Too many bad news at once. I sincerely hope you'll overcome this very soon. I've been away from the site for a while, but still remain in contact with a few great TN people. Kind of people you know they exist somewhere in the world and that they share many things with you. I'm sure you'll be encouraged by many of your friends and that this will help you a lot.
I just noted this in your message
"I think dogs are Gods gift to man." .....DEVOTED..NEED I GO ON?"
No, I know what you mean. The best therapy you can imagine!
So, if the worse happens to her, and if I may talk by experience, never leave your home without a dog for the future.
