^^yeah, asking for a dozen things does seem excessive.
Maybe change out mounts if doing lots
of work or riding (pony express comes to mind). Proper recovery time before more strenuous work.
Regular inspections of legs, feet - keep an eye out for developing problems.
Making sure the saddle fits the horse well, and paying attention to weight changes that could affect this.
Proper training - hobbling, ground tying - a cowboy doesn't want his mount wandering off
Making sure the task suits the horse - making a horse a plow horse versus a riding horse.
