【Smell Training】: Our snuff ball is made of many folded circles, which hide food and encourage your dog to sniff and find the source of food odors to train pet’s sense of smell.< /p> 【Improved】: The sniff ball is an upgraded version of the traditional dog search mat. When you use the sniffer ball for the first time, you can place the food on the edge of the ball where it is easy to find, thenput food inside the ball to make it a little harder. 【Slow Feeder】: By hiding snacks in the folds of the dog digging mat, instead of feeding food directly with your hands or in a bowl. Your pet needs time and energy to find each meal, which will distract yourpuppy and will slow down the rate of feeding. Dogs eat while playing, so your pet can develop good eating habits. 【Safe Material】: The main fabric of the snuffle ball is environmentally friendly polar fleece, which is soft and skin-friendly. This fabric is safe and non-toxic, and will not bring any discomfort or choking hazard to your pet,so
