She wants to get out of work or she’s “playing” just don’t let her and when she does back her up😊
Thank you Silje! I feel reassured :-)
Hi Lucy, thank you! I have been riding her in a hackamore since she started yawning and have it really loose so it won't be because it's too tight but I can see it logical that she is getting oxygen to her muscles ready to work! Thank you I feel less worried now :-)
Similar to us, horses yawn in order to gather enough oxygen to provide for their working muscles - especially if they know they are going to begin work. Mine would do the same sometimes if she saw me bring the saddle towards her, but has stopped doing so recently.
Since you said that she only seems to yawn when you have her bridle on, this could actually be a sign that the bridle is affecting her ability to breathe properly. Perhaps the noseband is too tight, or the pressure from it is affecting her ability to breathe as she would do normally, therefore it is instinctual for her to want to yawn in order to provide her muscles with more oxygen.
I'd advise that you check the tightness of the noseband and, if it is too tight, to loosen it.
Yawning isn't a problem - but if done often by a horse it can become a bit of a habit, which could be why she continues to yawn, though I wouldn't worry :)
Hope this helps!
Mine does that too, when he does it I know he’s getting ready to work. maybe that’s why you’re horse all so do it
