10% of Henny's bloodlines is the the Poco Bueno bloodline. Sure, he's stubborn sometimes. He was pretty difficult to halter break according to his breeder. Though I've not thrown anything at him that he's absolutely said "no" about. He is a quick learner and will do what I ask him. Sure, he may think differently now after his accident. He needs a reminder more often than he should, but he picks it right up again like a pro. He's an absolute love bug and will follow you everywhere. He string tested to 15 hh even, which I don't really consider short. I'd actually prefer him to fall a couple inches lower than that cause I like 'em short.
