The Bark Control Collars will probably be very effective.You could get 'bark collars'. Some give a very small 'zap' when the dog barks, others work with water, the dog gets a squirt of water. They're used a lot in the US.
The dogs learn very fast with shock treatment.
My dog was constantly jumping over the small gate between the houses.
I electrified the top of the gate with an animal fence controller.
First time he did not understand what happened and let out a yelp.
The second time he immediately learned and has not tried again, it has been 3 months.
I also brought with me the last trip here a Training Collar, uses sound and/or shock. Our dog was peeing on the metal gate and in the past I already had to have the large sliding gate repaired from it rusting out from the corrosive pee. The Training collar has a remote control, so I was able to control when to use it. Since our dog already learned not to jump over the small gate, he learned extra fast about peeing on the other gate.
If you do get a Bark Collar, don't leave it on the dog all the time, you don't want to punish the dog un-necessarily. Sometimes barking is a good thing.
Now if we could only adapt that technology for the drivers that never look to the left before they pull into your lane in this country.
Bad driver, Bad!
