Max Crating Time by Age

A common question for those first crate training a puppy is, “How long can I keep him in his crate?”.
Provided that you have been introducing the crate properly, your puppy can usually remain in the crate without a potty break for the following lengths of time.
Keep in mind that every dog is an individual and may differ from the average. Also remember that puppies under 6 months have weak bladder control.

4 months 1 hour
5 months 2 hours
6 months 3-4 hours
1 year 5+ hours
Greater than 1 year 9 hours
