My parents moved to LA three years ago and took their three dogs and cat with them. Whenever I go visit, I am hugged by their pit bull, Champ, even though he was only 4 months old when they moved. He still remembers me and my kids and is sooo happy to see us. The other two remember us, too, even their cat, who is usaully very aloof, will come up to me to be petted since I was the one that found him as a baby and rescued him and gave him to my parents. Your dogs will deffinately remember you.
