I wished it was a clearer pic of the dog to see what breed it is. Normally it's the border collies that excel in agility but that isn't a border collie. It looked like a pointer to me.
Speaking of agility. My husky years ago had a pot belly pig in her obedience class. And Fred the pig went onto agility racing. He did very well at it too and did very well with obedience training. Here is a pic of Fred in a race in Oakville.
