So, how do you suggest that vascular surgical staples are tested and demonstrated? How are surgeons supposed learn how to use them and gain confidence in them?

Dogs were anesthetized and operated on to demonstrate the staples. Arteries were cut and then stapled back together to show the effectiveness of the staples. Blood flow seems necessary for this. The dogs were euthanised after the procedure. I assume, because far more cuts/repairs were made than the dogs could feesibly heal from.

This was not some Mad Doctor, with a staple gun, stapling live dogs to the floor for his amusement.

This is not even close to the same thing as fighting/torturing dogs.
