i have to lurchers a year old and 7 months old, i don't have ppl round the house very often. so when ppl come round they bark non-stop, at them but dont calm down. i dont think the treat thing would work either as they bark because they are scared and don't get near the people coming in to the house. they go out alot and meet ppl and if its someone they know then they dont bark. am i just complaining about a normal dog thing?
