Shop Service dog equipmentI know how difficult it is to find equipment that really works. I started designing service dog equipment because there was a serious lack of good quality, user-friendly gear out there. There was a gap between what people needed and what was available. Every day I strive to help people find solutions that will make their lives better. – Katrina Boldry, Owner & Designer
