Owners of new puppies and any adult dogs with destruction and/or housebreaking problems should crate train. The only time crate training would not be advisable is in a situation where a puppy will be left alone for an extended period of time and a family member cannot come home to let the puppy out during the day. It is a dog’s natural instinct to keep his crate/home clean, so he will “hold it” as long as he can before eliminating in the crate. The maximum time an 8 week old puppy should be in his crate without a break is 4 hours. Puppies younger than 8 weeks have to “go” about every 2-3 hours so they should be given a crate-break at those intervals. Except for overnight sleeping, crate confinement approaching 8 hours is strongly discouraged. As the puppy gets older (4-6 months) you can gradually leave him in his crate for longer periods of time, but you should never exceed 8 hours for any dog.
If a family member is unable to come home midday to let the puppy out, there a couple alternatives. The most desirable would be for a pet-sitter, relative, or neighbor to come by the house and let the puppy out while he is young. If this is not an option, leave the puppy in a confined area with his crate with the crate door open. This way he can sleep in the crate and come out of his crate to use the bathroom. A collapsible wire barrier called an “exercise pen” (or X-pen) can be used to create a damage proof, safe inside area or a small bathroom can be used. However, using this type of set-up will lengthen the housebreaking process because the puppy will be learning to eliminate in the house. Also, some puppies can quickly learn to climb out of the X-pen.
