HELLO! I am in need of some help. I have a filly that I have dewormed regularly all her life. She is almost a year old now. I took in a fecal sample to my vet and had them spin it down and look for parasites. (this was about a week before Christmas) She had 2 strongyles and nothing else. I dewormed her to be safe. Today, I went out to feed and saw her defecate. Just out of curiosity I took a gander and saw what I now know to be round worms (large adults). I JUST dewormed her 2 days ago with Ivermectin but am concerned she needs to be dewormed again for the roundworms. I have been struggling to keep her worm free since I got her and thought I was doing ok. I deworm every 2 months (if not sooner) and take in fecals to target deworm. I am at a loss for what to do. I have heard of people using daily dewormer on big horses, would that be a possibility? PLEASE HELP!
