I so know how you feel, but hindsight is always perfect.She had love and caring till the end. And that matters more then anything else. And i am sure she felt that love. Now she can run free with all our Angels at Rainbow Bridge.She passed a couple of hours ago...her breathing was so lab ored, she became very cyanotic, would/could not move. my daughter and her ex boyfriend and my best friend came and helped me move her to the ex's car and the vet met us at the office and put her to sleep in the car. She was so ready, she was exhausted. I will miss her so much. I should have done it this afternoon, she was really suffering this evening and I feel so bad that I had not anticipated this rapid deterioration. She was so wonderful, smart and loving and everything a newf should be.
