Animal to animal transplants only ever occur for research purposes, not life-extension of family pets. However when researching for human transplants, many animal transplants have to be done.

yes many transplants have already been performed
In the UK, approximately 200 to 300 heart transplants are performed each year. The number can vary based on factors such as organ availability and the overall demand for transplants. Efforts to increase organ donation rates have been ongoing to help meet the needs of patients awaiting heart transplants.

Within transplantation surgery, there is nothing to be "sure" about, even when working with allograft transplants. With xenograft transplants (which are exceptionally rarely performed), risks are much higher and there are additional risks which do not occur with allograft transplants. In either case, there is no way to be "sure" of a good outcome, due to the many known and unknown random variables which affect outcomes.
No studies have been done
