My dog was an accidental breeding of a very young male Shiba and a very small Beagle. I got her when she was 6 weeks and lost her when she was 16.5. We lived in apts with no yard and houses with fenced yards. When we lived in apts, we went to the dog park every day. I moved her around a lot and changed her environment several times. She went through 2 divorces and 2 cross country moves with me. She adapted to anything I threw at her. I never had a problem with her disliking people, kids, or other animals.
Believe me, she was not a walk in the park every day. She could never go anywhere without a leash. She was a bolter if she saw daylight. The first couple of years of her life she had to be crated if I wasn't in the house. I came home once when she was a puppy and she had destroyed a 10 pound bag of flour and a bag of potting soil. I learned that if you left something where she could get it, she would get it. If she destroyed something, it was definitely my fault because I didn't take care of my stuff.
She was a cat disguised as a small brown dog. Very independent. Very clean. Walked on the back of the couch. Had to have a perch to see out of the window or she would create one. Had no interest in people unless there was food involved. She could find the one person at the dog park who had dog treats. She was never mean or vicious, but everything was on her terms. But she was more compassionate than a cat. Never sick except for the time she tore her ACL when she was nine. She didn't slow down or decline until the last week of her life. She took very good care of me and after 2 years, I still miss her more than my husbands.
