Bella 16 came down with cold symptoms last week lots of sneezing not eating all her food. Made a vets appointment for after the weekend as advised so that's later today. Her sneezing is improved but she seems to have aged really quickly, she's tired, not interested in dog food so I've been cooking meat and veg over the weekend for her to get her to eat, she looks frail and every one day of those sixteen years and I think we might lose her. I know she is 16 and a good age but I'm not ready yet although I won't see her suffer. Any words of wisdom?
