I have a quarter horse mare who I have worked very hard over the last year to developed a bond with & we were doing better & better. We've been riding on the highway alone & making all kinds of progress! She was my only horse until a month ago when I bought this pony. He is a cutie. Very kid broke & lots of fun except... He is totally buddy sour! Things go great as long as I bring him with us but if I don't he whinny’s over & over & every time he does my horse freaks out & wants to run to him. It's a constant struggle. I wish I could put some kind of shock color on his vocal cords or something but no I know that would be cruel. They do it to dogs though. Anyway I was wondering if anyone could give me some advice.
