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

Never allow someone else's dog into your home. Dog owners are worse than toddler owners. 

They laughed and thought it was cute.

Can’t help you with the dog, but there are recommendations regarding what rug or carpeting works best to tame first reflections off the floor. 

Try this as a search:"What factors should be considered when choosing a floor covering for sound absorption in audiophile environments?"

I use a half inch cut pile wool rug on top of a 3/8 inch felt pad.  

Good luck with the dog. I feel your pain. 

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.
