The Buster Food Cube is for playing & feeding. For dogs from 10kg & up. Feed your dog in a fun & entertaining way, give your dog a good & enjoyable experience & give your dog a happy & active life. If your dog is normally fed with dry food, the cube can be used for feeding. It is a good idea to fill the Buster Cube with a normal portion of food for your dog. Let your dog 'play' the food out of the cube & thereby use their natural instinct. If your dog is normally fed canned food, the Buster Cube can be used for playing & treats during the day. If you use Buster Cube for treats, please remember to reduce their total daily ration in order to avoid overweight.
