Stella is 3 1/2 years old - she gets anxious at times, which has led her to show agression to the other two dogs in our household. It is a shame becuase other than this, she is a great dog. She is good towards kids, cats, people, etc. She is totally housebroken and up to date on vaccinations. Because of her anxiety, I would suggest she be the only dog in the household and no young children.
