A neighbour has a dog which he seems to let out early in the morning (poo time or whatever) in his garden near to us. Sometimes this is at 7am but sometimes it's before at 6.45am. The dog appears to be trained to bark to ask to be let in the house. We don't get up till 7.15 and sometimes are woken by the dog. We have asked him once nicely to stop and he made no comment - took no notice- anything we should do if it carries on?
