I have an eight-year-old cob gelding who was quiet and well-behaved when I first bought him, but now, every time I take him out, he bolts and tries to run home. He even does this when ridden out with another horse. I have had him checked by the vet and tried him in a variety of bits (he seems happiest in a pelham). He lives in a quiet field with my old pony, and is fine working in the school. He doesn’t seem afraid of any particular sights or noises, so I am not sure what to do next. Can you help?
