Are there situations where you believe it is not ethical for animals to be used to benefit either humans or other animals?

Horse that are best for 8year year old girls

The best horse would probably be a pony if she or he is short a forgd horse or a Shetland pony would be fine but, if the 8year old girl or boy is tall for it's age and looks like a 12year old I would try riding a horse. For a beginner don't go for the fancy horses go for the most know horses to begin with like a pinto, quarter horse, or a paint try to start with a basic horse first then move on to a more you know popular horse i'm still a beginner so I have a quarter horse who passed and a paint but, i'm more of an expert now so that's why I have a little of a popular horse.
