Hi!
Boo was 5 yrs old when 3 month old Gracie Ruth joined the family. I was thrilled at how good he adjusted to the little monster in the house.
We just made sure to give him some one-on-one special time and to be sure that G didn't bully him. He wasn't allowed to be ugly to her, but he could say no to her demands to play without getting in trouble. Puppies have endless engery and they can get a little pushy sometimes.
