It hurts my heart to hear this. Little Nadi always puts a smile on my face. To know she is sick now I am sure really upsets you. When I lost my Bailey girl a while back it threw me for a loop. I still miss her. Let's hope the vets can help her out and give her some more time for you to enjoy those walks together. Or at least some time hanging around just watching people.
