My English Springer Spaniel requires an e-collar at all times when hunting and is out of an incredible pedigree of U.S field trial champions. When she see's the e-collar she knows its time to work and listen. In fact she gets so over stimulated by birds that only an e-collar would stop her from missed birds during her early training.
In fact i had her at a reputable breeder/trainer of UK English Springer Spaniels this past summer for training and a possible breeding in the very near future to one of her UK dogs. While the very experienced trainer was working with her came to the conclusion that my Elly has ADHD. The trainer had come across this before and recommended medication. The trainer put an an email together for my vet to read along with her early training methods and made a recommendation to try medication to treat the ADHD.
My vet was so impressed with the trainers knowledge and methods used to help Elly that he immediately put Elly on Clomipramine. That was 2 months ago and Elly is a completely different animal while hunting and as a family pet. She still wears the e-collar while hunting but i have yet to correct her since she has been on the medication. She is an absolute pleasure to be around and no longer requires constant correction. Her pedigree or breeding program that she came out of requires an e-collar while the UK dog breeding programs focus heavily on promoting a much calmer focused dog and the reason why many of the UK breeders do not use them.
My Uk Labrador Retriever import has not ever worn an e-collar and needs very little correction if any. She is completely focused on me at all times and obeys all commands taught most of the time. Would she be a field trial champion...possibly with a lot more work. Her pedigree is riddled with field trial champions going back many many generations. But we all know U.S field trials and UK field trials are different from each other.
In my opinion I prefer the UK dog because of a more pleasurable training experience. An e-collar has its place but its not for every dog temperament and could easily sour a dog if not used or introduced properly.
