I didn't like the Sweet PDZ at all when I tried it on my chins. It felt like it made the fur thicker and harsher feeling, like it was burnt. I noticed the fur clumping a lot too.
I have tried it as a dust and yes, I have noticed that it dried out Herby's coat. I now am using the Blue Cloud and I use the PDZ as an odor controllant mixed with her aspen shavings. I also noticed that it dried out my hands when I would hold her..
