Re: OT Electric bark collars??? pros and cons
I also prefer to train them when to bark and not. Barking at the correct time with praise and/or a doggie biscuit, a command voice of "no bark" at the incorrect times. My Jack Russell terrorists have done well with this training.
I agree with LEVE on the use of a newspaper.
Some professional obedience trainers may suggest other methods.
Barring that, and you don't want any barking at all, there are "no-shock" collars out there that will release an unpleasant scent (to dogs, such as lemon) when the dog barks. My veterinarian wife prefers this collar to the shock collars. Do a Google search.
Best of luck.
