More reasons to never pull the rein and have a stable contact.
A horseās mouth is very sensitive, as it is densely populated with mechanoreceptors allowing it to sense temperature and touch. The soft tissue in the mouth - gums, inside of the cheeks, and tongue also has a high number of nociceptors, specific receptors that detect harmful or potentially harmful stimuli that can cause tissue damage. These signals are carried to the brain where they are converted into conscious experiences of pain.
Wounds on the tongue, bars, corners of the mouth, bruises, inflammation, and impeded blood flow (blue colour of tongue or mucous membrane) will cause PAIN!
Bit-related injuries are common, but because they are not always visible, as they are in the oral cavity, they are often ignored. Many studies are reporting bit-related soft tissue injuries in the mouth after a race, after a cross-country test or in dressage-, polo- or driving horses.
A study of K. Tuomala (1), reported the occurrence of oral lesions in a bit area in Finish trotters after a race. Of all the horses examined, 84% (219/261) had acute lesions in the bit area. In total, 21% (55/261) had mild lesions, 43% (113/261) had moderate lesions, and 20% (51/261) had severe lesions. This statistic is pretty scary. This isnāt OK.
Even more scary is, in my opinion, that horses are clearly showing their discomfort or pain in the mouth. Fighting the bit, keeping their mouth open, crossing the jaw, chewing, holding the bit between their teeth, tongue persistently moving or protruding from the mouth, tongue placed above the bit, head tossing, stiff neck, behind the verticalā¦..wellā¦those are examples of behaviour that was noticed in ridden bitted horses (2). When there was a change made and horses were bitt-free, most of these behaviours were absent. Why is this a surprise?!
Horses suffer silently, but they DO communicate with their clear, silent language ā with changes in their behaviour, facial expression, posture or movement. Why Is it so hard for us to learn that?
LETāS DO BETTER!
Love the cooperation with Dr Heidi Nielsen, Caroline Davies and Dr Popkova. Thank you ladies for raising the awareness.
