Considerations In Puppy Parenthood

Mike declared at breakfast today that he intended to get a Labrador 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 require a ton of time and energy to be invested in them in order to ensure they end up being well behaved and well adjusted members of the family.
Puppies also take a ton of extra money beyond their purchase price. Things like health care, room and board and all the incidentals add up really fast.
I am not against having a Labrador 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.
