“blind” and unstable doe??

Hello everyone, I have a doe with sudden polio like symptoms. I was locking up the does and I noticed she wasn’t in the shed and I found her outside covered in snow (this was one of the coldest days we’ve had in a while). She was out of sorts & confused. I got her up and she was super unsteady and almost seemed paralyzed in the hind end and had a hard time keeping her legs under her. I put her in the barn with a heater and 1 other calm doe and she was acting blind and bumping against the wall a little bit but then she found the food and started eating. She would also circle too. I’m currently researching but thought I would post on here to see if you guys have any ideas. I brought in a doe a few months back from another herd and I didn’t realize but my mom had just started throwing some grain out for the does these past few weeks so i’m wondering if the imported doe is a carrier and the affected one ate her feces while going for grain?
•They’re fed high quality hay from a round with no mold, dust, etc
•She doesn’t have any facial drooping or drool yet
•She’s a 4yr old

 

The only thing I have on hand right now is “high level vitamin B complex” it has thiamine hydrochloride at 100 mg per 1 ml. Online it said to dose at 10mg/kg as a minimum and she weighs about 40 pounds so she should get 2 mls intramuscular?

 

I also have penicillin so should we treat with both to cover either one? Online it said to give a big dose of penicillin but was unspecific in dosage

 

thank you, what would high levels be considered? Like 5mls?

 

Thx, what would a high level be for a 40 pound goat? 5mls?

 

We don’t have many goat vets but we’re gonna bring her into one tomorrow. Thank you

 

how much banamine?

 

Thanks! She’s gotten considerably better since last night so I think we caught it early. Sub Q or in the muscle ?
