Considerations In Puppy Parenthood

Mike came to me today and declared he wanted a Rottweiler puppy. My reply to him was Are you prepared to invest a lot of time, money and energy into raising this thing? He in return kind of blinked at me with that blank what the hell are you talking about look?
Puppies of any breed require a ton of time, energy, and attention in order to ensure they become welladjusted members of the family.
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 Rottweiler 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.
