It's kind of interesting to learn about this whole canine teeth thing. They are the teeth most likely to be hit by a bit when the horse is bridled. Mares with one canine are middle of the road and mares with two or more canines tend to be the moody mares, sometimes hard to get into foal, sometimes act studdish/hormone imbalance and top of the pecking order. It is mostly male horses that get canine teeth, but you can see them in the occasional mare also (25-30%), but then usually very small or as a bump on the bar unerrupted. Canine and wolf teeth are two completely different kinds of teeth. 472 Posts. var _nwls=[];if(window.jQuery&&window.jQuery.find){_nwls=jQuery.find(".fw_link_newWindow");}else{if(document.getElementsByClassName){_nwls=document.getElementsByClassName("fw_link_newWindow");}else{if(document.querySelectorAll){_nwls=document.querySelectorAll(".fw_link_newWindow");}else{document.write('<\/scr'+'ipt>');if(window.Sizzle){_nwls=Sizzle(".fw_link_newWindow");}}}}var numlinks=_nwls.length;for(var i=0;i
