Have name-changed for this. I have a 20-week-old pointer pup who is very lively and bouncy but doing brilliantly with training (we do gundog and general obedience classes) and in general is a pleasure to have around. I work from home so pup is rarely left alone, though I make the effort to put him in another room by himself from time to time or leave him outside for a bit while I'm working so that he gets used it. I've built this up and am confident that he can go 2-3 hours quite happily now. However, today a neighbour (from a few doors down) came round to complain about him barking. I know he did bark yesterday while we were out as he was (unusually) barking and upset when we came back - I'd tried leaving him outside in an enclosed section of our garden as he'd been settled happily outside there before we left (he had access to water, shade, and shelter). Clearly that didn't work and I explained that to our neighbour and apologised and said we'd keep him indoors in future as we had done previously (he's usually curled asleep when I come back). However, she said that the barking was an ongoing issue, that he barks every night until 11pm, and that she knows it is the same dog as it was the same bark as yesterday. I told her that this could not be the case as we don't go out in the evenings (we have young children - our last night out was 3 months ago, before we even had the pup) and she said that she knew we had grandparents babysitting! I'm really worried that she has an issue with our dog in general (for some unknown reason) and that she will take it further. Has anyone else had a case of mistaken dog identity - any advice on what I can do? I've knocked on our immediate neighbours' doors and no-one has any complaints (though apparently the complaining neighbour is known to be a troublemaker). I should probably just ignore it but I'm so worried, is it worth pre-emptively contacting the council or is that a bad idea?
