I have a 14-year-old dog who has a spinal problem that causes great pain at times. My vet in CM, who is the owner of the practice, told me without asking that she would euthanize him when I'm ready. In the meantime (now about every two weeks), he gets a shot of morphine plus an anti-inflammatory, plus a 3-day Fentanyl patch, and he's happy for about two weeks. He has been attending this practice for about 18 months.
