As you probably know, Andrew Cotter is the Scottish sports announcer whose videos of Olive and Mabel have become so popular. He also writes dog columns. I liked this one very much. (We have bought puppies from breeders and we have adopted rescues. As you'll see, he's familiar with both, too. So he is not preachy about it.) I am not SURE the link will work but I hope it does.
