I played RELEASE to my 9 dogs – 4 Great Danes, 2 Setters, 2 Fox Terriers and one retriever. I have found a great difference in them all. One Great Dane and one Fox Terrier always had an edgy relationship. They are now the best of friends, and the Great Dane is a lot more relaxed as a whole. I can’t wait to play this audio with all the other dogs in our family. Thank you very much and keep up the good work.
