Medium Dogs 20 to 50 lbs

Medium-sized dog harnesses for medium dogs (20 to 50 lbs.). In addition to our medium harness, we have a number of leashes, toys, and treats for mid-sized dogs. 

How to Measure your dog

#1 Front Measurement from the chest bone just below the throat to even with Mid Back.

#2 Girth Measurement = Circumference of the waist at Mid Back.

Measuring Tip - Use your dogs leash to measure and compare it to a measuring tape.  Your dog will be more comfortable with something that he's used to. Use our harness measuring and fitting guide if you need help taking measurements.
