I'm really at a loss. I have a 13 year old pony mare who has had a chronic diarrhea since I got her about two years ago. It comes and goes and turns projectile for about a week and then gets better. It always comes back. The vet has given her Dia-gel in the past and she's been dewormed. When she gets like this she drops weight, gets lethargic and has no stamina. Then boom she's back to normal. I don't know what to do about it and even my vet is kind of lost. I'm open to any suggestions or experiences that may help her :(
I also have had a surge of mild colic-like symptoms through the barn. I highly doubt that it is sand colic since three different horses have had it and none of them have much sand content in their manure. It starts them laying down, getting lethargic and not wanting to eat anything but grass. Then they spike a fever. I give them banamine and cold hose them to bring down the fever and then they are fine. I'm not sure what is going on and the vet keeps telling me its just colic. They aren't thrashing, biting at their sides, still have gut sounds and pass manure and urine. Two of them have had a tenderness right by the flank, but underneath.
If you have heard of anything, please help :( I'm getting really desperate.
I live in South Florida, if it helps.
