However, the original post didn't mention cousins, children (multiple or just one) or even plumbers.
Someone mention plumbers? Last seen with Rhonda. Is he back? I've been looking for him! 
Oh. You lot still here. Hello. I've been doing a very quick (and not very thorough) catch-up. I noticed someone thought that the 'dog people' possibly didn't have children and so thought of their dogs as substitute children. I'm one of the 'dog people' and I have children. I also noticed someone wanted to kill (I think) Outraged's dog. Really? That's outrageous. Not okay.
I've been loath to say this because too many 'hypotheticals' stress me out (I want to jump up and down and yell "It's not real, get a grip") but here goes.
A long time ago my dog, of that time, saved a small child, who fell into the sea. (This bit is real). I'm not saying that the child would have died if the dog hadn't been there, nor I'm saying that a human couldn't have taken over from the dog and finished the saving. I can't know those things, but I do know that the child's life was in real danger and the dog completely saved the child. It was very quick and surprisingly undramatic. Children paddling at the shore, some climbing on boulders, and one fell into deeper water. Quick as a flash, my dog was in there, grabbed the child and swam ashore. It was touch and go whether she'd manage, for a second or two. At first she tried to hold the child upside down in the water (wouldn't have done at all), then the child tried to drown the dog (they were probably nearly the same weight), but they both quickly got the hang of it and by the time the adults were on their feet and in the water, the dog already had the child in the shallows. It was lovely and of course everyone was very pleased. 
Here's the hypothetical bit. If that dog of mine and a stranger were in the burning building and the (nearly drowned) child's mum could only rescue one, who should she save?
Now, where's the plumber?
