I first heard about this product when my son was living in Phuket, Thailand. He rode a motorbike, which was a popular way of getting about there and was troubled by packs of stray dogs, which roamed about and chased his bicycle. This was particularly distressing while after visiting friends, he could see the dogs waiting outside the house! He asked me to send him a Dog Dazer. Naturally fearful for my son, I rushed to comply with his request.
Here is how it works : The pocket-sized Dazer works by emitting ultrasonic sound bursts which can help to prevent the approach of unwanted dogs at distances of up to 5 metres (15ft). The high frequency sound bursts are inaudible to humans but are clearly heard and disliked by dogs.
This solved the problem for my son, and caused no harm to the dogs and prevented them from potentially harming him!
Even in the UK the Dog Dazer is very useful. The problem is often not with the dogs, but with their owners. Some owners even use their dogs as weapons or symbols of aggression! Dogs that are walking without a lead or even on an extended lead are a potential threat to walkers. I only recently read a report by a member of a Neighbourhood website about an owner, who had boasted that his dog, not on a lead had once bitten off the ear of another dog! This upset her young daughter, who was training her puppy which had approached the dog.
Once a large dog came and stood behind me on a footpath, with its nose pressed against my leg. I stood still and waited for the bite to my calf, which fortunately never came! Perhaps too late by then to use the Dog Dazer!
