UK dog walkers, beware of deadly toxin!

[Tobi]

It's possible this toxic substance has been cleaned up by now, but I have heard no news about clean-up operations on Britain's beaches. And that would have to be very thorough to get even small pieces (such as the marble-sized piece which the little Schnauzer ate) So it's wise to still be careful.
Antifreeze/Coolant is an on-going toxic hazard for dogs and cats (and probably wildlife as well)
