There used to be this big TB at an agistment place and there was once a little dog wearing one of those jumpers (it was winter) and the horse picked him up and tossed the little dog about 3 or so metres. It was very impressive (the dog impressed though, at least not positively).
Some horses don't like little animals, and if your horse doesn't exhibit directly around you then its going to be very hard to train him out of it.
A horse I once had was perfect with dogs, but then my little dog was eating his spilt food and the horse smelt the dog who then, out of shock, lightly bit the horses nose and since that day that horse did not like dogs. Maybe a little incident occurred between a little animal and the horse.
I would just advise to keep the small animals away from the horse, its too risky having them around as a horse can easily hurt or kill an animal that size.
