`Comparing the Derrett and Mecklenburg Handling Systems By the Clean Run Staff © TTL AcTion PhoTogrAPhy, MichAL Krejci, MeTTe Björne PART 7 Serpentines The two main systems used in the U.S. and Canada right now originated with Greg Derrett (also called the Derrett System) and Linda Mecklenburg (also called the Awesome Paws Handling System or APHS). The purpose of these articles is to compare and contrast the cues between the two systems for informational purposes. We are not going to try to prove that one system is “correct” or that one system is better than the other. Both systems are proven and both work as a consistent handling system. This article series is designed to help you understand what the differences and similarities are so that you can make informed decisions on which may be the better system for you or your students. This series is also not designed to fully educate you on the intricacies of each system. There are resources available for both handling systems that are intended for this purpose. For the purposes of this series, when referring to obstacles, we will be using jumps since handling cues have the most effect on a dog’s jumping trajectory. APHS also refers to other turning obstacles such as tires, straight tunnels and chutes, but in order to be consistent between the comparisons of the two systems, we will refer to jumps. In this article, we will compare the use of serpentines. A serpentine is a series of three jumps that are all handled from the same side of the dog. The traditional pattern for a serpentine is shown in Figure 1, but there are many more configurations as shown in the other diagrams. As a review, the cues available in each system are shown below. 1 2 1 3 This is a traditional serpentine pattern. In both systems, the handler stays on one side of the jumps. Derrett System Greg Derrett defines a serpentine as any three obstacles in series where you can theoretically do a front cross both before and after the middle obstacle. Another way to define it is a three-obstacle series where a right turn follows a left turn (or vice versa) at the middle obstacle. This includes curved tunnels. If the dog is exiting a tunnel that curves right and needs to be on the handler’s left, for example, this is also a serpentine and needs an arm change for consistency. In Figure 2, the handler can replace the front crosses with serpentine handling: a right arm creates a right turn from #1 to #2 and a left arm creates a left turn from #2 to #3. A serpentine uses the same arm changes, but a different positional cue. The positional cue for serpentines is the landing side of the middle obstacle, on the far wing as shown in Figure 3. Derrett System Use of Cues for the Serpentine Type of Cue Actual Cue • Landing side of the middle • Positional cues obstacle on the far wing (relative to equipment) • Acceleration/ deceleration • Arm changes • Shoulders (blind-cross body line or BCBL) • Legs • Verbal cues • Eye contact • Deceleration • Two arm changes; one to cue each turn • Jumps #1 and #3: facing the direction the dog is going; jump #2: turned into the dog • Leg closest to the dog • Dog’s name • Keep your eyes on your dog Clean Run | September 09 36`
