Please consider the following:
If you want a dog of a certain personality adopt an older teenager or an adult. This way, what you see is what you get. This is the dog that will be part of your family for the next 10-15 years - not the little puppy that was so cute!
Likewise, it is impossible to predict what a puppy will physically grow into as an adult. Blue-eyed puppies grow into green-eyed adults. Small puppies grow into jumbo dogs or seemingly large puppies may turn out to be petite adults.
Puppies are very energetic and playful.
They do not understand the difference between batting around their jingle ball or eating your pearl earrings or batting your favorite vase off of the shelf. Puppies wrestle and play very aggressively, are easily stimulated and need constant attention. Puppies, especially when left alone, may destroy your furniture, your phone wires, your plants or your shoes. Adult dogs are calmer and are not as likely to destroy your furnishings or keep you awake at night.
By far, the most common victims of animal bites and scratches are children. Puppies are still learning how rough to play and what it means for humans to have no fur.
