Brandi - Schnoodle puppy

We bought the extra small set for our 8 week old puppy Brandi. We were flying her home from Branson, MO to our home in Bradenton, FL. She was only a little over three pounds. On the way home her muffs kept sliding off the back of her very small head. We have another flight this weekend to Boone, NC so I set out to figure a way to keep her muffs on. I just cut a sock and slid it over her head. It seems to work well so far, I will try and report back after the holiday weekend. Mark C.
