My bulldog (Lily) is almost 6 years old and we're about to add a new puppy to the family. Lily has always been really good about not eating other dogs food (when we have overnight guests) because she knows it's not hers. Feeding them the same brand will definitely make my shopping easier, but I'm wondering if it might create jealousy between the Lily and the new puppy. Any theories/experience with this would be appreciate!
