That depends on what Harvest Moon Wii game you are playing. If you are playing Magical Melody or Animal Parade, yes you can have more than one Horse. You might be able to have more than one Horse in Tree of Tranquility but I'm not sure.

No, a narrow bit is more severe than a wide one.
Having more than one horse can help to keep the horses company, if they do not already have a companion. These companions don't have to be other working horses. For example, you could use donkeys, sheep, cows, goats, mules, asses or horses that are retired, permanently lame or injured or not suitable for work instead. Also, having more than one horse can help when in serious competing. For example, you could have one horse for each discipline, or even an extra horse for amateur breeding, or just a horse that will help to teach a younger or less experienced horse. But keep in mind, horses are expensive, and buying more than horse when you only have the time and money for one horse is really irresponsible.
