Difficulty: Moderately Challenging
Step1
Rub your new pet with a towel before bringing him or her home. Then place the towel beneath your current dog’s food bowl. If she is familiar with the scent, she will less likely be reactive when he meets the new pet.
Step2
If you’re introducing a cat to your dog, provide the cat with a safe area to escape to. You might need to gate off that area.
Step3
Introduce the dogs on a leash in a neutral location. This way your current dog won’t view the new dog as an intruder. If you are introducing a cat, do not hold him in your arms. A frightened cat might scratch.
Step4
Pay close attention to the dog’s body language. If the dogs lower their front elbows to the ground and put their backsides in the air, that’s a sign they want to play. If they stiffen up, stare for a prolonged period, have raised hair, or growl, it’s probably time to end the encounter for the time being. Take them for a walk within sight of each other and use cheerful, positive tones.
Step5
Feed the dogs from separate bowls and watch to make sure they don’t get into each other’s bowls. That is a likely way for a fight to start. If you are introducing a dog to a cat, place the dog’s food bowl by the door to the cat’s room so the dog will make a positive association between food and the cat.
Step6
Make sure all of your old dog's toys are out of reach of the new dog to prevent fights.
Step7
Spend more time with your pets during the transition period (for at least a few weeks) and keep your old dog’s routine as close to normal as possible to reduce his stress level.
