Many dogs eat from the same height throughout their lives, even though their bodies change. This set was designed to put your tray higher and allowing pets of all ages to eat comfortably and ergonomically. Eating at the right height reduces pressure on joints, aids digestion, and limits air swallowing, which is especially important for older dogs or animals with osteoarthritis. The height can be easily adjusted without tools, thanks to a clever mechanism. The result is a product that grows with your pet and remains relevant for years to come. -> Please note: This set has to be used in combination with a medium or large Pino tray.
