We've tested our collar & leash products for strength & durability for everyday use. Our buckles are made with a high tensile strength and are run through a tensile test to ensure safety during normal use and everyday wear and tear. (Wear and tear associated with scratching, biting, and rubbing of decorative fabric excluded). Each consumer is responsible for determining the suitability of 3DD products for their individual situation and assumes all responsibility/liability by purchasing said product.
