• doghouse save will save your dashboard and monitors to json files in ~/.doghouse.
• doghouse sync will take your dashboards and monitors stored in ~/.doghouse and push them back to Datadog. This merely augments config in Datadog and is not destructive.
• doghouse list <object_type> will display a list of resources of a specified type. dashboard and monitor are both supported here.
• doghouse configure will reconfigure the Datadog credentials. Optionally accepts --api-key and --app-key as options to forgo user input.

Credentials are read from config.yml located in ~/.doghouse. This is in the form:

api_key: <api_key>
app_key: <app_key>

First usage of the CLI will ask for credentials if they don't already exist anyway.
