When Staci called, she was looking for an intelligent mastiff that she might show. Not a problem. Keena has always been a smart girl and it was apparent early. Keena was easily trained and has earned her therapy dog certificate. Keena did have a rough spot and had to be spayed because she developed pyometra. Staci did all of us a favor and wrote about their ordeal (Keena's Story). Keena is a beautiful, elegant mastiff.
