These harnesses are made of a deep red velvet, bright sparkly Czech crystals, red satin ribbon, and are lined in red satin. The exclusive side straps keep the harness from riding under the belly. This reduces strain on the neck and chafing under the belly. The XSmall, Small , and Medium are embellished with 20 vibrant crystals, the Large and XLarge use 26 crystals to adorn the heart. Please Note: You must order a minimum of 4 harnesses at a time, you may mix and match sizes.
