I have a gelding 30 years old who was suffering from constant diarrhea. Nothing fixed it ... for an unknown reason I read the bag decided to give it a try, grabbed a bag and started using it. Thankfully it has fixed the problem. I have been using it for months with him.

I have 2 subscriptions, and they need to be paid with different credit cards. This is not possible on their website, so I have to remember to go in and keep changing the credit card. Also, there appears to be no way to apply a gift card to my subscriptions. Besides that, I can't just go to the website and shop because whatever I put in my cart never shows up when I go to checkout. Certainly leaves me in a lurch when trying to shop online or take advantage of their shop online/pickup in store promos.

While I have heard the treats are beneficial, my horse literally spit these out.
