What do i do If I do not have a vet in my area that does Centrifugation worm tests?? I do not want to worm unless they need it. I have one that is pregnant so I am leery on worming her at all! Should I just worm occasionally to be on the safe side? Also do not know whether to use a paste such as fenbendazole or the evervectum shot instead for the mengineal worms? Is there a way I can test myself?
