I'd like to change his name, but he does seem to know it and responds somewhat to it during training. So, I'm thinking of names that start with "D" at least, or that sound like "Dan". Digby came to my mind yesterday and seems to suit him. "D'Artagnan" may be a bit too noble for him - LOL!
Here are a couple of pictures to help you out:
Personality-wise, he is skittish and worried about new things (he wasn't handled hardly at all prior to going for harness training in April/May for a month -- I bought him while he was in training), but he has a great mind and is coming along with the work I'm doing with him. He now longes, can be tacked up & harnessed, drives single and in a team (I've only ground driven him so far, but the trainer had him hooked to a wagon many times), and yesterday he had his first successful trim with a farrier (I have no idea if or when he was done prior to me buying him).
Thanks for any suggestions you might have!
