I am going through great grief. I lost my lovely shih-tzu 'Chanel' last week to leukemia..It was so sudden and I am in deep shock..I had taken her to the vet thinking she might have a touch of arthritis..but finding out this dreadful news and had to have her euthanized right there and then...She had been my companion and like my child for 10 years and I feel as if my heart has been torn in two.I am walking around in a fog and tears-tears-sobbing.
