Actually its "dont look a gift horse in the mouth". It means dont judge a present somone gave you. This came from when people gave horses as gifts. The gift horse was usually old, and you can tell a horses age by looking at its teeth.
By looking a horse in the mouth, you can tell their age and whether or not they're in good health. But if you get a horse as a gift, you should be happy to have a horse and not question what shape they're in.
This is a horse term. Flogging is beating with a whip. It does no good to beat a horse that is dead, because it will never get back up and work for you.
Think about that for a minute and you can figure it out. What good would it do to lock up the barn after the horse ran off?
It's not an idiom, it's a saying. If the horse is blind, it can't see either the nod or the wink, so they'd mean the same thing to the horse. You nod when you're agreeing and you wink when you're sneaking around with something.
This idiom comes from horse racing. You'd bet on whichever horse's nose would come in first. If you make a good guess, you're "on the nose."
A good bit is a snaffle or happy mouth
"I got it straight from the horse's mouth." "Don't look a gift horse in the mouth" "I'm so hungry I could eat a horse" "Stop horsing around" "Get down off your high horse" "You don't shut the barn door after the horse gets out" "You can lead a horse to water but you can't make him drink" (this one is actually true).
A horse's teeth are a good measure of its health. So if someone gives you a horse free, you don't immediately start inspecting and reporting on it.
No - you can estimate a horse's age by looking at its teeth. Looking a "gift horse in the mouth" would be like judging the gift's value or appearing ungrateful. The general idea is: it may not be ideal (like an old horse) but it was free & you can still make good use of it & be grateful for having one at all.
A good idiom would be "sitting on the fence."
The meaning of the idiom in the pink of health means being in good health.
if your horse has collic, take it to the vet imedatly... my horse died of collic. Good luck :)
