I'm sorry to hear about your pet's medical problem, it is really hard to hear bad news about both people and pets that you love. I really admire dogs, they don't care if your messy or overweight or if you wear glasses or if you have mental illness...and they don't get upset if they have a medical problem and it causes them to lose a limb. Maybe we could all take a lesson from those compassionate, happy dogs. In any case i hope you start to feel better.
