I'm pissed off

Because my computer was pissed on!

I usually sit on the floor in front of the sofa so I don't have to stretch out and can put a small table on my lap and alleviate the need to move my arm to control the mouse.  When I'm done,  I close my laptop and put it on the coffee table in front of me.
Last night,  I set it on the floor while I took a bathroom break, and turned the lights out and went to bed leaving it on the floor when I was done. Open. ONE of the dogs peed on it.
I don't know which one,  so I can't shoot it,  but I am posting from my cell phone until I can figure out a solution.
Bear with me, and if my pics are a little off and my posting slacks off,  now you know why. ..
Doing this shit from my phone SUCKS!
