I agree with Nexu he should be able to hold it for at least 3 hours.... I crated my boxer/lab (still do when I go to work) they do not like to potty in their den.. He holds it all day when I am gone. Good luckNexu\";p=\"84199 said:Crating helps them control their bodily functions as they typically do not want to soil their "den". They are clean dogs and crating helps teach them to hold it. I would think, at a minimum, your dog should be able to go 3-4 hours without going potty
