Well, I guess I'm not going to be very popular here. I think everyone's frustration is showing, and we need to focus on Darla and be positive in our approach to her care.
Jess, this is not your fault. We all know this is a new mare to you, without much history to go on, and you have been doing what you would normally do for a pregnant mare. I cannot say that you are not doing everything you can for Darla, because I think your trying very hard. I know you love her, and I'm pleased that you took the time to get the vet out a second time. I'm also glad that he found something wrong with her this time, and is PARTIALLY treating it. But, I think you deserve MORE from the vet than he is giving. The VETS are letting you and Darla down, and you're paying for it, so insist that you want some answers -- and want them soon.
By the way, Banamine takes about 30 minutes to work, and why didn't he give some type of anitbiotic for infection?
I'm sure no one means to lash out at you, but rather the situation. Everyone here has been very concerned about Darla, and the length of time she has seemed to be struggling with this foaling--or whatever it is. YOU have been a good momma, and I'm pleased that you got concerned enough to call out the vet a second time.
I know that you're feeling it too -- as this has gone on for a long time and you've (we've) been up and down watching her and being concerned about her. I would insist that he come sooner than later, since you've been tiring yourself out for over a month. Just tell him you don't want to wait any longer, and you want some answers to her apparent discomfort and problems.
I would have a further talk with him, just to give him a heads up and seek more of an opinion. You need to let him know that you want this taken seriously and need some answers. Give him the rundown:
1. She has been having this discharge for over 1 month, so it's not a mucous plug--what is it? Shouldn't it be cultured?
2. That she has been showing signs of foaling for a month or more with no furtherence--no foal.
3. That she has been showing her foot problem and painful feet for the better of the past month, as well. Gingerly walking and spending an incredible amount of time laying down.
4. Tell him you are concerned, that she is sometimes quite off her feed, non-pooping for almost a day at a time.
5. Give him her temperature records and a description of what her udder changes have been with dates.
6. I would ask him to do some routine blood work, to check kidney and liver functions, etc., and tell him you just want an overall health check, because you feel something just isn't quite right. I personally would let him know ONCE HE GETS THERE, that you have asked him for his professional opinion twice, and now it's time to test and really find out. I'd tell him he can "waive" his farm call since he's already gotten one twice for essentially nothing but "observation." He doesn't even know if the abscess is infection and/or what kind of bacteria is at the route cause.
I'm sure I'm forgetting things, but do a full review of the thread so you can give "dates and information" that give the full picture of what's been happening. That will help him in working on a diagnoses and let him better know Darla. He's seeing a pregnant mare and a concerned owner -- but he should be seeing "the horse" and the fact that there is something there that just doesn't seem quite right to you.
I'm a bit perturbed by both vets, as I think they have let you down, and not done true examinations of Darla. They are "guessing" without testing, and that why we call for a "professional" opinion -- all WE can do is guess -- the VET is supposed to test and diagnose. Don't let him off that easily -- he is not doing what you are paying him to do.
I know you're frustrated, and believe me -- no one's frustration is really aimed at you. You have been monitoring her udder, her temperature, etc. You have been doing things, and your vets have not been helping you. I would call him again, and tell him you want him back out there tomorrow to do a diagnostic exam so you know what you're dealing with.
Remember, the vet works for you. You're paying for his expertise -- not guesses. Darla's health is at stake, and you want her to be given the vet care that she deserves. Make him give you answers -- and I know that you will feel better and you'll know what is going on with Darla.
