There was no difference in the number of verbal cues used in each group, but Control 2 used fewer hand and lead signals, and Control 1 made more use of these signals than E-collar group.

There was no significant difference in the proportion of command disobeyed between the three groups, although significantly fewer commands were given to the dogs in Control 2. These dogs also had shorter response latencies than the E-collar group. Control 2 achieved significantly better responses to both “Sit” and “Come” commands after a single instruction in the allocated time. Measures of training efficacy included number of commands given to elicit the response and response latency. These were the two most common commands used during training, with improving recall being the target behavior for the subject dogs.

Data collection focused on dogs' response to two commands: “Come” (recall to trainer) and “Sit” (place hindquarters on ground). The 3 groups were: E-collar-manufacturer-nominated trainers who used electronic stimuli as part of their training program Control 1-the same trainers following practices they would apply when not using electronic stimuli and Control 2-independent, professional trainers who focused primarily on positive reinforcement for their training. A total of 63 dogs with known off-lead behavioral problems such as poor recall were allocated to one of three training groups (each n = 21), receiving up to 150 min of training over 5 days to improve recall and general obedience. We assessed the efficacy of dog training with and without remote electronic collars compared to training with positive reinforcement.
