Cryptodog is experimental software. It is suitable for educational and casual purposes only.
Do not use Cryptodog if you have a strong need for anonymity and privacy. This includes journalists, sources, activists, and citizens of oppressive countries.
Cryptodog is based on version 2.2.2 of Cryptocat. The vast majority of changes are UI-related; neither the client cryptography nor server backend have been modified. However, this does not preclude Cryptodog from introducing vulnerabilities not present in Cryptocat.
For further details regarding Cryptodog's security model, see the Cryptocat Wiki.
