How much commitment is needed when keeping a horse?

A lot! The owner will have to be there first thing in the morning to feed and look after the horse, then later in the day to feed again. They will also have to organise excercise (riding), turnout and care for it at some point during the day.

If you don't have that time available, you can loan the horse out for a few days a week- the loaner will probably contribute towards the horse's welfare. You can also get assisted or full livery, where the yard owner/grooms look after the horse at arranged times (however this can be expensive).

You also have to consider money - DIY livery (where you look after the horse yourself, in a stable with access to a field) can cost around £30 per week, and assisted/part/full livery will cost more. Your horse can live out (this will be less) but it will have to be hardy and a good doer (doesn't need too much feeding).

There is also the cost of feed, insurance, vet bills and farrier bills to consider, as well as initially buying the horse.

It is important to get advice from a knowledgeable person before buying the horse.
