Dogs recognize the scent of their mothers for up to a decade.
One study found that puppies could recognize the scent of their mother after a 2-year continuous separation.
According to the Handbook of Applied Dog Behavior and Training by Steven R. Lindsay, dogs are capable of recognizing their mother and siblings later in life if they are exposed to them during the crucial period between 2 and 16 weeks, and especially at 8 weeks.
A 1994 study “demonstrated that offspring recognize the scent of their mother … after 2 years of continuous separation.”
Other researchers later showed “that dogs recognize the scent of their mothers after 6 years, and, possibly, as long as 10 years after separation.”
They found that dogs could recognize the hand scent of the breeder for 4 years and possibly as long as 9 years after separation with no contact in between.
I’m not sure if Lulu ever thinks about her mother, but I would like to think that her mom is happily living with a nice family somewhere, quietly enjoying what must be her golden years now.
Do dogs and cats think about the parents and siblings they were separated from in early life.
Do their mothers wonder what happened to them.
And would they recognize them if they met later in life.
