2021 humane statement remains current, no trainer-organization endorsement
Read the source ↗Why no ignore-crying rule?
VCA, RSPCA and Wisconsin Humane Society include passages about brief vocalization or waiting for a gap in noise. PDSA advises stepping back when worry appears. Cornell says distressed dogs should never be forced to remain crated alone. A website cannot reliably sort those situations for an individual animal, so we do not prescribe waiting for silence or a cry-it-out interval.
Why no hours calculator?
Sources offer different duration examples and qualifications. Those are not measurements of an individual dog's comfort, bladder capacity or ability to cope alone. We do not average them or use the longest as permission to wait.
What is not being recommended?
No specific crate, toy, chew, cover, supplement or transport approval is endorsed. A source's product examples do not establish suitability for every dog. Household crate learning and veterinary recovery restrictions are different decisions.
