Just give it some water and throw in some hay. We saw a lot of tooth and hoof problems, because the owners had NO idea.

It seems a lot of people have more of a functional attitude towards horses, instead of a pet relationship. They seem almost entirely interested in what the horse can or cannot accomplish, do for them, etc.
What you have said here is very much the crux of the situation for horses in general. That is why I mentioned that the horses with "jobs" to do are often the best kept too. Proper feeding, hoof care, teeth care, grooming, etc., are vital for a horse's health. A horse with poor foot and teeth care can, understandably, develop behavior problems due to discomfort, pain, lameness, etc. People get a horse and do not take care of their feet, their horse becomes lame, they find them unable to ride, and they dump them off and replace them with the next. It is not like keeping a dog's nails trimmed, hoof care is essentially life and death for a horse in the long run. Same with teeth care, if not properly done then they eventually lose the ability to eat and stay nourished.

Pictures and videos of neglected horses are not hard to find. You can find them all over on horse ads for sale even. One might think it is just the worst of the worst, but it is shockingly common.
