I've followed this thread from the beginning and have posted to you my thoughts on the situation. I do think it is definitely time to do the right thing and put her out of her misery.

As I posted before, I too have had to go thru this but my first priority was to make sure that my dog had a decent quality of life without pain - if I couldn't be assured that it was the case then I knew it was time to do the right thing and have her put down.

Yes it is hard and very painful but you are her owner/best friend - you have to be strong and do what is needed. Please don't put this off if you truly believe she is in the sort of pain you have described - "you" must take care of her by helping her to pass into doggie heaven.

Please don't continue to put this off - I fear from your description that your dog is simply suffering because you can't bear the thought of losing her. Be strong and do the right thing.

My prayers go out to you and your pooch.
