Additionally, some casinos may offer pet-friendly hotel rooms, so it is best to inquire with the casino before bringing your four-legged friend. However, there are some casinos in Oklahoma that allow service animals, as long as they are certified and in proper control of their handlers. This is due to the potential for health and safety hazards, as well as the fact that the gaming environment is meant to be a haven for adults and a distraction-free zone. It is important to note that dogs are not allowed in Oklahoma casinos.
