Bloodmarks are rare markings that occur in some fleabitten gray horses. A fleabitten gray is a rare recessive form of gray that causes flecks of the horse's base color to appear in the horse's coat as it ages. All grays get lighter as they age, but fleabittens begin to get flecks of color that return to the body. When these 'fleabites' appear in one area, they may create a patch known as a Bloodmark.

Bay and chestnut based grays will have red markings, hence the name 'blood mark'. Black based horses will have black bloodmarks.

It would be assumed that palomino and buckskin based fleabitten horses would have yellow colored markings, but as these are extremely rare I have not been able to find any photos or instances of bloodmarks on these horses. If you have any information, please email me.

"The roan patch on her shoulder has faded now that she is in her 30s but the spots on her neck and jaw are as bright as ever. These spots are solid with no white hairs in them"

Edward Lord Harley, said of the horse by the age of six the marking was "now much wore out, but when I bought him was as red as blood." Generally bloodmarks should increase with age.
