Cute dogs! (in one case, very big cute dog!)
I'd love a dog, but since I'm at work all day, it's not fair on a dog to leave it alone for that long. I'm too far away to go home at lunchtime, and to be honest, even leaving a dog by itself all morning and afternoon, with a brief walkies at lunchtime doesn't seem fair five days a week.
At least an adult cat can amuse itself (ie sleep!) all day.
Still, keep the dog piccies coming, so I can vicariously enjoy all your dogs!
