I have been using Forage Only for a couple of months now on two TBs that can be slightly hard to keep weight on. They are 16 and 17 years old, in great health, regularly get their teeth floated, in full work…but, BOTH have had choke episodes on the Forage Only.
The product claims to be safe to feed dry. I have tried it dry, slightly wet and soupy. The pellets are small and break fairly easily, not much different than a typical grain pellet in size but slightly harder. Neither of these horses bolt their feed or are particularly aggressive eaters.
The one that had the more serious choke episodes (3 total, with an emergency vet call on the 3rd, the first two passed quickly) was only getting 2 qts of Forage Only, so not a huge amount of feed to begin with. After choke episode 1, I started adding water to the product and have increased it to a fairly significant amount for a product that can be fed dry. On the plus side, he likes it and it has put weight on him, plus, he is prone to dry itchy skin and that has noticeably improved - no more tail rubbing!
The other TB had only one very mild choke episode. He gets 4 qts of Forage Only, so a greater amount of feed but is a slow eater. He seemed to really like the product dry (he was getting super sloppy beet pulp and alfalfa pellets prior). I now get his slightly wet and he has been fine. The Forage Only has greatly reduced the volume of feed he has to get in a day while putting weight on him. Plus, it is super palatable to him. So, overall, I am very happy with this product for this particular horse.
In summary, I like the make up of the Forage Only and do think it helps with weight. I do find it easier to feed than beet pulp and/or alfalfa pellets, but I would NOT feed it dry, which is a bummer.
