We have two Yorkie boys. Dudley is 4 1/2 yrs old and 5lbs. Dinkey is 1 yr 3 months and 7lbs. Dudley is the Alfa, but Dinkey is bigger.......so he always trys to take things from Dudley unless Dudley really gets made and snarls, growls, snaps and puts Dinkey in his place. We let him do it because Dinkey needs to know that Dudley rules. It doesn't ever get so bad that we have to jump in. I always buy two of everything to help with the disputes.....
