I dont think the council will do anything if it just a few barks here & there during the day, after all its the only way a dog can communicate. Your diary will show that it is not constant barking during the day & night.
They may say the 6.45 barking even for a min or two is anti social, thats if they are been very picky!
Is there a way you can record them when you are out for a week or so? This will show you if it is more than you think or prove that it is very little if at all.
