Boots

Boots is Luke's horse.

Georgie runs into a famous old trick rider at Maggie's who is very rude to her. Georgie tells Jack and Amy and they tell her about her past and about how she recently had a rough time when her husband died. Georgie and Wyatt try to track down Boots to help make her feel better.

After discovering Luke's connection with Boots, he's the only other person Boots chose to go to other than the trick rider, Amy makes an offer to buy Boots and keep her at heartland for when he visits.

Jack later teaches Luke to ride and get over his fear of riding, he then quickly learns to love riding and enjoys spending time with boots, practicing everyday.
