Sad Zoe, confined to a stallWhat a roller coaster weekend! I went from a fabulous Saturday ride to a colicky Zoe on Sunday.
Barn owner C called Sunday around dinner time to tell me that Zoe was laying down in the mud - even though it was feeding time and all the other horses were waiting at the gate. I rushed out to the barn, we administered Banamine (a horsey NSAID) and began watching her closely. She was confined to an interior stall - which she found terribly upsetting since it meant she had to be separated from her pasture buddy, Toika.
The colic did not appear to be life threatening, and after a call to the vet I decided to just keep her in overnight so that we could monitor her water intake and BMs closely. (I swear it was just like having a sick baby; I've become obsessed with the contents of Zoe's stall just as we were with our babies' diapers!) I could see that she was in pain (high respiration rate - around 90/min. at one point!) but she had calmed some by the time I left (respiration rate down to around 40-50/min. - keep in mind that 15 to 20 is more normal!)
I went out early Monday morning and Zoe appeared to be much, much better so I decided to let her go on out to the field to join her buddies. As I was closing the gate behind her I told C that I would hold off calling the vet unless Zoe laid down....which she immediately proceeded to do. It became immediately obvious that Zoe was still suffering so the call to the vet was made and she came out to the barn within the hour.
When Dr. Adams arrived she didn't think Zoe was the sick horse. She appeared to be calm and relatively happy walking around with me. But upon examination Dr. Adams could tell that Zoe was indeed off; her heart rate was over 50 (normal is usually 30ish to 40) and there were no gut sounds at all. We all suspected an impaction.
But an examination showed no impaction, only a slightly enlarged right ovary. Huh? So what was going on? We decided to draw some blood to see if there were any kidney or liver problems. During all of this, it was discovered that Zoe has a huge fear of needles and requires a twitch to keep her calm-ish and still-ish and that she reacts to one of the sedatives in a not-so-great way. She began breathing super-fast just after it was administered - kinda scary, actually. The blood tests showed us that Zoe is very anemic - but why? Possible causes include tapeworms, ulcers or an internal melanoma tumor. I'm leaning towards the ulcers, myself, and will begin treating her with appropriate supplements once we get this current colic stuff under control.
Zoe was kept in her stall another night and fed small amounts of hay. When I arrived this morning she appeared to be her old self, although there still was almost no poop in her stall. As I was standing there, wondering what to do she proceeded to poop, pee and pass gas. Hallelujah! I decided to let her go out to the field where she would be happier. I talked to the vet at 8:30 and told her the good news and we laid out a plan of action for the anemia. I was so relieved to have survived our first colic episode so easily.
And then not 15 minutes later C calls to tell me that Zoe is laying down and getting up repeatedly in the field again.
Another call to the vet, I leave work, meet her at the barn and another examination. But all vitals are normal. Gut sounds could be heard in all 4 quadrants. We have no idea what is causing Zoe to colic.
We will continue to watch her closely, but have decided against stalling her any further - it just upsets Zoe too much. (We'll work on breaking her emotional dependence on Toika later!) I got some more Banamine to help make her more comfortable and also purchased some pro-biotics to help with any imbalance she might have in her stomach juices. I'll start her on something to guard against ulcers and too much stomach acid soon (Uguard, perhaps) - Zoe appears to be one of those high strung horses that may be prone to these problems. Not surprising considering her history and her breed (cougar attack, 1/2 Arab). I also picked up a tube of wormer to get rid of any possible tape worms - although I really don't think that's the issue here.
Right now, I'm just tired. I'm looking forward to not being constantly worried about my pony.
