Ariadne sums up the process herself in the video, below I outline the path we took to create a reliable dog that can be trusted in any situation.

Poppy started a six session block of training with a developing reactivity problem. Once outside Poppy didn't give a second thought to Ariadne, she became focussed on sniffing, hunting and directing her frustrations at other dogs.
We began by building motivation to co-operate with games involving food and various methods of play. While building a motivation to engage we layered in a communication system and got to work with both loose lead walking and recall.
Once we had a good loose lead walk and a good recall, we layered the e-collar over the recall to make it bombproof!
Now Ariadne can walk both her dogs and take her two year old and enjoy the time outside as a family.
