I took Aled along to the Midland Cavalier Club mini scanning day at Chestergates on Tuesday, and yes, he's got SM. Mild so far, with moderately dilated ventricles and a smallish syrinx. The plus side is that he has no recognisable symptoms (which doesn't mean he doesn't have any at all, just that there's nothing to pick up at the moment!), and to all intents and purposes he is simply a healthy, happy dog who only sets foot in the vet's for his boosters. After 5 years of living with Oliver's SM, I automatically keep an eye on both of them anyway, and that's all I'll continue to do. Aled was always a risk as he is a puppy farm rescue of unknown background, so developing SM wasn't a great surprise, though it would have been a lovely bonus if he hadn't.
The husband of a well-known breeder recently wrote in a letter to Our Dogs that 'full blown SM with clinical symptoms is very rare' - Aled so far has no obvious discomfort, but he does have CM, herniation, dilated ventricles and a syrinx, which I reckon could be regarded as 'full blown SM', so perhaps I should invite this gentleman to visit my 100% CM/SM household?!
Oliver had a BAER hearing test while we were at Chestergates, and below 90 decibels (ie, me yelling at him to stop trying to get the chicken bones out of the kitchen bin!) he is virtually completely deaf. So a good day was had by all!
