When you say that e-collars work where conventional methods fail, I'm afraid these people just don't agree with you (The Association of Pet Bahaviour Counsellors)
If people know they are restricted in the kinds of fences they can build, then in makes no sense to have a breed of dog which can jump or is bred to dig, like a terrier.
I do understand Julie that you at least did try it on yourself - however, I still feel that you should have built a secure area in your garden for the dogs - you've enough space - what on earth are you thinking of though, having deer wander close up to your house when you've got two labs? It's just asking for trouble.
Iza - You're right - there are differences between the US and the UK but I've yet to come across anyone concerned with animal welfare who advocates the use of these horrible things - American welfare organisations certainly don't.
If the British Military, the Police, Search and Rescue, Guide Dogs for the Blind Association and all the major animal charities in the UK condemn their use - then they're doing it for a reason.
It's not a question of whether to agree to disagree, it's a question of who to trust - and I tend to trust people who put their money where their mouths are - I'd trust a police dog handler who's dog sniffs out explosives, rather than someone who thinks it's okay to give an electric shock to a puppy, just because it gets under the fence.
