How do you keep a dog from chewing the plug and pigtail off of your trailer? My fathers dog chewed mine off, now I have to splice in a new pigtail, and feed it all back thru the tongue. ARGH. Ive been thinking of a metal box attached to the tounge to lock the wiring in.
Moving the trailer to my house isn’t the answer as we have both houses inside the same 6-acre fence. The dog has free range inside the fence and is the smartest most brilliant infallible creature to ever walk Gods earth. 
Just ask my dad. 
Plug it in to 120 when you aren't using it... dog will only bite once more.
Put some Dave's Insanity Sauce on it.
be careful with the hot sauce. My mom's vet told her to do that to the wooden horse fence's. guess what? both old mares LOVE hot sauce.
maybe you could run it through some spare braided stainless line before you put the plug on this time around... either that or just make a 3 or 4 foot "jumper" with male plug on one end and female on the other (they actually sell those premade at tractor supply and walmart and etc) and just put the trailer plug out of the way, and use the jumper to plug between the trailer and the vehicle. keep it inside or in the vehicle when not in use.
Thats how I set my trailer up to start with, in case I ever need to tow it behind something that uses a different plug than flat four, I can just build a new "jumper".
Shotgun?
I used to have a 18ga steel door knob crushed flat and with teeth holes punched through it. The boy was having a bad day.
The removeable jumper is a good idea, or put up an electric fence around your trailer. That will work.
Seriously paint it with ammonia....dogs hate it, works to stop them peeing where you don't want them to also.
how about a mounted plug on the trailer (rather than hanging free) and use the "jumper" idea above to plug the trailer and truck together? No hanging wires should equal no chewed wires

square metal conduit box from the electrical aisle of HD, couple of appropriately sized Ubolts to fit the trailer tongue, rig together a few wingnuts to hold the coverplate on the junction box. Tada. coil up the pigtail and put it in the junction box when finished towing.
Keeping the jumper/pigtail in the glove box or toolbox on the trailer is probably better/easier, though.
Use electrical tape to wrap the wires instead of bacon?
I have a fence charger
I was thinking about putting the pigtail in a box that I can close, hadnt thought about an electrical box. I also thought about some old steel braid line i have but it is too stiff.
