Can't do links but basis of story:
Southend Beach last week
2 out of control rottwellers according to DM .One attacked a 7 yo boy in the water.
Grandmother had to pull the dog off him.She feared he would drown.
Police looking for owner.
I've no reason to not believe the story but at the same time, take the Daily Mail with a very large pinch of sodium chloride.
Point of my post.
We had taken the DCs to Southend on Sunday before last.
My dog phobic DD kept asking "Is it off season for dogs on the beach".
I assured her it was (I hope this was right)
If my DD had witnessed this or it had been her and the dogs. OMFG
I know I can't mollycoddle her and protect her 100%. I know 99.99% of dogs are fabulous creatures.
I tell my DD that dogs have every right to go to the beach (in dog season) to the park and even walk down the street!
She is getting better (slowly) with dogs, but there are places I'd avoid. Wouldn't take her into woods as I know there are off-lead dogs and as we can't beat them (not literally!) we won't join them 
But if my child wasn't safe on a family, busy beach?
for boy who was bitten/mauled.
