The puppies from these puppy mills are called "purebreds" but often assume little similarity to their breed standard. Decisions about which male to use with which female are based on profitability, leaving genetic issues for the unsuspecting puppy buyers to worry about later.

Unsafe breeding practices incline puppy mill dogs to inherited disorders like immune system deficiency, hip dysplasia, demodectic mange, seizures, yeast infections, or aggressive dog behavior.

You will experience housetraining problems because the puppy has been confined too close to feces and urine. This causes damage to the puppy's natural instincts to keep the den area clean.

Puppy mills over breed indiscriminately, as often as they can with as little cash output as possible. Puppy mills owners do not care about the future health of the puppies or the ruin they will cause in the lives of the people who buy them.

Furthermore, registration papers do not guarantee proper breeding conditions, health, quality, or claims to lineage of the puppy.
The Indonesian Kennel Club registers thousands of puppies from puppy mills each year without questioning the horrendous conditions in which these puppies are raised.

It is seldom profitable to breed dogs humanely and responsibly!
