NORTHMATE ® GREEN is a specially designed food bowl shaped like a tuft of grass that turns your dog's meal into a challenging game. The food is distributed in the NORTHMATE ® GREEN and it is your dog's job to take the food out between the many blades of grass. NORTHMATE ® GREEN prolongs the meal considerably - it makes it difficult for the dog to gobble down its food and reduces the risk of flatulence. The result is a happier and healthier dog. NORTH MATE ® GREEN is designed for all dogs, regardless of breed or weight. It can absorb both dry and wet food. NORTHMATE ® GREEN is made of hard plastic (without phthalic acid ester) and can therefore be used outdoors and cleaned in the dishwasher.
