This article is from the Obedience Trials, by Cindy Tittle Moore with numerous contributions by others.
Common handler errors:
1. Not knowing that if dog breaks the owner SHOULD NOT return to the
line with other competitors
2. Late leaving dog
3. Not returning to heel position
4. Positioning the dog or touching the collar (you can't touch them)
5. Handler zeros in previous exercises and doesn't return for Sits
and Downs (you must return or ask the judge to be excused).
6. Extra signals from across the ring.
Helpful hints:
1. Don't position your dog on the crack of the mat or (if outdoors) a
high or low spot.
2. Look around before getting started and pick up any debris near
your dog to avoid sniffing.
3. Clip your armband to your leash - and lay down so it won't get
knocked or blown away.
4. Make sure that your dog will lay down straight (especially if you
are showing a large dog) to avoid having to reposition your dog.
5. When the judge asks if everyone is ready before the exercise
starts SPEAK UP, if you aren't ready - don't rush yourself and
chance a zero.
6. Cross your arms to make the exercise look different than the
recall.
7. If your dog doesn't go down on the first command, give another -
the exercise doesn't start until the handlers leave (except for
rough handling,etc).
8. Make sure you have your dogs full attention before leaving him so
he doesn't get up as you leave.
