Oka, so he was in the basement and got out. How did the dogs not pick up the scent????? He is wounded???????

The torn tarp. Look at the video of the robot tearing the tarp.

It doesn’t look torn at the beginning of that video.

So you boating people out there...

does this look like a torn up tarp before the robot tears it up.

The dogs did pick-up a scent but then lost the scent.

If you look at the video you will see a square patch (dark lines) on the port side of the boat on the tarp. This is an access door for the tarp. I don’t know but I assume the boat owner may have noticed straps to the access door was cut.
