Hello, thanks for your question today! I am Dr. Drew, and I am a licensed veterinarian. I'll be happy to help you in any way I can.
Given that many dogs live to 15 years or more, I do not have any good justification for suggesting that you stop heartworm prevention at 12 years of age. If Lucy had a serious disease, such as kidney failure or cancer, for example, and her expected survival time was 6 months or less, then I could support the idea of stopping heartworm prevention.
I think it would be tragic to have an otherwise healthy senior dog develop heartworm disease due to a voluntary choice to stop the prevention.
