1.  First and foremost, you will not find a reputable breeder in the
    newspaper.

    2.  How long have they been breeding and how often do they have
    a litter available? More than 2-3 litters per year is too much.

    3.  How many breeds do they breed? (more than one is a red flag)

    4.  How many dogs do they own or co-own?

    5.  Are they members of a Pug dog club?

    6.  Are they involved in some degree in rescue?

    7.  Are all their breeding pugs registered?

    8.  Do they show their pugs? (not a requirement, but if they don't,
    ask question #9).

    9.  Are they familiar with the Pug dog standard? (Study the
    standard and know what a nice quality Pug should look like...
    more on that below). Click this link to see the pug standard

    10.  Has any Pug in their breeding program produced puppies
    with a hereditary flaw? This is a big one and if you find a breeder
    in the aforementioned area and they say they have not, ask for
    proof in their breeding pug's genealogy at least 3 generations
    back.

    11.  Have their Pugs been screened for genetic defects? (i.e.;
    luxating patellas, elongated palettes, hips and eyes. Remember
    that even if they test for these things, like eyes for example... you
    can test for eye problems at 2 years old and 6 months later a
    problem can crop up...but the important thing is if it does that
    they DON'T breed that dog anymore!).

    12.  What kind of health guarantee do they offer? (Minimum of 1
    year is good. Walk away if it's only 48 or 72 hours!!) If they are
    confident in their bloodlines health they will at least offer you a
    year genetic health guarantee. Make sure their name and
    signature is on this document.

    13.  Do they require a spay/neuter contract on "pet" puppies? (A
    reputable breeder will require this, so if they don't care if you
    breed your "pet" quality pup down the road...walk away).

    14.  Will they be available to answer questions you may have any
    time during the dog's lifetime?

    15.  If a situation arises in where you can no longer keep the dog,
    i.e.; a move, health reasons, etc... Will they take the dog back?
    (reputable breeders will require this as part of their contract.)

    16.  Do they have the parents on the premises and encourage you
    to visit with them?

    17.  Lastly, a reputable breeder will interview YOU as well. They
    will ask you about your living situation (house vs. apartment),
    work schedule, and family members. They care where their pug
    puppies are going to live and most of the above information will
    freely be given to you - sometimes before you even ask.
