need r8500 Power adapter replacement

Hi guys,

Unfortunately my puppy decided to get into my computer room and cause havoc with power cords (didn't get hurt thankfully but he decided to start chewing on the large parts of the adapters, only bright side is he didn't pee on any of it!)

Anyways, I cannot find a replacement power adapter online for this specific router. Is there any place I could find one or can netgear support help me purchase another one (I can't be the only one who's needed a replacement power adapter.) I don't want to get the wrong one either and short out this unit.

So if there's anyone who knows where to find one or could help me find the right person at netgear to get in touch with I'd really appreciate it!
