Let's not forget that drug-sniffing dogs are trained to give positive indicators. They don't sniff for drugs, they just give cops probable cause to search your luggage if they want to.
This piece doesn't have the typical copaganda headline, but it's copaganda for sure. Just saying.
Your points may be valid (immaterial to my comment), but you're not doing yourself any favors by using such words. It's a red flag for "ideologically-driven zealot".
...in America.
Do you have any evidence this happens elsewhere?
The personnel in the airport have limited searching capability. So if dogs are sending some people, it reduces your probability of getting searched.

Dogs are not complex animals, and they are rewarded for positive indications regardless of whether the person who is searched actually HAS drugs or not. Since you have a constitutional right not to have someone just point at you and say "Hey, lemme search your bag because I don't like your face", they are basically an excuse to search whoever the cops want.
Also privacy is one area that demonstrates Jevon's paradox but in reverse because you are the resource. Increasing expenses can be the best protection for privacy as it forces attackers to give up.
Are they thoroughly tested for all cases? I honestly doubt it. Just incinerate them and breed clean ones. And it's not like their anti-coagulant abilities are irreplaceable. Sure, they come in a convenient package but that's all.
Could also be the sales price which might be higher there than elsewhere.
I'm by no means an expert and it's just a guesstimate.
