If you want a puppy, be sure you have the time and patience to deal with housebreaking, crying at night, chewed furniture and other damage a puppy can cause daily, for months. Another point about puppies is, you never know how a puppy will look when it grows up, or its general personality until that dog reaches around 18-24 months old. And don't forget the puppy energy level. If you open your heart to an adult dog, you can see the dog's general personality, and you can also see a mature version of him. Most adult dogs are very adaptable and most will adjust well to your home.
Adult dogs can and do bond to new owners quite readily.
In fact, most Dogs want to bond to an owner strongly, and are very willing to do so. You still need to provide structure, love, and training for an adult dog, as you would for any dog you raise, but the puppy hood chores are over for the most part with most Rescue and adult dogs. Between 96 and 2000 we had a very active message board for support of those that cared for the breed and needed a place to gather not only to exchange ideas but also to get help with many of the problems that rescue dogs often fall victum to.
