yeah, i was thinking about that too, do you think maybe just using it on her frizzy dry pants then would prob be better?
Honestly, that's just how Sheltie pants are - harsh and "frizzy". You won't do any harm by putting leave-in on them to try to make them silky-soft, but I suspect it would be a rather losing proposition. Besides, that harsh texture really helps the coat repel dirt.
I got it last Christmas and have used it twice. It's good stuff though. 
We have some jars and pots that are positively ancient, but the stuff still works - it generally doesn't go bad (and if it does change in consistency or smell, you can throw it out).
My grooming kit here in NJ consists of a greyhound comb, a slicker, a pin-brush, straight and thinning shears, and a spray-bottle of water... oh, and a bottle of #1 All Systems cleansing shampoo I poured out of my mother's 5-gallon bulk bottle. It's just enough to keep a retired house-dog clean and neat.
