This item was received from someone else. It is unused. As shown in the last picture, there is a dent of about 2-3 centimeters on the water bottle. There are no holes that would cause water leakage. Removable and easy to clean. Dog bowl stand: The water bottle has a large capacity, so you don't need to refill it frequently. The large capacity design allows you to store more water for a longer period. Automatic drinking bottle: The non-slip mat design on the bottom prevents the bottle from moving when drinking.
