About two weeks ago, our golden seemed to have a sudden change of personality. She wants to be outdoors almost all of the time and when she is in the house wants to crawl on the furniture and the people. She always used to go into her crate at night willingly and settle right down, but now she protests and resists. The only thing I can think of that changed in our household around that time was getting a new water softener, but I can't see how that would be related. She is 2 1/2 years old and was fixed when she was a puppy. Any thoughts?
