Private rescues spend a lot of time evaluating resource guarding, cat-safeness, friendliness with other dogs, children-safeness, trainability, exercise level, and overall temperament. Private rescues who foster their dogs gain a very intimate relationship with the dog. As an adult, the dog's temperament is stable and solid. A puppy's temperament fluctuates. IMO, you get a potty-trained dog with a solid temperament who desperately needs a home. Adopt

People with long work schedules can certainly own dogs, but people with such schedules should probably think twice about puppies.
