I just got a new horse about a month ago. He was kind of underweight and within a week and a half he was really lookin good - he had put more weight on and everything. He was also so kind and loving he would follow me around and (hes not trained at anything even sacked out) But he would let me touch him all over and I had a saddle on him within 5 mintues and I could about ride him. Since I had kept my other horses about 22 miles away from where I lived I decided to move him to my fiances gma and gpa. Well gpa didnt want the horse and gma did and they never had gotten along very well and still don't. But I moved him there and I had gotten some hay and I told them to give him some hay when mine ran out. They said okay. We had a few nasty storms and rain and such and I didnt have a vehicle until yesterday to go out and see him which has been two weeks. They knew he was in their care. I went to see him yesterday and you could see his ribs, distinct back bones, his bones right under his neck, his shoulder blades, his hips - were all very distinct. How long does it take a horse to get that way? - Also he wasnt himself. He was headshy, he wouldnt let me rub his belly and he tried kicking me, he wouldnt let me brush his tail. Is there some kind of abuse you think is going on? There is a picture of him when he was nice and healthy. Roscoe doesnt seem depressed at all. Just not himself. He's a 1/2 quarter horse 1/4 thoroughbred and 1/4 friesian.
It doesn't seem abusive at all. It seems like an untrained horse that was left alone for a bit and he turned right back into the horse he was. He doesn't want to be touched or fussed with... he wants to be left alone.
Also, it takes a horse a while to get ribby... it also takes longer then a week for them to fill out. Get a weight tape so you'll have a somewhat accurate measure of seeing where his weight is.
