Hi. I got a yorkiepoo a couple of months ago and I didn't know alot about his breeder

.(sorry..i should have been better educated). My puppy is now 4 months old and he's 5 lbs. I do not know if I purchased a standard poodle and yorkie (which i what I'm guessing) or a what?? I'd also like to know how big he will get. I can't seem to find an "guestimate" on this anywhere. My guess is that he won't get any bigger than 10 lbs? Am I just being hopeful? (he's got WAYYY more yorkie than poodle.)
