My horse has always suffered from low heels and thin soles compouded by the wrong type of shoeing. After speaking with my new remedial farrier he suggested a good Biotin suppliment to support his work. I researched suppliments on line and discovered that Hoof First contained more Biotin than any others. What can I say - after only 2 shoeings there was a difference in the quality of his feet, after 3 there is a massive difference. My delighted farrier called me over to test the hardness of his feet and I have no doubt that your product combined with good farriery has made the huge difference. A once crabby moving, sore footed horse is going so much better that he has come up through the shoulder so much that everyone comments on how he has grown. I would recommend this product to anyone who has a horse with thin soles or poor quality feet, it really does what it says on the tub!
