Hi new to this website but was jut wondering if anyone could help my British bulldog Rocco is 5 but has recently started barking n howling/moaning when we leave him home alone. Neighbours can hear him all day nothing has changed within our life's to bring this behaviour on we have always left him home alone since he was a pup have tried leaving in chews toys nothing seems to work any help would be much appreciated before we really start to upset the neighbours thanks xx
