What is the recommended age to with a puppy to start using the electronic training collar?

I start my dogs on the ecollar between 4-5 months.

We have an extensive q & a section on the website, I would suggest you spend some time reading there

http://leerburg.com/qaelectric.htm You’ll learn quite a bit, even though not all the questions are geared towards 6 month old puppies.

I’d also recommend Electric collar Training for the Pet Owner.

Let me know if you need help selecting the right ecollar (if you haven’t already purchased one).
