He was a fighter until the end and always very dignified. He has had a good life and a successful one as a police dog. Just think of all the bad people he managed to put away.
"Bad people." Hm. That's a loaded statement. While I'm very sorry for Inspector Higgins' loss, I would like to point out that Max might [would probably] be here now if he hadn't been trained and used on a daily basis to violate the privacy of people who are obeying all the laws of common sense [by not doing things that victimize other living beings]. No one has the moral authority to tell other mentally competent and consenting adults what they may or may not smoke, snort, swallow, inject or otherwise ingest in the privacy of their own homes. The "War on Drugs" is a transparent farce--an excuse for corrupt and fearful governments to assert physical control over their populations. It is also a massive and perverse monument to the power of corporate pharmaceutical, alcohol, and tobacco lobyists. Max is its latest innocent victim. His life could have been much more fulfilling if he had died of tumor caused by sniffing explosive residues.
