I’ve got a horse that has been in full time training. He went to the trainer with a show coat and 30 days later he has now blown his hair coat and looks like he is in the middle of winter. We’ve run a CBC which shows a few low normal ranges, which we then gave him a PowerPac. My question is, what makes a horse blow his show coat in this manner? Tommy and Candice
Dear Tommy and Candice,
A physical examination, bloodwork, and treating for parasites is a good approach, but your horse may have suddenly lost his coat simply due to stress. Although hair grows in cycles that are related to daylight and temperature, the quality and quantity of a coat is also affected by nutritional plane, certain health conditions and even stressful episodes. Since your veterinarian is working on ruling out medical issues–and I’m assuming that the training barn is correctly feeding your horse–he may just be reacting to changing barns and starting a new exercise program.
