Kacee is an only doggie and she's going to remain an only doggie. She goes everywhere with me, including work and shopping. I could not take two. That would probably never work. She is calm and behaves at work (most of the time).
She loves to go. If there were two doggies, then she couldn't go all of the time. If I took her, then the other one would have a broken heart. I don't want to rock the boat. She has a full schedule of working, walking, and playing, so I don't believe there is much that she misses. She is well-trained. She rings the bell to go potty. She never messes in the house. She doesn't bark, but on occasion. Even then, it is not a lot of barking.
