To dream of a dog kennel represents protective behavior that is being kept under control or forced to wait.
A kennel may also represent controlling other people because there are concerns that people will go overboard if left to their own devices. Using someone or something protective only when it suits your purposes.
Positively, may reflect dangerous or aggressive reactions being controlled until it’s appropriate. Fighting or revenge that is not safe for the present moment.
Negatively, may reflect feelings that it’s terrible that nobody is being allowed to “kick ass” or defend themselves. Unreasonable amounts of control or management over other people’s behavior. Feeling the need for total control over others for merely suspecting that they might get out of control.
