Our dog Sadie is the most amazing dog. She came from a shelter and was very sick as a pup with Kennel cough and a very serious lung disease but overcame them all. We are unsure of her breed we have heard different suggestions but tend to stick with the half lab half shepard. She is a VERY smart dog and teaching her to say "I love you" took only short time. Because of our love for her we would always tell her "I love you" and I could tell one day that when I said that she wanted to say something back so I kept saying "Sadie I love you" and then she barked 3 times - my eyes filled up with tears cause I know she really does love us.
