Not meaning to sound horrible, maybe putting your dog down now would be more humane and less painful for your pet then dragging it out. I'm sorry to hear about your pet...
I would never let Toby suffer. He means the world to me and I would rather suffern than him. The vet doesn't believe he is in pain based on his slow, regular heart beat. He said you can't always judge by their actions because it is their instinct to hide weakness but animals in pain have an elevated heart rate. We keep him on a low dose of pain medications to make sure. He still has that light in his eyes that says he is enjoying life. The first sign that he is not will be my sign that it is time.
Thank you, sincerely, for your concern. I would rather put him down a week too soon than a day too late to avoid him being in pain.
