The first photo is Casper leaning forward looking for a treat. The second is Casper in one of the mats with bumpers.
You may notice that Casper has lost a lot of weight. Two years ago he was a portly 10 pounds (4.3 kg), now he is a thin 5 pounds (2.3 kg). Since he is now underweight, he gets as many treats as he wants. I'd like to see him at 6 pounds (2.7 kg) which would be a better weight for him.
