I got two new puppy brothers about two years ago. I took my longarm in for servicing last week and found they (in their puppy days) had chewed into the cord which was underneath the table, exposing the wires. It was by the grace of God that I didn't have a fire also. Just something else to check now and then. I'm so sorry for your loss. I had a house fire years ago and I still think of small things that were lost in it. My prayers are with you especially for the patience you will need to deal with all this.
Lots of hugs......
