Horses need their hooves trimmed, teeth floated, vaccine shots, monthly wormer, and proper grooming and exercise. If that is what you are asking.
A horse is a great responsibility, you need to keep a horse fed, a clean hopefully dry place to keep them. They need to have medical checkups, and they need exersize, and most of all they need love.
usually winter when it gets cold out. sometimes for horses health or medical problems.
yea
they are a lot cheaper to look after then a horse because they don't need all the nutrition a horse needs and they don't need stabling.
Yes, there are alot of questions that need answered.
Medical will vary by what is being treated. I suggest asking a equine vet about proper horse care in the event it is wounded or needs specialized care.
Depends on the weight of the horse, the age of the horse, how hard the horse is working, the type of grain, and how well they keep their weight on just hay. The nutritional value of the hay your horse is being fed can also affect how much grain your horse needs. If you are trying to put weight on, the horse generally needs more grain. If you're trying to reduce the weight of your horse, they generally need less or none at all. If a horse is not being worked at all, they do not need grain unless they cannot keep weight on with out it.
Yes, a horse does need a saddle pad to protect it's back and make the saddle feel snug on the horse.
The main thing a horse needs if frequently excercising is electrolytes these are vitamins and minerals that are needed because the horse is losing vitamins and minerals his/her body needs to be healthy.
Brushes, Hoof pick, quality grain, horse grade hay, fresh water. Basic medical supplies - bandages, wraps, disinfectant.
A 13 year old horse is not too old to compete in cross country competitions. The horse just needs to be physically fit to compete. Horses live well into their 30`s now. Your mother needs to accept that things change. If you get this horse into shape, feed it right, there is no reason except a medical one that could stop this horse from doing any kind of competition! If the horse has no medical issues, there is nothing that can stop it, except your mother.
They need blankets in the winter time, so they can keep warm.
