Sorry, I wasn't sure where to put this   
My dog sleeps in a crate like this one http://www.wooddoghouse-4less.com/simages/crates1a.jpg and she's had it for a couple of years and it really pongs. 
She goes in there smelling clean and come out smelling like..ummm... dog (she normally smells more like roses  ) 
I have tried giving it a clean out and wipe down, buit it didn't really get rid of the smell. I even sprayed it with fabric refresher and aired it out for a day and it only helped for a couple od days. 
I have new blankets to put in it, but I want some suggestions as to if she needs a replacement crate or is there a trick to cleaning them? 
It wasn't cheap and other than the smell it's in prefect condition. 
Do you all replace your crates after a certain length of time?
