My sister and I went and looked at a horse today that she is thinking of buying. The people described the horse as being really quiet and gentle..they said she walks fast but other than that...shes really good. Well when we went and looked at her she was stalled up. She tried to push past the man to get out of the stall. The man then told my sister she could come back tuesday and ride her...but my sister insisted that he ride her today. She would not stand still to be saddled...he finally got her up against a wall to get her saddled. When he went to mount her...she wouldnt stand still either. While riding....she seemed a little spirited...he rode her down the road a little ways. The whole time she was nickering. It seemed as though she started acting up when he got a little ways away..but we can't be sure because he turned her around and came back towards the house. He said that she will be better when she hasnt been stalled up, and asked us to come back tuesday and ride her. My question is...can all this behavior be explained by her having been stalled up? We do have horses...but we don't keep them stalled...so we don't know. My sister is looking for a really really quiet horse that she can just jump on and ride. I will be riding with her most of the time...but she does want a horse that she can ride by itself if she wants to. The horse is 10 years old if it matters. I personally feel that those behaviors are red flags...but idk...should we go back tuesday and give her another chance or look elsewhere?
