My pony had undergone laminitis. I have to follow so that it does not take weight. I had big bill veto. And the fact the park was not enough and the mare was upset. For three weeks, we have provided with the muzzle, she lost 80 kg and Marshal was even surprised. So, she is much better, we can control it with the seasons and weight gain. More practical and does not need to be enclosed. Lower costs veto in perspective! Compared to the price of the muzzle, do not hesitate to buy it!
