NEW Double Non-Slip Design On the basis of the common bottom non-slip particle design, our dog sniffing mat also added three large suction cups to make it more stable while using. The three suction cups are very durable and large (size: 3.15x3.15 inches), don't worry about being swallowed by large dogs. Upgraded Durable Petal Design Our dog slow feeding mat is made of eco-friendly plush fabric and waterproof oxford-cloth. The plush fabric petal is different from others, it is more resistant to tearing which is the highlight improvement of this kind of product. Machine washable and dryer safe without deformation. Multi-useful Drawstring Design This anti-slip dog sniffing puzzle toy can be used as a sniffing training mat or slow feeding bowl with its convenient drawstring design. You can expand it to the largest size to use as a sniffing pad, or shrink it smaller to use as a feeding bowl. Large Size & Portable The largest unfolded diameter of our sniffing dog toy is 19.7 inches, fits all sizes of dogs and cats. Also, can be shrunk into a small storage bag to store or hang on when not in use. Portable for outdoor use. Slow Feeding Training & Consume Extra Energy Training the dog's natural foraging skill by looking for snacks or food hidden in this sniffing mat, not only can slow down their eating to prevent digestive problems, but also help to consume their extra energy. Using this treat feed mat for 10 minutes is equivalent to 1 hour of exercise, which will help to avoid our dog being bored and engaged in destructive behavior.
