This is more of a product review than a blog. My neighbors have a pitbull mix and two chihuahuas that are extremely barky. They also bark at all hours of the day and night. My neighbor previously had a third chihuahua that was more barky than the other three put together. I complained about the most barky dog to the neighbor lady and that poor little dog was never seen again. I didn't have the heart to ask what happened to it. Rather than make one of the other dogs disappear (they're all rescue dogs as it is), I purchased a Petsafe Outdoor Bark Control. It plays an ultrasonic tone when a dog barks that curbs the barking behavior. I was expecting the barking to taper off in a few days. I was wrong. I put it in the tree next to my house and by the neighbor's fence. As soon as I turned it on the barking turned into an occasional woof and some growling. In the last hour I have heard less than a dozen woofs from what was previously a bark factory. On top of this humans cannot hear why this is happening and we look like good patient neighbors. This has really worked for us. It might work for you if you have a similar problem.

Pardon the run-on paragraph above. I did not sleep much last night (windows open + barky neighbor dogs ≠ good night sleep). I think I'll have a much easier time tonight though.
