I don't worry about Jake at all. At almost 9 years old he is completely symptom free. I am much more aware of Micah at 17 months and was very aware of his behaviors his 1st year. I do find myself picking up on the behaviors on other people's Cavaliers. In fact, saw one a couple of weeks ago that I was sure was symptomatic for SM. Told the owner about SM (she didn't know anything about it) and she has since seen a neurologist and spoken with the breeder and is now discussing an MRI.
Those who have had a cavalier with SM, do you find yourself more aware with your second cavalier or others?
