The Busy Buddy Kibble Nibble toy keeps dogs engaged as they work for their food, which appeals to their natural hunting instincts. This interactive toy also prevents rapid eating to assist with weight management efforts. The toy holds an entire meal and is the perfect way to turn mealtime into playtime. To use, twist apart the Kibble Nibble. Load with kibble, and then twist the toy back together. If you would like kibble to come out faster, you can trim the Treat Meter prongs. Once the prongs are cut, there??s no going back, so we recommend trimming only a little at a time and then testing.
