Best guess is that Harley is a Labrador Staffordshire Terrier mix. And he's ten years old. He's a mellow old guy but if you meet him, you can tell he's still got a lot of vitality and there's certainly a sparkle in his eyes.
There's no doubt that these dogs with the biggest smiles are a dying breed in Ontario. I see less and less of them every year. Shame.
