If you wait, your puppy's «internal timer,» the so -
called socialization window, begins to close (around 12 - 16 weeks of age).
To wit, I have contacted local breeders over the years as a professional trainer offering, as a volunteer, to assist them in assuring the long term behavioral health of their puppies by helping to socialize them and train them in necessary basic skills (loose leash walking, come when
called, focus and attention, e.g.) during that sensitive
window in the
socialization period and before the dogs are sold and adopted.
