Okay, I'm at a loss here and need some advice. My daughter's little racking mare Blackie has had very loose stool for quite a while. I would describe them as cow patties. She's lost roughly 100lbs over the past year. She eats and drinks just fine, but the weight was slowly coming off. I had the vet out on the 13th of this month, teeth were floated, blood was taken and poop was checked. Blood came back fine (low protein levels but not out of the norm). Doc said from his experience it looks like encysted strongyles (stubborn little boogers).
So.. advice given and taken by me, Panacur PowerPac on all the horses, begin to switch daughter's horse over to a higher fat/protein feed. The last dose of Panacur was given on the 20th. I'm in the process of switching her feed but that's slow going for obvious reasons. My concern is this... I expected her to continue with the runny poop while I was giving her the Panacur, but for the last week and a half now it's not cow patties anymore, it's like someone has turned on a fire hose out her back end, pure liquid projectile sewage is how I would describe this.
Yes, I have a call into the vet but I would like other's opinions and experiences with this. Blackie is in her mid-twenties, pastured 24/7 (new grass coming up as well could be a contributing factor, but this is just...explosive). She's eating, drinking and acting normally, not emaciated or dehydrated, just don't stand behind her!
