Review on Rechargeable Improved Visibility Flashing Water Resistant by Laura Church

I use this for my big boy who is 64lbs and the family chihuahua who is around 10lbs. I cut both collars to match! I read the reviews and people seemed confused about how to cut it and you just cut the wires between the bulbs! But you also cut the rubber. First, put on the collar and measure around the dog's neck. Pick a spot between the light, cut it out and bam! Good size! In the photo I have what I cut off next to the lighted collar. Make sure it's turned off when you cut it! And take off the end of the white bar, because that's what you need to put on the new end. Also, do not cut off the white end with the power button and the side of the charger. Cut off the little white side.
