my dog recently learned how to scale a bit of rough ground at the back of my yard. the problem is, when he gets up to the top he can see my neighbours two dogs and he stands barking at them. the climb up is too vertical and high for me to get up so aside from calling and coaxing him down i have to wait til he decides he is ready. now one of my neighbours has complained to another neighbour about it. i completely understand her frustration. i feel the same, however i dont want to keep him in the house all the time, i think he should be able to stay out when the weathers good and explore his environment but what do i do about the barking? should i get a barking collar?
