How do I know if my horse in overweight? If she is how do I put her on a diet. I've had people ask if she's pregnant. She's not pregnant. She's 14.2 hands and last I checked 900 pounds but has gained quite a bit of weight. Shes also on good grass hay, good grass, getting vitamins and is up to date on worming. Please help idk what to do.
Please take it under advisement that I am brand new to the horse world. If anyone gives contrary advice to anything I say, I would disregard mine. That said, I've been in charge of adjusting diet to keep sixty-five horses at their correct weight.
My rule of thumb is this: If I can see the horses ribs as it is simply standing around...it's too thin. If I can run my hand lightly over his side and feel ribs, he's just fine. If I need to apply pressure to his side in order to feel his ribs, he needs to go on a diet.
There are exceptions, for instance one horse is about to begin training for an endurance race so I'm letting him pack on a bit.
It is my opinion that height and weight are irrelevant to a reader of this post without the breed of the horse being taken into consideration. I could be mistaken on this one.
You say grass hay and grass - so if that is correct, and assuming you have her in a place she can graze and simply supplement with hay...then if the grazing grass is sparse, I'd cut down on the hay you feed her. If the grazing is plentiful though, any cut back on the hay won't help - she'll simply graze more. In that case I think I'd have to limit her grazing time.
I hope there was something in there of value for you. Best wishes.
