Elizabeth, what the others say is true. We lost our Schnauzer Kona last October, she was 14 and had arthritis, had cataracts, had lost control of her bladder and bowels. We also gave her Rimadyl to ease the pain. For a year she did well, even doing a little running with the other dogs. After that year it all went down hill. Since we got her as a puppy and she was my constant conpanion and I loved her so much, we would decide one day to take her, then we thought no not yet, we just couldn't bring ourselves to let her go. This went on for a while and one day we knew she was in pain and we were being selfish, we were thinking of ourselves instead of Kona and what was best for her. It was the most difficult decision I have ever made in my life, she just closed her eyes and went to sleep peacefully. One day looking into her eyes you will know.
