I am having a problem with strongyles and I have used safeguard, ivermectin and cydectin. My vet came and took a fecal 2 weeks ago and that’s when I treated with cydectin and safeguard. Now today they went from 1800 eggs and 1200 to 3500 and 2800 eggs. She said the last resort was a medicine called prohibit( if anyone has experience using this drug some helpful information would be appreciated). But has this happened to anyone else and if so what did you guys do to help this situation..
