More: The smartest dog I have ever owned!! We have to be very careful what words we use around her. Ball, treat, walk, and Koi are just a few. She also knows what time it is! She reminds us when it's 5pm if we forget to feed the Koi in our pond. She calls the Koi for dinner by barking and stops as soon as we finish. We call our home Talking Dog Farm because she is so vocal and "talks" to us all the time!!
