tested for breed related faults and genetic conditions , also make sure that if pup is KC registered that you get papers when collecting pup do not fall for the " I will send them on to you "scam as you might never get them
If you need any help I am willing to help you out , by the way pugs are great wee dogs
Good luck
