Extra Label Disclaimer:
A few of the products on my site are FDA labeled for farm animals like pigs, cows, and goats. I use them all for my sheep under “extra-label” application. This means I have a good relationship with my vet who oversees my use of these supplies on an “extra-label” basis.
As a legal disclaimer, be sure you have the same vet oversight when you are using products for sheep that are not FDA labeled for sheep. If you do not have that vet relationship understand that you alone are liable for whatever happens if you use these products for your sheep.
