Create a realistic photo of a sad Basset Hound puppy with long ears sitting on a large cozy armchair. The puppy is wearing a bright Christmas sweater, which emphasizes the festive atmosphere. In the background, you can see a fireplace with a slight flutter of fire, creating a warm light. Next to the armchair is a small table with a plate of biscuits and a cup of tea, adding charm to a winter evening. The whole scene should convey a sense of home comfort and tenderness, emphasizing the atmosphere of celebration and caring for your beloved pet
