I own a puppymill puppy that I bought from a pet store because I was uneducated. It is SO hard to watch my little pug dug suffer from genetic disorders. It bothers me more to see her suffer than to have to pay the pricey vet bills. I worry that soon my vet is going to say it's time to euthanize her, and she is only age 7.
Maybe this is why some of the posters were so passionate about what they had to say. They may be speaking from experience.
