I have located a 6 week old Chi puppy and we will be driving 12 hours to pick her up from the breeder. I can go get her at almost 9 weeks of age or at almost 11 weeks of age (the weekend of her 10th week we cannot leave town). She is good-sized Chi -- charting to be 5.5 lbs. Some sites say 8 or 9 weeks is the best age to bring a puppy home and any later and the puppy may not bond with the new owner. But others say 10 weeks or older.
