I find 3 dog training systems, and anti-bark systems, but not a combination of both. I would like to be able to correct individual dogs, or all three
from a remote, or when I am gone have the auto anti bark do the correction for me. We are moving to a new house in a much better neighborhood
and we do not want to be "that guy". The dogs have unfortunately been trained by one of our neighbors here to "bark for a treat" as she likes them
watching her property that she does not live in that is adjacent to ours. Hoping to tone them down at the new house, as I dont think the quiet neighbors
will be as happy with their antics.
My internet .02 to follow:
I've found that if you train a dog to bark for a treat you can train them to stay quiet for a treat too. My last dog would show me her "war face" and then stop the barking when I said "quiet". The dog could be going nuts at the door when someone came knocking, but a simple "quiet... sit" would have her on her bottom and waiting for my next move.
IMO the dog barking at folks getting too close is it's job. It's your job to set the boundary for the dog.
