Safe breeding practices - Puppy Mills

My wife and I have been thinking about getting a puppy and making it part of our family since our kids are grown up and out of the house and all of the animals went with them when they left.  I had talked to my brother in-law about it and he told me to make sure it a safe breeder puppy, which I wasn’t completely clear on how to do what he was talking about, but when I asked him, he told me to go onto the Internet and to google the words puppy mills and read up on the subject. So I did and I found that you can learn so much about what you can look for, and what kind of things you should find out before you go to the store and see a cute puppy, purchase it and walk out. You can save hundreds, maybe even thousands of dollars just by taking the time to do a bit of research, and of course with the Internet it can’t get much easier than that.
