MADE FOR LARGE DOGS: Unlike other water bottles marketed for dogs, the Lixit top fill water bottle is made using an extra large tube to meet the watering needs of large pets . The tube is made from 304 American stainless steel that is commonly found in food preparation. We finish our tubes till they have a satin finish like quality silverware. | FILL FROM THE TOP: The Lixit top fill dog bottle features a lid on the top that allows you to fill the bottle without removing it from the cage. | NO DRIP VALVE: This bottle features Lixit’s Patented no drip valve. This valve is completely serviceable and can easily be rebuilt if it starts to leak. | DUAL MOUNT: The Lixit top fill bottle is flat on both sides and can be mounted outside or inside the cage. The 44oz bottle features a large open ended clamp to easily remove the bottle from the cage. | Lixit Top Fill water bottles are proudly assembled in the USA
