Unless she has any ongoing heart disease or is a breed with a genetic susceptibility to heart disease, this supplement is not likely needed. I recommend to discuss using the supplement with your regular veterinarian as they are most familiar with Bella and her history. Best of luck and please feel free to post any additional questions.
