My 10 year old Arab mare has swollen glands from under her ears right down to her throatlatch. She is not displaying any weird behaviour, is eating, drinking and defacating. She does not have any nasal or eye discharge. She is absolutely normal despite the swellings.
I have asked around and some have mentioned "grass glands"...we have had a lot of rain here, there is new growth grass which is high in sugar this time of year. Perhaps a starch/sugar overload.
Does anyone have experience with this or can suggest anything else?
She has been swollen for a few days, if it persists much more I will consult a vet.
