We have a horse here now that was gradually abandoned. This girl bought a two year old stallion (and she was MAYBE an advanced beginner, and he was very green) and after a bit, she got dumped and it scared her. So then she quit riding and only popped around once a month to pay board, and didn't even stop at the barn to see the horse, much less do anything with him. After a few months of this, she bailed and never came back. That was 11 years ago. So now it sends up warning flags to me if the owner can't even make time to see the horse once in a while. To me it says they don't truly care what is going on with the animal if they can't even stop by a couple times a month. I know things come up, but I would think they'd still be in contact with the BO to see how the horse is, even if they can't come out. I have one here now that was terribly abused by a barn where he was supposed to be in training, and his owner didn't check on him for 6 months. When she finally went to visit him, he was all but ruined by these people, and has been on a LONG road to recovery ever since. I wouldn't be able to stand not seeing mine at least a few times a week, if I had to board them somewhere - I would worry myself sick!
