Neighbour’s guide dog seems to hate being left in alone. Never hear a peep out of him (the dog) usually, but if neighbour goes out without him, he seems to bark on and off at anything that moves outside (and as we live on a main road, that’s pretty frequently) till he comes back. Happens most days for up to 3hours at a time, ( family come to take him out shopping etc) Didn’t bother me at first but Im finding its starting to get to me. Afternoon to myself, settled down with a good book, the dog has been barking on and off since midday. Don’t want to stress my neighbour out by complaining as he’s blind and has come a long way in being able to cope independently. Do I just suck it up and put in ear plugs if I need quiet as it’s only a few hours a day and never at night. Or could an anti barking device help? Has anyone ever used one successfully, and if they do work, does it cause the dog any pain or distress?
