These saddlebags are all made in prime leather and they are fully customizable. They have an adjustable leather strap with a quick release buckle to be fixed on the dog's belly and two hook and loop straps to be fixed on the harness. Straps fasten onto themselves with industrial strength hook and loop. Straps are set approximately 6" apart but do have some wiggle room. The two bags measure 6" X 6.5" and are fixed on the cape to give the dog an extra comfort while wearing them. The total measure of the cape is 19" X 6.5" plus the belly strap that can be adjusted from 23" to 48" (from M to XXL harness size). Both cape and bags have 2 hook and loop straps for attaching your patches and you can choose if you also want an ID card holder or not. We can customize the cape for any specific needs of service dogs.
