What could make us pass
We would not treat Ultra Tough as an escape-test finding. Choose it only when the documented differences justify the cost for a dog that tolerates crating.
Documented features
Fit before features
Confirm usable interior dimensions and room to stand, turn and rest comfortably. Size names and exterior measurements do not establish fit. Check the manufacturer’s instructions for the selected variant.
Size evidence still needed
This model remains available for research. We do not substitute outside or nominal dimensions for usable inside space, so it is not in measured-size recommendations.
