Elvis wasn't feeling well this morning and had diarrhea and has gotten sand colic when ever the autumn/winter and spring/summer changes occur (this hasn't happened since upping the hay intake) I thought I would see how much sand was in his poop. I took a large handful from 2 poops that was on grass and put it into a 1 litre icecream tub and filled it with water and waited a few hours and then flushed it out with the hose. When it was clear there was a bit of sand in the bottom of the container, but there was also 10 red worm/blood worm eggs as well. (I am going to redo the test again tomorrow with just one piece of poop for sand content.) I googled 'horse worm egg photos' and they look like the eggs being sold as red worm eggs for growing your own fishing bait. Elvis is wormed according to the Virbac worm control program during the 3rd week of the designated month, should it be at the start of the month. He was stomach drenched for worms earlier in the year. I read someone lost their horse after worming, should I give him Equimax now and then give him Strategy-T (which is due next week) in 14 days? Sorry its such an epic!
