Research Driving Better Pet Health

As part of our commitment to advancing pet health care, we created a patented pet medical records software, PetWare®. This system collects data from every pet cared for in our hospitals. Our BARK team aggregates and analyzes data and shares findings, so everyone can stay on top of trends and needs in pet health care.
