Thank you so very much for your concern and suggestions regarding
dear Chloe and Daphne's fence chewing.
I must allay your fears...they are definitely not cribbing.
Chewing is sometimes confused with cribbing, however they are two different things.
When a horse cribs, they lock their teeth onto a fence or stall wall and draw air
into the back of their pharynx.
Rarely do they eat the wood, but rather use it as a means to hold fast
while they arch their necks and suck air.
They have found through fluoroscopic studies,
that the equine does not actually fill their belly with air, as was once thought...
but rather just fills the back of their pharynx and then exhales it again.
Apparently this causes an endorphin release.
So, in essence, it is a bad habit that is actually a way that horses self-soothe...
and one that is very hard to stop...as there is so much positive reinforcement from the endorphins.
What these girls are doing...
is just plain old eating my fence.
Donkeys eat wood to get more fiber into their diets.
It's important to remember that donkeys come from arid parts of the world with poor vegetation...
so, tough, woody growth is natural to them.
So, while I don't appreciate having to...
