This weekend I noticed Shiloh starting to "groom" Fenway. He will just lick and lick and lick him, his face....his fur...his privates....it reminded me of watching monkeys pick bugs off each other. Is this normal when you have more than one dog? We have had Fenway for about a month now...and they seem closer to each other, sleeping curled up with each other and now this "grooming" thing. I am glad they like each other, I am just curious if it is this way for others.
