I got Precious at 6wks. I don't have her around dogs very much but she seems well socialized with them. Well, she's a bossy thing and has any dog following her lead!
I didn't know 10 wks would be better though, although it is law out here that puppies must be at least 8wks to sell. OoOops! HAHA oh well, I'm glad I didn't have to wait another second! ;-)
