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 get the food out between the many blades of grass. NORTHMATE ® GREEN lengthens the meal considerably - it makes it more difficult for the dog to swallow its food and reduces the risk of gas. The result is a happier, healthier dog. NORTH MATE ® GREEN is designed for all dogs, regardless of breed or weight. He can take in dry as well as moist feed. NORTHMATE ® GREEN is made of hard plastic (without phthalic acid ester) and can therefore be used outdoors and cleaned in the dishwasher.
