Just because you think 'the council will not be interested in 20 minutes a day of yapping' - and it's 'no time at all for a dog to be yapping,' that does not mean the OP should not report it. It's SEVEN in the morning. An anti social time. I am sure they will act on it.
Will it be OK with you if I come round your house on Sunday morning between 6.30 and 7am, and bang on your front door for TEN MINUTES, waking the whole family? And because it's light then, you struggle to get back to sleep?
And then at around 11.30pm when you're all tucked up in bed fast asleep, I will come bang on your front door, for another 10 minutes, waking you again, when your family have work/school the next day? Will that be OK???
Yeah I thought not 
Someone allowing a yappy barking dog to continue the yapping and barking is a bad, entitled, inconsiderate neighbour at best, and a poor dog handler who can't control their mutts, and think everyone who doesn't like them and is affected by anything they do can just deal with it! 
These types are usually the same ones who let their dogs jump up you when they are out, and let their dogs shit all over the pavements, and to hell with anyone who is affected by it.
