I have two dogs who seem to bark at random things when they are in the house/yard. It seems that one dog will see/hear something and let out one bark, then the other dog hears him bark and gets excited and also starts to bark. Before you know it the two of them are barking like crazy! They seem to play off one another. By themselves I'm not sure they would bark as much. The dogs are a dachshund and a chihuahua so they are prone to barking anyway. I just want to figure out a way to get them to calm down before it becomes a barkfest.
