Two kind of random questions?

1. Is it possible to get a gaited horse to trot? I found some tennessee walkers and kentucky mtn horses that are really nice as far as confo, temp, and training go, but I want a horse that can trot. Can I possibly get one to trot?

2. Is there any special care for an entirely pink skinned horse. Like should I put horse sunscreen on it's exposed skin (eg. nose)? Should I put a fly sheet that has solar protection?
