Ah I want to be really clear I use Fenben for my livestock chickens as a dewormer. So the dosage is very low either 5-10ml per chicken oraly or I may do up to 2 tablespoons in a large 5 gal waterer. For larger animals you may want to do a little more research on your end.

Fenben is marketed to different market segments and animals the "suspension" ratios from what I see is the same accross all products, its just that some products are designed or flavored to target a certain critter. For example the products for horses are usually sold in pre measured syringes or flavored paste to make administering easier. It's also included in food or treats and even in a large gallon size as a drench to just pour over the targeted critter.

Best of luck
