Funny enough, Succeed did work for about a month to clear up his GI problem. But it was not worth it in the long run to keep him on it to me with the personality change. I fed the supplement for three months from January to March 2012. The first bucket I got from a vet supply and then I was so excited after the first month to see it worked. I kept him on it for three months. I am in no way an expert on ingredients so for that answer I couldn’t say what may have affected him.
It seems to work for a lot of people! So it may be worth it to give it a try. I had called a Vet at in a very prestigious PA vet clinic and she said in all cases of GI problems that are severe they start all the horses with Succeed. The personality change is rare but it can happen.
