Milk jugs with rocks in them.
water bottles with enough scrunch in them so when they bite them it makes a noise.
an old lead rope, mine love to play with these and leg straps and halters they find and can swing around.
Mine never play with actual horse toys, the items we dont want them to have they have hours of fun with.
I had riley in a stall 7 days in August for the fair, water bottles were his main toys, that and putting an apple in his full water bucket and letting him try to get it.
Without my horse, im just human. Without me, my horse is just an animal. But when you put us together we become an unstoppable team!
