I'm actually not sure about that. If they need quiet, they'd shoot the dog quietly - but apparently the dogs had not yet all died by the time the interview was held, so they were alive far, far longer than could possibly be of any benefit to a special ops team.
More likely that a neighbor did it, sad as it is. Maybe the guy that got shot, maybe somebody else who got sick of a pack of wild dogs trying to attack them for using a public beach. It's one thing to "love dogs" and another to tolerate a dangerous pack of animals in your neighborhood that have been spoiled by a paranoid nutcase.
With a silencer, I guess. What do I know? I've never shot anything nor do I plan to - but it seems a silencer would be quieter than a dog that was still dying of poison two days later.
