Any introduction should be done gradually and on "neutral" ground. You can use a pheromone product such as an Adaptil collar to decrease anxiety or aggression. Introductions should start with Max being able to hear and smell a new dog but not see him. This can be done a friend's house or perhaps a family member's home. Again, some place neutral to both dogs. Once he is acclimated, he should be able to see the new dog but have no physical contact. This can be done using the fence at a dog park. Eventually, you will be able to physically introduce Max to the dog. Use a leash on both dogs for safety and muzzles if necessary. Go slowly, don't force him but correct any negative or aggressive behaviors immediately. Praise and reward him as he progresses.

    Keep them completely separate, then begin again introducing them gradually. Start by having a closed door between them. Allow them to hear and smell one another but not see each other. Do this for gradually increasing periods of time. The next step would be to allow them to see one another from a distance. You can slowly decrease the distance while increasing the time. Move on to having them in the same room, but with one in a closed kennel. Eventually, you can try a physical introduction. Keep them both on leashes (and muzzled if necessary) for safety. Correct any negative behaviors immediately and praise/reward both as they progress. A pheromone product, such as the Adaptil collar or DAP plug in diffuser, may help to decrease any anxiety or aggression. Be sure to provide extra toys, bowls and beds to prevent resource protection.
