Yeah, I only have to wash my CsV when he finds and immediately rolls in a dead fish, cow poop, mug bog etc. (Which is annoyingly often haha.)
Besides those times he's amazingly always squeaky clean and gorgeous!!
The one and only grooming tool I would ever recommend and since I own a CsV, German Shepherd and used to have Huskys, is a FURminator oh my god there's nothing on Earth better for getting that under coat out trust me!
You can buy one at any pet shop or groomer here in the US but also over the internet.
Happy grooming everyone!!
