First of all, I know this activity is frowned upon and can unfortunately be harmful or even fatal to horses and ponies. It's not something I do but I confess to not fully understanding the harm that can be caused. I know grass clippings are bad news but what about 'traditional' horsey treats like sugar lumps, Polos, apples, pears, carrots and so on. In what way are these not good?
Thankyou.
