Johnny's vet calls it "happy pee." At his first visit, I mentioned "excitement urination," wanting to use the right term and Dr. H immediately said, "happy pee." He also said many will outgrow it and that some males stop after being fixed, but it could be a life-long habit. Johnny has outgrown it with several people so I have confidence it will get to be everyone some time. He's just so happy to see people that it happens and this is a dog who is alone no more than 3 hours a day-some days, never alone.
