Dogs can be housed in the Caesars PetStay Casino program in rooms with proper harnesses and training, weighing up to 50 pounds each. With the opening of Caesar’s Palace’s new pet-friendly casino, Las Vegas has become even more animal-friendly. It is advisable to call ahead to the casino of your choice to inquire about their policies regarding dogs. Some casinos allow dogs in specific areas only, while others may not allow them on the premises at all. There is no definitive answer to this question as policies on dogs in Tahoe casinos vary from establishment to establishment.
