lurker revealed/ my case study/ diarrhea ?
Ive been following this thread since it started with optimistic excitement, the reason being my 20yo Trak gelding William. He has been described as ‘the itchiest horse ever’, worse in the summer, has had a few bumps that rubbed raw (the hubby asked what they were and I cassually answered bug bites), some hair loss on the neck, and has tiny skin tag looking things that I seem to recall one of my Pony Club HM judges saying back in the day were signs of worms (NTW’s?) that could be treated with ivemec (this is 20 years ago?).
Regularly wormed with rotation of chemistries, but I will admit no PP (will be adding this for my herd now though). Also have noticed vision ‘issues’ over the past year, with increased spookieness (vet examined and found nothing other than slight age related scarring). Recently started itching tail into a rats nest. Reading this thread I started to put things together…
Double dosed with ivemec last Sunday, on Tuesday he had what looked like fire ant bites on the midline of his belly, across his sheath and down the inside of his thighs- VERY itchy. On Weds both back legs were swollen, although no lameness. Ice/standing wraps resolved the swelling buy Thurs PM, although still itchy. Due for second double dose this week. Based on what I have read about the adult worms and life span, will likely continue dosing with Ivemec at frequent intervals for a while.
I read all the studies posted so far, one of which said something along the lines of the majority of the older horses tested in KY were positive for NWTs (20yo is older i think), and have discussed with my sister who is in her final year of vet school. We think it is a possibility that NWTs are at least part of Will’s problem (if they are the reason for his vision issues and those resolve than that would mean he would be able to resume his role as my dressage schoolmaster).
I do have one question though- I did not use Equimax because both times I have used that with him in the past he has had the worst case of explosive diarrhea in a horse that I have seen. I have used other dewormers, including Quest Plus and (obviously) Ivemec, without that reaction before, so I don’t quite know what triggered the reaction? As another poster asked earlier, I wonder if anyone else has seen diarrhea with Equimax before (single or double dose)? None of the studies I read mentioned it… any ideas??
Thanks to CM and ET (and little D) and everyone else for continuing our education!
