Completely open. I do not have a fenced yard however there is multiple areas near me where dogs play. I take my own two there all the time. I have two English Bulldogs, (neither are fixed), however my boy JoJo does NOT display any aggressive or dominant behaviors. He and Roxy will be the best friends to any animal coming into our home. They are lovable playful and energetic and will make sure whomever enters is welcomed and safe. They are closer than ever, make up my entire world, and if your pet is with us, they surely will have the time of their life. We go on walks daly-weekly depending on the weather of course. And Play daily. Sometimes we can play softly, or they play together. JoJo is a muscular Bulldog who loves to tumble so when I play with him i wrestle and even if he forgets his own strength he knows how to play gently to others. The two are my best friends, and more than companions. Your pet will be in safe; good; and caring hands with three of us looking after them.
