That explanation is as flawed as it gets, narrow minded and biased; people making a lame pathetic attempt to explain murder to fit their own needs and "moral dilemma".
Who exactly are we to choose to make it acceptable to murder cows, pigs and sheep and say it's appointed species under appointed circumstances (to feed our fat stomach) and get all upset when someone slays a dog because mostly they are pets but in this case it wasn't the family's pet.
One could argue a cow provides lot more to us than a dog, milk and the several other dairy products like cheese, yogurt, ect..ect..and if anything cows shouldn't be murdered based on what you're saying.
Perhaps some people need to rationalise it in different ways rather than their narrow minded ways and getting so upset over it.
Like the family said it wasn't their pet dog, it was given to them by some family and it was a nuisance who tried to bite several times hence the decision to umu it before it tried to umu someone's kid.
