If you have an existing dog and are getting another adult, then it can be less stressful for all concerned to have them meet initially on a neutral ground. For instance, have a family member or a friend bring your dog to meet the new one on a walk (both on leads at first) to keep potential territorial argument to a minimum. Dogs that are different sexes are likely to cause less upset.

Before bringing the new dog home, remove anything he and your existing pet are likely to fight over – like toys and food bowls. Always be sure to pay attention to your existing pet first, so he doesn’t feel excluded. Avoid situations that may cause aggravation between the two; for instance, feed them separately at first, and don’t leave them alone together until it’s obvious they have become friends.

While a puppy usually settles in very quickly and adapts to your routine well, an adult dog often takes longer. He will feel displaced and unsettled for a while, and you should try to give him the time and space he needs to adjust during that period. Try to be sympathetic to how he feels, but don’t allow any bad habits to begin – like allowing him to climb on furniture or receive tidbits from the table – that you may later want to correct.
