Usually, in survival analysis, it means that at any point in time, the likelihood of an event (e.g. death, heart-disease, whatever they're measuring) occurring for dog-owners is 76% of that of non-dog owners. The risk varies from time to time, e.g. with age, and it's 76% of that risk. If the risk at a certain point is 10% for non-dog owners, it's 7.6% for dog owners. It's not like dog people are immortal.
