Snow in south Texas

We rarely get snow here in south Texas, but it started about 9:00 PM CST last night. Our dog is 18-20 months old and has never seen snow. Late last night I took him out for his late night potty stop before bedtime. He wanted no part of it, he stepped off the patio, stuck his nose in it and went back to the door to go back inside. This morning we have about 3-4" on the ground and the dog stepped off, relieved himself and bolted back to the door. He looks at us while outside with the "WTF" look on his face. LMAO
