[{aspiring_to_clarity}]

BeyondBewildered, I didn't mean to imply that you were incorrect in your assertion, just that I had not heard the information before. I did not go back and re-read your original post so did not remember that you said that it prevents ovulation and fertilization was correct, but that there was a possibility that fertilization could occur in which case it would prevent implantation. I have no problem believing what you say is true on the word of the doctor's you have spoken to. It makes sense. It would be nice if there was a method which completely prevented ovulation/fertilization 100% of the time (other than barrier methods - which aren't 100% anyway).

I am sorry to hear about your dog. I recently went through a similar experience with two puppies I had. It was very tough. I also lost my grandmother a couple of months ago. She went downhill pretty fast and knew she was dying. One day she wanted the doctor to give her something to end it. The next she said she was glad to still be here as long as she could drink her cool water and feel the breeze. She died about 3 days later. I know she had a tough time, but I also know I could not kill my grandmother. I sat by her bedside while her breathing became slow and labored. I was holding her hand when she took her last breath. I thought maybe I would die. So for me the question of euthenasia became very real and I probably have more conflicted thoughts on it now than before.
