The large skid stop basic bowl is an everyday plastic bowl for medium/large pets. The skid stop bowls were designed with a rubbery base to prevent the bowl from sliding or moving around on the floor while the pet is eating. The rubber bottom creates a firm grip on slippery surfaces to prevent the bowl from moving or tipping, this also helps to prevents spills. Skid stop bowls are dishwasher safe. Available in assorted colors.
