Lakota coliced pretty bad a couple weeks ago. The vet came out and pumped her with banamine and mineral oil and the next day I gave her quest, because the vet suspected ciathostomes. A couple days later she had mild colic again and we gave her more banamine and I walked her for an hour and she was fine. She seemed a little off but the vet said that can happen when the larva are dying and being passed out of the GI tract.
A few days went by and she was doing much better. We went on a trail ride and she was fine and happy. Yesterday I got a call from my BO and she said Lakota was acting very strange. She said she was lethargic, refusing to eat or drink, and was standing facing walls alone. She said when she turned her out yesterday morning, she walked past the round bale, into the shed, and stood there alone staring at the back wall.
She checked her temperature and it was fine so the vet said to make an appointment to have some labs done.
Last night Lakota was apparently running into things. She didn't eat her grain or hay, but did knock her water bucket over and break it in half, eat a bunch of the wood in the stall, and eat the plastic off of her grain bowl. (I was updated about this at 11:30 this morning) The BO said she seemed to be doing better, she was walking faster, but she was pacing around her dry lot, still refusing to eat.
I was out there by 1:30 and when I found her she was bleeding from her nose and/or mouth, was walking zigzaggy and unable to maintain her balance. She was wheezing and her breathing was extremely labored. I grabbed her and put a halter on, and she had a blank and unresponsive look on her face. I called the vet immediately and she was out within 30 minutes. During that time, Lakota progressively got worse, stumbling, walking into things, sweating, and falling. She had been able to get herself up a couple times, but the third time, she flopped and couldn't get back up.
Her head looked swollen, like her brain was bulging through her temples.
The vet showed up and gave her banamine and a steroid shot. Took her temp and it was 105.5. She was really struggling to breathe, so the vet tried to scope her and couldn't see into her trachea. She did a tracheostomy to get her breathing better and I just sat in the snow with her by her head. Her mouth was foamy and her eyes were bloodshot. The vet was able to scope her this time, and said that there was a lot of edema around her trachea, which could cause the breathing problems.
After an hour and a half, her breathing had slowed a little bit, but she was still not doing well. Her temp was still 105.5 and her gums were blue. She looked like she was in shock and wasn't getting better. Her breathing started to slow and I rubbed her head and told her it was ok to go, and within a minute, she died.
The vet says she'll be in touch and talk to some other vets and see if they have seen anything like this before. She said the symptoms just don't add up. The fever, the confusion, the edema, the colic...it doesn't make any sense.
If anyone has heard of anything like this before, I would like to hear your story. Thank you for your responses.
