Final answer:
Commercial breeders are shifting their sales strategies by now taking puppies directly to auctions to sell to rescues, indicative of a change in market dynamics. This approach is possibly influenced by increased awareness of puppy mills but fundamentally represents a change in how breeders choose to sell their animals.
Step-by-step explanation:
A Shift in Breeder Sales Strategies
Given the scenario where commercial breeders are now taking their puppies directly to the auction to sell to rescues instead of reserving them for pet stores, the most appropriate choice is C) A shift in breeder sales strategies.
This shift is not principally a reflection of the conditions in pet stores improving (D), nor does it necessarily point to a decreased demand for puppies (A). The decision by breeders to sell directly to rescues at auctions could indeed be partially influenced by increased awareness of puppy mills (B), but the primary subject of the question is a change in how breeders are choosing to market and sell their animals.
Importance of Avoiding Inbreeding in Domestic Animal Breeding
Avoiding inbreeding in the breeding of domesticated animals is a good practice because it helps maintain genetic diversity, which is critical for the health and wellbeing of the animals.
Inbreeding can amplify the risk for hereditary health issues, like cancer, hip dysplasia, and deafness. Responsible breeders attempt to maximize genetic diversity to promote overall health and minimize the prevalence of genetic disorders.
