I personally would not. If you are wanting a puppy sooner rather than later, I'd just start looking at local shelters, around here there are always plenty of puppies available. If you are definitely wanting a lab, I'd either contact a lab rescue or start researching breeders. With the understanding that you likely would need to wait if you decide to go the reputable breeder route. Nothing wrong with not wanting to wait, but I would not go this current route, I'd rather get a puppy that is in rescue or at a shelter and has likely been kept with his littermates for at least eight weeks as well as having some sort of vetting already done.
