Okay, so the vet left about half an hour ago and the outcome was good.
He said it's NOT contagious, it's not a cold etc, he said by the looks and sounds of things she has managed to get a foreign body (eg twig or something) up into her sinus, so effectively she has sinusitus(sp?)
Because it is only snotty on one side he said that is the most likely cause. He said it's not bothering her, she has a good appetite, her overall condition is very good and she does not seem bothered by it. The breathing difficulty sound is just a sound, he said seeing as she is semi retired it won't need big time treatment which would cost thousands due to the shape of their sinus cavities being poorly designed.
She has antibiotics for 6 days twice a day, in powder form mixed in damp feed with mollasses or honey (which is good she loves honey). And he said if the antibiotics seem to be helping we can pick up some more for an extra 3 days, and he also said there is a possibility that it could flush itself out in time.
We are to get all the horses teeth checked hopefully next week and talked to him about it and they have a dentist there who will tranq the horses (my local ones apparently don't and are rough, so they are NOT to touch my horses, period.)
He said if it's not a twig or something it could be the roots of a molar heading up through the sinus cavity, and if it is that will require tooth extraction, but at this stage she is on antibiotics and it's not bad
He talked us through everything and gave us several options, explained where and what shape everything inside her head is, and showed us how both sides of her front sinus (between the eyes) are hollow sounding even though the side her nose snots from is slightly enlarged.
Overall, I will definately be using him in future, very helpful and kind. so the judge that abused me at last weekends show for bringing a contagious horse to a venue with other horses can stick it up her bum, bubbles is not contagious, and is breathing normally. Her breathing rate has not changed at all and she is not having difficulty catching air.
*pokes tongue out*
I know judges are normally concerned if a horse looks lame/sick etc, but she abused the living crap out of me for having a contagious horse at a show. Is she a vet? No. Did she realise that I had already been told before by a vet that bubbles is not contagious? No. Could I tell her that? No, because she would have red carded me for "talking back".
