Jogging for old dogs

This is Dusja, my oldest dog. She will be 15 years old in June. That's her pose for morning turn

I'm worry about her, she doesn't eat for a week, but I believe, that she is very strong baby I see, that all her body hurts, the eyes don't see good, ears not working... Godness, be with her She is great dog in every time in her life!
