Not sure what a fecal float is but will look it up. Thank you -update, it looks like you need to get set up with a microscope to see any parasite eggs. This will take us a while to get set up. It also looks difficult to actually spot and identify the parasites. Are there any other ways to test for internal parasites?
Calling around you may be able to find a vet that is willing to run a fecal float. They do run about $50. Any vet that treats dogs and cats CAN do it. It is just most won't. It takes a lot of looking to find one that will.
