Hello,
I live in a terrace and my neighbour has recently adopted a 6 month old puppy they have got from a charity bringing over Romanian dogs.
The dog yaps a lot - very much a reactive dog, I.e if we go in our garden and he's in there he barks and growls, barks if you take your bins out, shut your door etc.
However the barking is not prolonged for hours, it's short bursts of barking but a lot. If I counted the single barks as well I would say he probably barks around 50 times a day, with some barks happening in short succession and then other hours it's quiet.
I spoke to the other adjoining neighbour to see if it was bothering them and they said it is to the extent they had contacted our neighbour to see if she was leaving the dog on its own, and our neighbour confirmed she had started leaving him for short intervals.
I don't want to go to the council, but since I have an ally, if this is too much I will mention to the neighbour. She brought it up with me before saying she is training him, but so far there has been no difference.
