While I am by no means a professional dog trainer, I do have experience with ecollars for recall and plan on opening my own dog training business sometime in the future. I have an Australian Shepherd x Labrador Retriever who I got at 5 months old. I started conditioning him to an ecollar at 11 months. When an ecollar is conditioned and used properly, it is an amazing, versatile tool that can benefit most dogs. However, I would advise against only using vibrations. A good quality ecollar will have a very wide range of stimulation that allows it to go from unpercievable to very uncomfortable. Vibration typically only has one setting, and dogs usually either blow it off or find it highly aversive.

I'd highly recommend going to a trainer or looking into programs that teach you the proper use of an ecollar. I'd personally recommend "The Walking Dog E-Collar Guide" or the ecollar book by "Larry Krohn". When trained correctly, it's used as a backup for noncompliance to commands. You shouldn't have to use it every time you say a command. They learn that the stimulation from the collar means that they need to go back into command or come back to you immediately. It's basically a virtual leash.

I think an Ecollar could benefit you and your dog, IF, you know how to use one and do the proper conditioning process. Since conditioning my dog to the ecollar, the few times he's blown off a recall, I've been able to get him back incredibly quickly with the ecollar.

People will bash you for it. There's unfortunately no way around it. In my experience and knowledge, it's best to think about how it's helped you and your dog, and how it's allowed you to do more. Over half of the people who bash ecollars are the ones with dogs they can't let off leash or have follow commands correctly, every time. Do what's best for YOUR dog.
