Final answer:
The claim that rescues advertise the origins and purchase price of dogs from puppy mills is false. Rescues focus on rehabilitation and rehoming, not promoting the dog's past.
Step-by-step explanation:
The statement that rescues who buy their dogs from puppy mills always advertise exactly where their dogs came from and how much they paid for them is False. Rescues aim to save dogs from situations such as puppy mills, and their focus is on the rehabilitation and rehoming of these animals rather than on advertising their past or purchase price. Moreover, highlighting that a dog is from a puppy mill could inadvertently promote such places. Rescue organizations usually prioritize the health and well-being of the animals, providing necessary medical care, and preparing them for a future with a loving family.
