Dr. Singleton and his staff are amazing. My 6 year old mixed breed Westie went into congestive heart failure unexpectedly. I was at the door when they opened & they took her right in, put her on oxygen, lasix, x-rayed her and monitored her closely till she was out of the woods. She will be on heart meds from now on, but without him I wouldn't have my little girl. She is doing GREAT thanks to Dr. Singleton.
