We live in Tokyo, Japan and I have never heard of SM and MVD until my friend told me about it. She suggested that my husband and I should immediately check the site and learn about it. We are actually very surprised and worried about our 2 year old Cavalier dog. Then I went on checking Japanese Cavalier sites, but none of them mention about SM and MVD and I am pretty sure that they are not recognized here. I would like to go to a specialist or a vet who is famillar with the symptoms and take an MRI. Do anyone know a vet/ a specialist in Tokyo, or in Japan? I appreciate if you could help us.
