I swore I would not cut Xena's hair, but after two trips the the ER and two shaved front legs later, I cut her hair so it would be more even.  Not super short, but about 2" all around her body and left her head hair long.  I have to say, it's soooo much easier to brush/comb now.  I am convinced it was the puppy hair that made it difficult before.  Her hair just feels much better.  I will be letting it grow to full coat though.
