There are many breeders who do a great job of raising a puppy from birth to 8 weeks but so much more care and attention goes into raising them right past 8 weeks. If they are not properly socialized they become scared, skittish, may have fear aggression, become a barker, develop anxiety.
We have developed a program to take them past the 8 week mark and keep them socialized along with helping them develop life skills without picking up negative baggage
