Alison, I think we all must check the "Dog Health" section daily to see if there has been any new posts from you. If there is ever a site that honors the Guardians of Dogs, you have to be the first honoree. Having dealt with two aging dogs in the past, I know how devastating the illnesses and infirmities are, but this is beyond comprehension. May God give you strengh to cope and guidance in knowing what is best for Bella.
