Right out of the blue, my Aunt got a dog. He is a Papillion named Charlie. My Aunt and my two cousins came over for the holiday yesterday and brought the new addition. My dog, Copper, a 10-year old miniature longhaired dachshund seemed unphased. Charlie can’t talk yet; he is only three months old. Do all dogs need to learn how to speak? Heidi, my previous miniature shorthaired dachshund didn’t discover that she could bark until she was almost a year old.
