Just curious, why didn't the Arabian's adoption work out? As someone who happens to own both a half-Arab horse and a mostly border-collie dog, my dog is much more challenging and time-consuming than my horse! But maybe it's because my horse is now older, he has become such a solid partner that the challenging memories of his youth have faded, but my dog still tests me every day! Both are so fun, training a young animal whether a horse or a dog is so rewarding! Good luck with your new dog, I still hope you become a horse owner someday!
