My mare Honey Boo Boo (Bright As A Star, APHA) is like that. She was raised in a show barn as a halter horse and basically her owners put her with a trainer and then never messed with her again. Trainers usually don't have the time to make pets out of the horses in their care, so the horse doesn't really learn to "connect". People comment that Boo is kind of stand offish and are shocked when I say, "OH NO! She's downright sociable compared to when I got her.". I can do anything I want with her, and when she's got a foal at side she allows me to handle the foal all I want and never even looks at me sideways. She's the PERFECT broodie, except she's not a pocket pony. She's not mean, she's just.....lukewarm. Her foals however, are absolutely people pleasers. They are wonderful to handle and they're really good looking too. At this point, there's not enough money in the US to buy this mare. Give her some time to get used to being fussed with. Feed her carrots and apple bits every time you go see her, brush her and groom her and learn all her favorite scritchy spots and make sure you hit most of them every time you go out. Just quit a little bit before she's ready to have you stop and walk away. Leave her wanting more. She'll warm up. She may not ever be your "lap dog" horse, but shire's are a bit big for that anyhow aren't they? LOL!
