More: Best dogs I’ve ever know. Lily suffers from IVDD and was paralyzed last year. We crate rested her, basically did everything for her. During her convalescence her sister, my sweet Lucy, passed away in her sleep due to a heart problem. Lily now walks again and has a sweet life but misses her sister. Lucy we got as a puppy, but we are Lily’s 3 and forever home. She had been terribly abused in her second home. Lucy & Lily were litter mates.
