I am sorry that she has cancer. I have had to experience that yet but I am sure I will one day with 6 horses. I have a 13 year old mare that I am not sure how long she will be with us. She has a dropped hip and it sometimes bothers her to walk a lot. I cherish her a lot. Her name is Prancing Timid aka PT. She will be greatly missed when her time comes. For right now I spend my time with her like she has several more years to go.
