Is there a whatspp group for your area? Might be a better way of finding out? I'd try and find out where the dog was. Honestly, nothing worse than dogs barking non stop - they can't be happy and it's impossible to think straight. We used to have a neighbour who would leave her dog out - we used to bark at it when it was cold or it had been out for ages and then she would take it in. You can contact the council - they will want an address and evidence. Note, a dog can be kept outside if they have a house and access to food/ water.
