I foster American Pit Bull Terriers (APBT) and their lower center of gravity and high density could present a challenge to some speaker stands.
Some examples at:

Definitely fill with lead shot, especially near the base of the stands. Please try to move the speakers to avoid problems. Dogs try so hard to please you and they can read you much, MUCH better than you can read them. Disappointment in them, ESPECIALLY APBTs, really hits them hard. You should also work with an accredited Animal Behaviorist that knows your breed (it makes a difference) about strategies to deal with this and other issues. I simply tell my guys "BACK" (this moves them back a few feet) followed immediately with "SIT" then quickly give them all deep loving hugs when I come in away from door. This removes issues and gives you an uplift that helps the day's problems melt away. Actually this problem could present a real opportunity for a closer relationship with your dog.
