So two of my horses seemed to have a cold or allergies. My mare always struggles this time of year with swollen runny eyes (allergies) so I thought no big deal. My gelding had a slight random cough and runny eyes (I thought allergies), neither had/have nasal discharge. All three horses are eating, drinking, passing normally. My gelding is acting fine now, no more cough and his eyes are cleared up, the other gelding is fine.
BUT, I was feeling around on them and all three have "slightly" enlarged lymphs if I feel for them and my mare is swollen under her jawline.
Going to rect her in a bit and I'm calling the vet in the morning, he's off today. All three are breathing normally, my mare has been in so she is bossy and crabby but still her normal sleepy self when I'm out there so it's hard to determine if she's lethargic.
SO, these three have been together since December. No signs of illness, all UTD on shots done in the fall. All three are acting normally, eating, drinking, playing, romping and galloping around in the evenings. I've been watching them closely! They are 100% isolated, no other horses within 12 miles, haven't been anywhere in two months and only then on a couple isolated trail rides.
COULD one of my horses be a strep carrier and infected them after being together for over 5 months and just now think I have an outbreak?
Vet is being called out asap to check them.
