I'm having a slight issue right now with Sky and her weight.
I bought her in September, and since her previous owner said he had just wormed her I waited 12 weeks to worm her again. In December I wormed her with invermectin and she looked good through the winter. I let time get away from me and didn't worm her again until two weeks ago, making it 16 weeks since the last time. What caught my eye was how wormy she really looked. I've been noticing lately that I can see her ribs, when I couldn't before, and her back was bony but at the same time she has a belly.
I wormed her with Safeguard this last time because that's what was next on her rotation, but two weeks later I am still not seeing any improvement on her wormy belly. Shouldn't I be by now, if the wormer worked?
I already plan on getting a fecal egg count, but I just had to ask if it was normal for a horse to get so wormy just by going over a few weeks on worming her? And should I in fact being seeing results already? After the fecal egg count, when is it ok to worm her again?
