It's really strong and stinks. Mine wouldn't touch it so perhaps you should ring up and get a sample before shelling out for a full tub.
Don't know if it works as could never get the pony to eat more than a pinch !!!
introduce it very gradually and they will eat it. my horse has sweetitch and it did seem to make him very comfortable. I beleive global herbs also offer things like mint supplements which help get fussier horses to eat the more smelly supplements like this one.
It smells so bad - like really strong curry powder. Mine ate it ok (but he eats ANYTHING!) but TBH I didnt notice any difference so stopped using it. I was mortified when I first opened the tub - there was a tiny bag in the bottom!
