Heartland - Season 17, Episode 5: Soundtracks

This is the opening theme.

At night, Katie spends her evenings at her computer browsing through internet ads for secondhand dirt motorcycles, sighing at the pricing.

When Blue hears Jack whistle, the horse gallops over to join Jack. After mounting the horse, Jack demonstrates spinning in place as they speed across the dunes.

Jack hands Amy the reins after telling her that Blue is warmed up. Blue stops as she attempts to spur the horse and ride him. She gives him another push, and this time, instead of following Amy's instructions, he gallops wildly around the circle. Amy and Blue chase after a cow that runs along the fence. Amy is left behind when Blue abruptly reverses course and follows the cow.
