Considerations In Puppy Parenthood

Mike declared at breakfast today that he intended to get a Golden Retriever puppy. I just kind of looked at him and asked Are you prepared to invest a lot of time, money, and energy into raising this puppy? Mike just kind of looked at me with that what the hell are you talking about look.
Puppies are attention hogs. They practically insist on having hours upon hours of undivided attention and supervision as well as the energy to keep up with them before you can count on them behaving appropriately as adult dogs.
They also take a ton of money when you figure their health care, their room and board, and all the incidentals you can never plan for.
I am not against having a Golden Retriever dog, I just want to be sure we aren't making a decision like adding a pet to our family just on impulse. This is a huge commitment and we should weigh the decision carefully.
