Its fairly easy. Zac is the oldest and the others are a year or 2 younger then the next. I found it easier introducing puppies because the older dogs helped teach them. I have 4 acres so they get to enjoy running and get lots of exercise. I also take them to the lake and other dog friendly places to keep them exposed to different things. But its really fun having them all. Our Delivery people even enjoy saying hi to them when they drop packages off because they are so well behaved. I mean I wouldn't suggest everyone to get a large pack unless they know how to handle multiple dogs, but if people can manage and the dogs are happy its a good experience.
