Great Product! When I purchased my mare she was at least 200-300 pounds underweight. She is back and in show shape! May 8, 2013
seems to really like it We were able to regain weight lost during the winter which also resulted in a happy horse. May 1, 2013
Needed to Gain Weight I had a show gelding who didn't slick off very quick this spring and he was alitte thin. I started adding Smartshine and this product to his daily feedings. Within 1 1/2 months there is definitely a huge difference. He still needs to gain alittle more weight but he is well on his way to looking great. April 30, 2013
Smartgain Excellent product. Moved my horse from NY to NC and the change made him lose a lot of weight. He is a Thoroughbred so always on the lean side. Within 6 weeks of using Smartgain there was a huge difference. He has filled in on all the sunken spots. April 29, 2013
It Works... Ordered Smartgain 4 for senior horse (30) who was losing weight no matter how much supplements I fed. Horse could normally only eat leaves from hay and not stems. Was feeding pounds and pounds of beet pulp and alfalfa pellets to supplement with less than desirable results. Started using product once a day with 2 pounds of grain in addition to normal alfalfa hay ration and it has stopped the fast weight loss and is slowly putting some weight back on. Horse digests feed much more efficiently as is evidenced in daily stall mucking. Smartgain 4 is worth a try for any hard keeper, especially senior horse. April 23, 2013
Smart Gain Review After trying CocoSoya, it was recommended I try this product. I have five horses, two of which NEVER gain weight and have been checked multiple times by vets to see if there is a health problem - nothing has been found. I have tried many supplements and different types and brands of food but they don't gain weight. They seem healthy but just look like they could use some "groceries". Unfortunately Smart Gain did nothing for them. April 18, 2013

To Clip or Not to Clip I've heard that body clipping in the spring is "too late" because you're clipping over the newly growing in coat... What do you think? What's the best body clipping schedule? - Jessica N., Charlotte, VT
