I've been worrying about this for a long time, and I thought I might be over thinking but I'd like to share and see what you think. There's a row of houses at the end of our garden and one of the occupants has a dog. Yesterday they put the dog out in the garden about 5 and at 8 it was still barking on and off, and whimpering. They've done the same this evening. It's not every day or at the same time but when the dog is left it seems like several hours and always outside. They are rather posh town houses so perhaps it's rented and the dog has to stay outside. I did ask the RSCPA if they could have a look in on it as I can't work out which house and that was after it was left for about 4-5 hours and I couldn't establish which house. It was a last option - I'd prefer to ask in person. I haven't heard anything and that was last summer. It's not so much annoying as I honestly think it incredibly sad to her it. Molly isn't in the least bit bothered. Sadly I can't see the dog as the gardens are very low down.
