You have stated two opinions, not the truth.
Dogs permitted by the owner to run loose? Owner negligence and irresponsibility.
Dogs that get out upon provocation on one occasion? Not sufficient evidence of an irresponsible owner.
It’s crueler to deliberately allow a dog to run loose, risking that either it or a citizen will be injured or killed.
I find it ironic that you are more upset about a chained dog than a dead dog.
Pretty soom you’ll blame me for those poor dead dogs.
