Actually, my breeder gave us Jackson at 8 weeks because she believes this is the period of bonding. We had NO problems with Jackson whereas the other 2 Yorkies that we had to return came to us at 12 weeks each and one was sickly and the other vicious!They were all form differenty breeders. A good breeder will:
give you names of people who can recommend them
have the mom or mom and dad present in the house
check YOU out
let you see the dog before you pick it up
refund your money if for any reason you do not want the puppy
answer your questions and concerns AFTER she has your money!
