😆 ok, then probably add some mental stimulation to the walk. Agility work out or sniffing use to work, but you know your dog better, whatever activity that calms him. That is your advantage here, you already know both animals so it will be easier to read their body language and act on that. I can’t assure you they will be friends, but if you can make then both feel safe, most times they can share the space without problems. It may take time and work, but it can be done. Best of luck!! 😊
