Linda said:I got Darby when Dudley was just almost 2 1/2 years old.
I would definetely wait a little longer, as you will be making more work for yourself too.
They will bond with one another regardless of the age, I thought my two were never going to get along. Dudley was so mad in the begining and would not look at us or talk to us for sometime. He is now well over that and is much more active with Darby around he has no choice.
Aaaaaaaaaaaaaah he also eats now, my headaches of the finicky dog are longgone.
He still likes his quiet time though.
