A puppy mill is a large-scale commercial dog breeding operation that prioritizes profit over the well-being of the animals. In these facilities, dogs are often kept in overcrowded and unsanitary conditions, leading to health problems and poor living environments. The focus is on producing as many puppies as possible, often at the expense of the mothers, who may be bred repeatedly without proper care. Many puppies from puppy mills are sold through pet stores or online, which can contribute to the cycle of abuse. Adopting from shelters or reputable breeders is a better choice, as it helps combat the issues associated with puppy mills and promotes the welfare of dogs.
