Based on published listings, not hands-on testing.
Why consider it
Carhartt Training Harness is worth keeping separate for shoppers comparing that named model with the Nylon Duck No Pull version. We would inspect the control layout rather than assume the two names describe one item.
What could make us pass
Some cached Training listings are discontinued. Confirm the current item code and do not merge Nylon Duck stock into this model to imply availability.
Fit and care
Check the actual neck and chest ranges, entry method, leash point and care instructions. Watch the dog walk and turn in a secure space to assess shifting and front-leg clearance. Size names are not standardized across brands.
