For close to 20 years Fox has shown the weekly show, “Cops” and since then there have been many spin-offs (best police chases, best police videos, etc..) and quite often you see the K9 officer being involved (nothing beats a video of a K9 taking down a criminal). 😉
From what I’ve seen, the vast majority of these K9s are either German shepherds or Belgian malinois. In all the years of watching Cops, I think I can count on one hand the number of non-malinois and non-GSD K9 units in the show (once I did see a Dobie and it was interesting to watch).
Why GSDs and malinois? These two breeds are easily trained (both being very intelligent), have stamina to be able to work a long day, are herding dogs (so they are very attentive and protective to their “pack” (meaning the K9 handler)), have a relatively long working life span (roughly 7-10 years for a GSD, 10-15 years for a malinois), can be very powerful (their size, the momentum they can build up while running, and powerful bites), plus the sight of a good example of these breeds can be extremely intimidating.
Don’t think these two breeds are killers – they make great pets (GSDs are far easier than malinois, though) and raised correctly they can be a very loyal companion to any family.
