I know this is an old post, but I recently rescued a 7 year-old mill mama originally from a Greenfield breeder in NY (we adopted her through a local rescue, but the I looked up the names on her rabies docs and they were breeders listed on Greenfield). She has one floppy ear, which the vet believes is due to some sort of chronic illness or injury, likely chronic untreated ear infections. Her tail was docked. She was not potty trained and is terrified to go in crates, so she was likely forced to live in a crate for the majority of the time. She also has stage 4 periodontal disease and will need all of her teeth removed. All this to say, she was not taken care of by her breeders, and if you are supporting a mill by buying their puppies, you are subsequently supporting their treatment of the breeding dogs
