Killing stray dogs

What is there to do when dogs attack civilians in a country without adequate resources? Police and veterinarians are killing stray dogs in Baghdad as there are too many strays to save and many are extremely aggressive towards people, often attacking them.
There is no mention in the CNN article of the SPCA International proposing how veterinarians in Baghdad would implement mobile spay and neuter clinics. Perhaps they can propose and pay for novel and painless ways to have some of these dogs euthanized instead of having them shot. Since these dogs are not dying instantly, they must be experiencing some moments of pain and sheer terror. I think using tranquilizer guns would be the least traumatic and painless for these dogs. Once tranquilized, the dogs can easily, safely, and painlessly, be euthanized. How much more would tranquilizer guns cost than shotguns?

The lives of people trump those of feral, aggressive dogs, but the manner in which this cull is being executed is completely unacceptable.

Appropriate tool to perform euthanasia?
