Responsible breeders will do all they can to avoid these problems by researching pedigree and screening parents for certain inherited problems before breeding.
Keep this checklist and consider the following when choosing a breeder:
Where did you find out about this breeder? Responsible breeders have a wait list of puppy buyers. They usually don't find it necessary to advertise in newspapers or with a sign out in the front yard.
Do both parents (the sire and dam) have a hip clearance from the OFA (Orthopedic Foundation for Animals), PennHip? Ask to see the certificates. "My vet okayed the x-ray" is not a valid clearance.
Do both parents have current eye clearances from an Opthamologist or CERF certificate (Canine Eye Registry)? Ask to see the certificates.
Do either parent have other clearances, elbows, heart, EIC (exercise induced collapse) CNM (centronuclear myopathy) PRA, PRArcd, HNPK and thyroid? These are some of the other problems labradors can have and some breeders are checking for.
Are both parents at least 2 years old? Final hip clearances cannot be obtained before that age.
Do all four grandparents, siblings of the parents and any other puppies that they may have produced have these clearances? A responsible breeder will keep track of these statistics and honestly discuss any problems that have occurred in the lines and what has been done to prevent them from reoccurring.
Is the breeder willing to provide you with references and email addresses of other people who have purchased puppies from them?
Will the puppy have a limited registration with a mandatory spay/neuter contract? A breeder who cares enough about the breed to insist on these is likely to be a responsible breeder.
On what basis was the sire chosen? If the answer is "because he lives right down the street" or "because he is really good looking", sufficient thought was not put into the breeding.
Will the breeder be available to answer any question you might have for the life of the dog? Is this someone you would feel comfortable?
Is the breeder knowledgeable about the breed? Is he or she involved in competition with their dogs (field, obedience, or conformation)?
Are there a majority of titled dogs (the initials: CH, OTCH, CD, JH, WC... before or after the names) in the first two generations? The term champion lines means nothing if those titles are back three or more generations or there is only one or two in the whole pedigree.
Are the puppy's sire and dam available for you to meet? If the sire is unavailable can you email his owners or people who have his puppies to ask about temperament or health clearances? You should also be provided with pictures or videos.
Have the puppies been raised in the home - not in a kennel, barn or the back yard?
Is the breeder knowledgeable about raising puppies, critical neonatal periods, proper socialization techniques? Puppies that are raised without high exposure to gentle handling, human contact and a wide variety of noises and experiences OR are removed from their dam or litter mates before at least 7 weeks, may exhibit a wide variety of behavioral problems!
Does the breeder provide you with a 3-5 generation pedigree, copies of all clearances, health records and material to help you with feeding, training and housebreaking?
Have the puppies temperaments been evaluated and can the breeder guide you to the puppy that will best suit your lifestyle? A very shy puppy will not do well in a noisy household with small children, just as a very dominant puppy won't flourish in a sedate, senior citizen household. A caring breeder will know the puppies and be able to show you how to test them so that good matches can be made.
Do the puppies seem healthy, with no discharge from eyes or nose, no loose stools, no foul smelling ears? Are their coats soft, full and clean? Do they have plenty of energy when awake yet calm down easily when gently stroked?
Do the puppies have their first shots and have they been de-wormed & vet checked by the time they go to your home?
Does the breeder have only 1 or at most 2 breeds of dogs? If there are many breeds of dogs there, the chances are, the breeder cannot devote the time it takes to become knowledgeable about the breed.
Does the breeder belong to A Labrador Retriever Club and/or a local All-Breed Club.
Do you feel comfortable with this person, after all you are entering into a decade long relationship? Are you feeling intimidated or pressured? If so, keep looking!
Take full responsibility for this dog and all its needs for the next 10-15 years? This is NOT a task that can be left to children.
Invest the considerable time, money and patience it takes to train the dog to be a good companion? (This does not happen by itself!)
Always keep the dog safe; no running loose, riding in the back of an open pick up truck or being chained outside?
Make sure the dog gets enough attention and exercise? (Labrador puppies need several hours of both, every day!)
Live with shedding, retrieving, drooling and high activity for the next 10-15 years.
Spend the money it takes to provide proper veterinary care including but certainly not limited to: vaccines, heartworm testing and preventative, spaying or neutering and annual check ups? Be sure to consider the purchase of Pet Insurance for coverage in case of an accident, injury, or health problem.
Become educated about the proper care of the breed, correct training methods and how to groom? (There are many good books available, invest the time to read a few.)
Keep the breeder informed and up to date on the dogs accomplishments and problems?
Take your questions to the breeder or other appropriate professional before they become problems that are out of hand?
Have the patience to accept (and enjoy) the trials of Labrador puppyhood, which can last for three years, and each stage afterward?
Continue to accept responsibility for the dog despite inevitable life changes such as new babies, kids going off to school, moving or returning to work?
Resist impulse buying, and instead have the patience to make a responsible choice?
If you answered yes to ALL of the above you are ready to start contacting breeders. Start early because most responsible breeders have a waiting list ranging from a few months to a couple of years. Remember, the right puppy or adult dog IS worth waiting for!!
