Shaggy rug Pet-friendly alternative to a shaggy rug for room acoustics?

My daughters old boyfriend parents came over our house for the first time and brought their dog with them. He ran right up to my amplifier and pee'd right into the vent holes onto the electronics. I couldn't believe my eyes at the stream he produced. They laughed and thought it was cute. 
 

Hope you had an opportunity to visit their house. If so, what did you pee on?

I'm like the puppy every 2 hours I gotta go😃.enjoy the shag ,carpet pad and get a blue light and waterbed.maybe a disco ball.that will keep the relatives away.

It's an older rescue dog with a history of abuse. He spent most of his life confined to a cage and became accustomed to relieving himself wherever he could. We're still working on the issue, but for the time being I need a practical floor-covering solution for the listening room.

Ideally, I'm looking for something washable, lightweight, and, if possible, non-absorbent. The size I need is approximately 8 ft × 8 ft.

I have an idea.

The carpet I currently use weighs about 40 lbs and is quite rigid, so removing it after each listening session is a real hassle.

What I’m looking for instead is a soft, sound-absorbing blanket that I can easily lay down during listening and then remove and store afterward.

Ideally something professional or studio-grade that others here might recommend for this kind of temporary acoustic treatment. Maybe a wool blanket ?

Has anyone tried something like this successfully in a listening room?

simple. Audio room is a pet-exclusion zone.
