Being an owner who boards their horses, be very critical of WHERE you board. I prefer stables where someone lives on-site. If you are lucky enough to find a place where the owner / manager really cares about animals, that is a big plus. A couple of stables I have boarded are strictly in it as a business and don't do the little things (like put antibiotic cream on a scratch your horse picked up in the pasture). Make sure the place is safe (no barbed wire fences, pastures are free of debris, boards don't have nails sticking out, etc.). This seems pretty basic, but you would be surprised at what you will find as a "boarding facility". The more potential accidents you can avoid, the fewer vet calls. Here are a few questions to ask the owner / manager:
What time do they feed? Is it the same time every day?
Does the same person feed every day?
Do they charge extra if your horse needs daily supplements or medicine?
Do they charge extra to blanket in the winter?
Do they charge extra for putting on fly masks?
Do they have a tack room you can use and how secure is it?
Do they provide or require regular worming of all horses?
Do they charge for trailer storage?
Good luck to you. It's a wonderful experience owning a horse but be cautious about who you entrust your horses well-being to.
You should go to the Boarding barn and see if they offer lessons. By taking lessons you will be able to see if you like the barn and the people who operate and board there. You will learn about care and needs for the horse. This will also give you a heads up on possible horses for sale that fit your needs.
If you are under 18, try to find a 4H club or similar horse club. These can be very informative and most times you don’t need a horse to join.
