Does your dog or cat talk to you ?

My English Mastiff is the only dog that will talk to me. There are times where I question if he is trying to have a full on conversation with me. Ever since he was a puppy he has always opened his mouth and mimicked random things we would say. We used to yell "I love you" to him as a puppy, which made him howl back at us. It was the cutest thing in the world and still is. I think dogs are aware of what we're doing and at times might just want to entertain us. I believe they know that nothing will come out of their mouths and make sense, but they'll try anyway.
