Well, mine's 4 years old now, weighs about the same as yours. Goes up and down a few kilos every now and then. Harlequins are nice. I originally went for a yellow one, but they were "sold out". His mom is yellow, his father is striped like Mo, only a lot darker. He came out striped, with the brown bits somewhere in between his mom and dad. His brothers and sisters are a mix of all three, a few like him, a few like moms, a few like dad.
Guy around the corner has a 2 years old black bitch. You should see the two of them play together. It's like a little scale re-enactment of Hiroshima.
I love dogs.
