My tri-color male, Oz, (now 11 months old) was diagnosed with a grade 1 heart murmer and intermittent 2nd degree heart block at 4 months of age. He had a stumbling episode in which he was oriented (so not a seizure), but kept falling down. He has since been diagnosed with a very mild case of syringomyelia (a 1 on a scale of 1-10, with one being the mildest). He is not on any meds for either condition. He did wear a holter monitor for 24 hours for his heart - based on those results the cardiologist just said to monitor his murmer and more testing if it gets louder or he becomes symptomatic. Does anyone have any experience with cavaliers who present with a murmer at such a youg age? He is really active and just a fun puppy. He was checked for SM because I just became aware of the condition when one of my older cavaliers (I have 4 total) had decompression surgery last week and Oz was scratching a bit more than the others and because of his stumbling episode. Any words of wisdom from anyone? Thanks.
