We have had MILs old mare for about 5 years and she is a very hardy welsh mountain pony who has always lived out without a rug.
This winter she has started to look really old and has lost muscle tone. She is 28, still lives out, has a huge winter coat and a good apetite (has a bucket of food every morning and night plus hay).
Should I be doing more for her? I do feel a bit sorry for her as she really does look old now? Is the muscle tone loss normal?
