A second opinion is a good idea, yet you might just get the same from the second opinion vet. We have tried a couple of times talking to vets about SM/CM. The first vet we talked to just shrugged it off and said it wasn't worth giving such a young dog an MRI and the experience he has had with cavalier owners getting scans is that they all turn out negative Our girl Belle has exhibited the rear end turning (rarely) and chin rubbing (getting more frequent), but seems to be a happy healthy dog otherwise. A few months ago we went to a recommended vet and he said she probably has SM as all cavaliers have it and just keep an eye on her and if symptoms appear more or get worse then we'll opt for medication. So it's a tough one. Sometimes I worry so much about our dogs health and bring them into the vet, I'm afraid they think I'm one of those neurotic moms who thinks their kids are always sick. I don't know- it's like waiting for a time bomb.
Our Bobby seems fit as a fiddle, yet he has the wonky knee, which is at a grade 1 right now. It's all very sad. I don't know if I would ever get a purebred puppy again, cavalier or any other, there is just too much heartache and worry involved. That is the way I feel at the moment anyway. I want the cavalier breed to survive, and would like to contribute to helping the cause any way I can, even if it's donating a few bob to Rupert's Fund.
