I recently adopted a shiba inu from my local animal shelter. She is the first shiba that I have ever owned. I also have a chow chow and a golden retriever who are best friends. My shiba doesn't realy care for the other two dogs and she just plays with her toys by herself. How do I get her to interact with the two dogs a little more? She is 2 years old as to the other two who are 4 years old.
