"Where's my biscuit?"

This is our friend...'Marbles' the labrador who lives a couple of doors down from us....
he arrives everyday without fail at my front door 'begging for his biscuit!!
And he never arrives without a 'present' for me, an old bone of his, a twig or an apple butt......
He is huge, one of the biggest labradors we've ever seen, but he is a gentle giant....
he has a very scary bark tho' and he guards our cul-de-sac all day while his humans are away.....
