Well, I have first hand experience that not all colics can be fixed without surgery, as I have had to have 3 colic surgeries on 2 different horses. The one (big horse) who had two surgeries survived to a relatively ripe old age, but the mini (whose surgery was paid for by a program similar to the Smartpak one) did not. Other than those three very serious colic episodes (which would have been fatal without surgery) I have rarely had a "simple" or "mild" colic in over 50 years with many, many horses. I highly recommend these colic programs such as Farnam's and Smartpaks, because the whole point is that their products help PREVENT colic. A vet pointed out to me that when he first started offering the Pfizer's Preventicare Program, (which no longer exists) he noted right away that his practice was ordering fewer supplies to treat colic. That sure sold me.
