We love that you've become a big rottie snugglepup, instead of the growly aloof dog you were considering as a puplet.
However -- I must point out that you area large black dog, and we tend to have a house kept as dark as possible in summer so it stays cool. This means that when you stretch out on the lounge, the Humans might not realise you're there, especially if we think you're still laying in the cool of the bathroom.
One of these days, you're going to get sat on my lad, and that could be embarrassing for all concerned. We might need to fit you with a little locator light.
