Fine weather and dog madness

The few days of recent fine weather have brought out the dog walkers, however now there are hundreds of loose dogs on my local beach, the real problem is many of these poor dogs haven't been outside the house for weeks with all the wind and rain.   The dogs are now so excited they are going for each other and attacking pretty much anything going past. 
Now common sense would suggest the owners put the leads back on, but oh no!,  that's too easy.  No the moron owners just run and grab the collar and pull the dog away, wait about 3 seconds and let go... Yep you guessed it, the dogs are fighting again in about 4 seconds (great fun to watch the owners trying to catch their dogs) 
There is a serious issue here though, theres young children playing on the beach too, sooner or later someone going to get badly hurt.  I'm sorry but dogs really do need to be kept on proper leads all the time (not 3 miles of nearly invisible string either) so they are under control.
Talking of long silly string leads a few days ago I watched a young couple with a large dog being dragged along the pavement, unfortunately the dog on the end of about 30 foot of string was walking down the middle of a busy road.  The couple seemed unwilling or unable to get the dog back on the pavement (they were not trying when I watched them)  but even if they wanted to those thin leads are really hard to pull back in, the strings so thin you can't grip it properly.  Another good reason to ban the dangerous things.
