There are a number of Dogs in my neighborhood, It falls on the firstDog 2 alert the others, if trouble is a Paw, There is one Dog, He is a yappinDog, and the ofver Dogs no,if he Yapps, 2 take it with a less than the urgency a standard alert would require.Some of us use different methods, . Many times I’m “First on the scene” and of coarse use the Roo , and give a full description of the situation, with detail ( pun) . I only Bark if the intrusion is M N it .. Ofver Dogs use the continuous Bark method, which can lead to confusion and Mistrust, . This is the reason I wrote ” U 2 can Roo ” which will be available soon on Amazon, . If your Dog is a Barker, Maybe this Book is 4 U,
