Dogs being dogs, whether pedigreed or not, can't help being themselves whenever they spot a lamp post or a car by the way, even if the latter be an object of desire for millions.

You might have seen them raising their legs and relieving themselves, supremely unconcerned about what you think and then pattering away nonchalantly.

A reputed car maker has now equipped its latest model with a technology to keep these pesky canines at bay -- giving them a nasty 200-volt jolt.

The German giant BMW described its invention, the electric sting as 'relatively pain-free,' but enough to deter dogs in future, according to a metro.co.uk report.

The energy generated by slamming brakes is stored and transformed into an electrical charge, ready to jolt any pesky pup peeing on the tyre.

Hans Zoff, the man behind the Canine Repellent Alloy Protection system, said 'research shows that most BMW customers love to keep their cars clean - but dog fouling is a constant irritant.'

But Lola Forpi, from campaign group Put Animals First said, 'All motorists must expect to go through the odd puddle here and there. As well as going for a drive, we'd recommend owners regularly go for "walkies" as well if they want to have a very relieved pet.'
