I have English setters and I typically trim up the feathering and longer hair around the ears and tail. I leave the body alone as I believe the guard and undercoat can get a little thin if trimmed too close to winter. The temps are expected to drop to the 20s later this week though it is a good 4 weeks early for here.

I also use Showsheen and several different brushes and combs as some work better on some snarl types than others. I also keep a pair of scissors and electric razor handy.
