Hi! I am basically here and looking all over the place for others who have Cavaliers and may have a Cav with the health symptoms mine is having. He is just turning 1 and has some very significant lameness and terrible tremors which occur when he gets excited. Two vets have both ruled out brain tumors and syringomyelia. He has been blood tested for myasthenia gravis and that turned up negative also, but the doc says that test can produce false negatives. I'm hoping to find some insight to what is going on with him. He is a very good little boy and my best pal. You can check him out on my website http://jencrowder.com/portfolio.html Click on pets and he is the little cute tricolor cav!
