Hey everyone, I was wondering if anyone else have dealt with these tiny yellow worms that vets can't seem to diagnose. Apparently they're not showing up microscopically and it's really frustrating. They are moving little worms. She's been treated for tapeworm and roundworm multiple times but still has them. The vet says it's definitely not tapeworm because they are moving worms. Anyone have any idea on what they are and why no one is able to diagnose correctly?
