We have a five-week old QH colt. He has had diarrhea for almost two weeks. He is not dehydrated. He has a lot of energy. His dam gives a lot of milk and he is nibbling at both feed and hay (Vitality 12 and good coastal). We have wormed him with Safeguard and have been giving him Imodium and Kaopectate. Other than the diarrhea, he seems to be in great health. He runs and bucks and has a healthy appetite. We are very frustrated at this point. What else can we do for him?

Thank you.

Hello:

Leave him alone. The diarrhea will most likely be safe limiting in this case. There are a number of factors that could be in play here:

1) rich milk of the dam
2) just good quality grass
3) hormonal changes in the mare

Now, at any time the foal starts to look sick then I would be concerned and call the vet but as long as he is acting normal don’t worry.

Thanks,
Dr. Lowder
