Well technically Bella is still a puppy at age 10 months. She has basically calmed down into a good dog except for the occasional urge to dig in the back yard. She hadn't destroyed anything in the house in ages but yesterday when I was on the phone she started chewing on a bed pillow. She had never done this before! I am wondering if it was just a ploy to get my attention, which she got....instantly!! I think maybe at one year of age they enter into adulthood and then hopefully some sort of maturity. At least I am hoping that is the case. Maybe by next spring my yard will not look like little bombs have been dropped in several places.
