I havent used it on my little ones. But my 2 grown does....it has no effect. I have used Ivermectin and one other i cant remember the name of. Way too much resistance. Im going with Mollys herbals. I have heard wonderful things about the formula 1 and formula 2.
I have slacked off lately on the Diatomaceous Earth as well as i have been very distracted with upcoming move to Tx, but when i keep DE on the ground and in bedding and feed areas, the parasites dont do so well.
If i can go natural, i will do it. I am all for natural rather than chemical if it will work. I do the same with my horses. Chemical wormers are not working well anymore.
