While the jury is still out on whether dogs use their sense of sight more than smell, it is pretty ridiculous to let Fido wear this LED Lighted Dog Collar when taking him for an early morning/night walk. After all, if he’s leashed to you, won’t you be the one carrying a torch instead? Unless you don’t mind letting Fido loose to do his own thing, which he probably won’t need the light at all since he’ll be too busy sniffing the area instead of relying on visual cues like us humans do. I would like to have full control of where my flashlight is pointed at, thank you very much, and would not want Fido to do the carrying for me. Still, if you want to bring home the LED Lighted Dog Collar, feel free to part with $40.
