Sorry she is starting to have trouble. The black and white ones are beautiful dogs, and Belle looks a great deal like Rags, the 2nd one we had. Sadly, ol Ragsie had the same conditions as Belle. She made it for several years before we finally had to let her go. She started having seizures, which are horrible to watch, and very scary for the animal when they come out of them because it supposedly affects their vision pretty badly. Having to make the decision to let them go never gets easier. I've had to do it for 4 Shi Tzu's and a big orange Tabby cat. All were hard, but Prissy affected me the worst. She was with me for 1/4 of my life. I wish the best for Miss Belle.
