change the leds to red and find a way to determine with a sensor when the dog is about to attack (growl detector maybe?), and you have a modern-day hound of the baskervilles!

Since the LEDs are blue, does that mean Sunshine is a police dog?

I use something simular from £-land. I have a german shepard and need to use 2 as they are used for children arm’s

£2 is not bad and bat lasts 4-5 month’s CR32

Then im left with 12 led’s to play with

In many places you cannot carry blue lights on vehicles since they are reserved for the cops, I wonder if police dogs also have the exclusive right to blue led collars :)

But ‘link’ is right, you can buy collar attached lights and lighted collars in every pet store for quite a while already, years.
in fact I’ve seen light to attach to collars in supermarkets even.

Fun. After seeing this, I’m surprised my submission never made it through:

Maybe its because I’m lame and don’t have a video. :)

@Whatnot

Imagine a dog chasing a car down the road, but now it’s wearing red/blue flashing LED’s.

I’m pretty sure it will have a better chance of actually catching the car.

what a sexy dog

@ChalkBored that will freak out anybody, especially if they just smoked some weed :)

@Whatnot

I’ve seen those collars before, they are not super bright, plus they don’t do cool patterns like the one I made :-)
