Since you're introducing two puppies, you will have different challanges than if you were introducing two adults.

There are two red flags that stick out at me when someone says they have more than one puppy. The first is concerns about the puppies overbonding. This is especially a concern for littermates. If the puppies overbond, they may decide you're not interesting and won't listen to a word you say. To prevent this, do not allow the puppies to be together 24/7. Make sure they get plenty of time apart and also that you spend individual time with each of them.

The second concern is rivalry. Since they are so close in age, it would be best if there is a considerable size and gender difference. The least they have in common (size, age, gender), the greater chance of a peaceful household you'll have.

I'd recommend taking each one through a Puppy Kindegarten class to ensure you build a bond with the new puppy and strengthen your bond with Bandit.
