I have a 10 month old Formosan Mountain Dog that I have had for 2 months. I adopted her from a rescue that had her sent from Taiwan, at 7 months old. She has been making excellent progress towards becoming a well socialized and well behaving dog, but lately, for about 5 days, she has been acting stressed in our back yard. There's some new gopher holes in yard that she is very focused on. She is distracted, won't listen, won't go to the bathroom outside (she had her first accident inside this morning) and she threw up for the first time today as well. I'm working on getting rid of the gophers, but is that normal behavior for a dog when encountering "outsiders" in her yard? Thanks!
