It sounds like you made the right choice. my dh and i had our Baby for 18 years. She had been with us since we met. It was a hard choice. The hardest! But I could not put her through all they wanted to do just so she would be around for a month or so. I felt we would only be doing it for us. When she went to sleep I swear she looked young again, she looked so peaceful and beutiful. Oh she was in stages of kidney failure. I don't regret it it was the best thing. We now have Aki who really needed a home I am glad ours was open for her. It was about a year later when we got Aki the timing was right. A big hug goes out to you in your time of saddness. But please don't forget to celebrate the time you did have, which sounded like a good long time.
