These silicone target mats are perfect for helping dogs have even front, or rear foot placement and weighting. The smooth silicone bottom sticks nicely to most surfaces, and the textured top surface gives dogs proprioceptove feedback when their feet are on the surface. 
These are also excellent to place under other equipment that slips to help reduce unwanted movement. 
Textures on the surface may vary. Price is per silicone mat, but it is reccomended that you buy two. Best efforts will be made to provide pairs in the same colour.
