Need advice for my mare
I'm new to this forum but I'm kinda at a loss and in need of help. I have a 15yr. old mare who has been having diarrhea on and off for months and rapid weight loss. The owner of the ranch where she is kept has been trying to help me figure this out. She is wormed regularly, fed alfalfa 2x daily, obviously has clean water and bran with psyllium 2x weekly. Now I've put her on a regiment of senior, rice bran as well a kaopect for her diarrhea. I've stopped working her as she is thin and don't want to cause discomfort to her..I love my girl but just feeling really discouraged as to what to do next besides blood work. Vet has been out numerous times and that's when we found LIGHT sand in stool but I've had that cleared up for awhile...any suggestions are welcome!
Thanks in advance
