Tre Ponti Liberta, Size 2.5, red. I received this as a gift and tried it on, but the size didn't fit. No tags. Adjustable strap model for easy size adjustment. This dog harness features an innovative attachment and size adjustment system using straps (cords) with cord locks. ◆ You can easily adjust the gap between the harness and the body from "snug" to "loose" simply by tightening or loosening the straps with the cord lock.
