Not at all. The device emits ultrasonic waves that simply make dogs uncomfortable, causing them to back off. It doesn’t cause any physical harm and is a safe, humane way to deter unwanted animal encounters.
It’s most effective on stray or untrained dogs. Pet dogs, especially those with their owners or those that are well-trained, may not respond as strongly. Also, very noisy environments can reduce its effectiveness.
The built-in 800mAh battery lasts for several days with normal use. It depends on how often you use the ultrasonic and flashlight features. The power indicator light helps you know when it's time to recharge.
I walk my dog in the evenings, and this device gives me peace of mind. It’s comforting knowing I have a way to handle any unexpected encounters with stray animals.
I use this on my morning jogs. It’s small, light, and actually works! I've already avoided a few situations with aggressive dogs thanks to it.
Love how straightforward it is. One button for sound, one for light. It fits right in my pocket and doesn’t weigh me down at all.
