My other dog was a female German Shepherd/Pit mix who basically raised my Shiba Inu from when she was just a puppy. Now that my other dog has passed, my Shiba is by herself with the exception of a kitten. I take her to the dog park daily where she is starting to come out of her grieving but I have been considering getting another dog or puppy to keep her company when I am at work or not home, but I am not sure if I should or not. Being that she is 5 yrs old, she is still quite playful but from what I've read, Shibas are best introduced to other dog breeds when they are pups and I don't want to cause more trouble. But she seems so lonely and I would love to be able to get her another companion especially when there are so many dogs without homes and I'm a strong advocate for adopting dogs from shelters/pounds. She gets along with most of the dogs at the dog park, too. Any advice would be greatly appreciated. Thanks.
