I pray that your Bro is over his impaction and can come home.
Colic is always scary. My mare had regular episodes for several years. (Knocking on wood, it has been two years since she has had one.) Several of the episodes required a stay in a Vet clinic.
Getting horses to drink enough water in the Winter is often a problem. My mare loves warm water. She will drink 3/4 of a bucket, several times a day, if the water is warm. She wants it warm in the summer too. Go figure? Whatever it takes to keep colic at bay, I am willing to do!
I saw Brolio for a short visit yesterday afternoon at the clinic. He seemed happy to see someone NOT vet trained and was nosing my pockets with his muzzle on for treats of any kind. He was the only horse there this weekend, so he was a little bored and was staring longingly out the window watching the snow storm and cars slowly driving by. He was content enough that I gave him lots of head scritches and neck rubs, even letting DH pet him.
Last evening I got the daily report saying that he had no more pain episodes that day was no longer on pain meds. Unfortunately, he still hadn't passed the impaction, but it was getting softer and he was leaving some small piles. They were hoping he would have passed it during the day and could start to introduce food yesterday. We'd see in the morning whether or not he'd being staying another night...
9AM I get the morning report, more manure in the stall, still sans pain meds and vitals are still holding at normal ranges, rectal still says not all of impaction gone, but smaller and softer, also nothing in his small intestine (what could there be, he hasn't eaten anything since 8am Friday!). He got to have a small flake of hay, which he ate happily (I'm sure he probably inhaled the thing in 0.2s!!). Plan is to continue monitoring him today with more food being introduced and he can come home this afternoon if all keeps going well!!
Got a call from my normal vet (she was on vacation and also got stuck in the original snowstorm), asking how Bro was doing and apologizing for not being there. I'm lucky I'm in an area where there are multiple, competant equine vets so that should one be out of town/sick/injured/busy another can swoop in to make the save. The clinic has been in contact with my normal vet and has kept her updated on Bro's condition and subsequent treatment.
