We have two cavaliers, Sam is 4 and Louie is 2, Louie is our newest edition and has been with us nearly a year. Sam is neutured and Louie is not but they have both started wetting inside the house. This is happening on a regular basis. Our vet has recommened we have Louie neutured and they are trying to vie for top dog. Has anybody else had this problem or has anybody any advice. Please help. :? Thank you
