Simple Dog Harnesses for Small Dogs – Our Gooby Simple Step-In Harness III is made for small breed dogs. This means that our largest size will most likely fit a small dog up to 35 lbs. In order to fully utilize the functionality of the harness, as well as the fit, we recommend measuring the largest part of the dog’s chest and following the recommended sizes below. If the measurement is between sizes, please size up.
Sizing Adjustment Tab – Used to adjust the firmness around the chest such that even when the leash is off, the harness stays intact. [Chest Sizing – Small 14.25∼17″, Medium 16.75∼21.5″, Large 18.5∼23.75″ – Please measure the largest part of the dog’s chest]
Breathable Inner Mesh & Scratch Resistant Outer Layer – Scratch resistant outer layer protects the no pull harness from paw scratching. Inner mesh inner layer keeps your dog cool and comfortable.
Quick Release Buckle – Easy On, Easy Off Simple Step In Dog Harness is very easy to put and easy to adjust, perfect for a dog run or easy walk indoor or outdoor. In house custom designed buckle for easy release and puts less stress on your fingers.
POM Plastic Leash Ring – The same material used in seat belt buckles. Both lightweight and extremely durable.
