Apparently certain household members with insufficient experience of the whole ‘actions have consequences’ theory will chew on a live electrical wire, get a shock just strong enough to be *interesting*, and keep going back for further experiments. (Rather like 10-year-olds trying cigarettes, or freshmen playing beer pong.) Repeated shocks to the mouth tissues eventually damage cells enough that opportunistic infections set in, or tooth roots die & decay. But of course nothing shows up on x-rays, and it can be nearly impossible to spot the entry-exit burn marks, especially since mouth tissues heal really quickly.

So… just in case, you may want to check all the household wires (don’t forget the kitchen appliances & the hairdryers) for chew marks. Especially since Fenway seems to be more interested in climbing than your previous dogs, and may have been able to reach wires you’d come to consider ‘dog proof’.

OR at least I’d be happy.

And yes, the problem of huge neck and tiny head makes a harness a good thing. Arthur hates his. He gets a choke chain instead when we go out. He can slip out of that too, but not so easily.
