He is voiced by Dan Hennessey.
He is a blue dog of indeterminate breed, and his Belly badge is a red heart-shaped tag hanging from a collar.
While loyalty and faithfulness come standard on all of man's bests friends, Loyal Heart is an exceptionally true blue friend in the most literal sense. He's perfectly content to either doze in the posies with some of the gentler Cousins, charge howling into a fight if some bad guys rear their head, or simply provide some companionship to a person in need. This multifaceted canine may not win best in show, but he's got it all where it counts.
