What’s the harm in letting a horse which does not like to follow go first? Some horses want to lead. Some don’t want to lead. Some don’t care.
No, we don’t like to lead. We follow. but we’ve been out on trails with those who freak if a horse passes them. (Note to selves: Don’t crow hop through the “herd” when they stop suddenly after trotting.)
If there are to be rigid rules of who does what on trail rides, the rides won’t be much fun. Sure, an organized trail ride should have rules, including who leads and when. But rides out of the barn need to be fun, not tense. Control freaks should not be in charge of pleasure rides at the barn.
Good thing for OP that the fluffy snow was right where she needed it to be.
