Being a Thoroughbred, she has very thin skin, so every little fly that lands on her makes her very irritable and angry. Her feet were starting to chip very easily from stomping due to the flies, no matter how much moisturizer I put on them. Whenever I started grooming her I always had to watch out for her hind feet because she would just kick violently at the flies. I started doing some research about different fly supplements and I came across Bug Check. I started reading the reviews on SmartPakEquine.com and there were people from very buggy states saying it worked like a charm, so I got the SmartPaks to try it out. It really does work! All in all she is a very happy horse this summer, and I owe it all to the SmartPaks! So thank you SmartPak for making it easier to give her the supplement and easier for the people who feed her. All they have to do now is open a Pak and dump it in her food. To sum all this up, SmartPaks are great if you are boarding, or even if you aren’t boarding and running a farm yourself. They make the job more proficient and quick, so you have a little more time to spend doing something else other than measuring out the supplements for each horse. So once again, thank you SmartPak! It is an awesome concept!!!
