My son needs gromits, his hearing has been bad for some time. He is 5 and has no road sense because he cant hear the traffic. Friends have told me gromits dont always work so I was wondering would a dog benefit my son? His hearing is very poor and I'd rather make the start with a dog during the holidays where he has the time to get used to it. I'm quite ignorant about this type of thing so forgive me if I sound stupid but I know nothing of it
