Hi! I am very excited to be a part of this site! I have two senior cavaliers, both were show dogs that were no longer showing. Our Tri, Polka, is 13 1/2 and our Bleniem, Colleen, is 9 1/2. We have had Polka since she was one. We were blessed with Colleen 2 years ago. They both have mumurs. Polka has had hers since she was young, but it hasn't really gotten worse. Colleen, I am very concerned about! She is a grade 4. We are about to do all of the xrays and ultrasounds to see where she stands. She isn't showing any signs of distress, luckily. It is hard having 2 senior dogs. I adore them both!! I think this website is going to be very valuable to helping me through this with Colleen and what is to come with Polka. I will post pictures later. Polka usually runs from the camera. So we shall see how that goes! - Megan
