The dark spots on the land are not signs of unattended dogs- they're leaves which weren't ready to fall when the raking humans thought they should. Snowfall is not usually peppered with leaves, which I interpret as another sign of this garden's reluctance to let go.
The rose garden may not seem ready for dormancy, but the Chihuahua sure is looking a bit drowsy. All that shivering uses up a lot of energy, as does walking on 3 legs to protect the 4th from that nasty cold wet stuff.
The warmer temperature today creates the effect of a spring thaw- last night's snowman has already bit the dust. The garden appears to be getting its way.
