It's amazing how much care Schulz put into Peanuts' backgrounds in the old days. Look at all the different kinds of tree, the houses, the snow and the path. Patty has a couple of very nice poses in this one too, especially with her shovel. Charlie Brown running up to see her in panel 4 is also very good; panel 4 overall is one of the most beautiful of the whole strip's run. The characters, despite their stylistic deformations, are realized in three dimensions very well.
Of course dogs will eat just about anything, but is it weird that Snoopy likes carrots so much that he'd swipe one off a snowman?
