Review on 🐶 Rechargeable Bark Collar - Adjustable Sensitivity & Intensity, Shockless & Harmless, Beep & Vibration, No Pain, Ideal for Small, Medium & Large Dogs by Donna Lawson

I have set this collar to the lowest setting of 1 and green. My dog started walking in circles looking at his butt trying to figure out where the sound/vibration was coming from. My other dog's bark activated it. He was completely angry and scared to be in the house. He is an 82 pound German Shepherd. He tried to climb onto the countertops and furniture and clung to me. He was shaking like a dog afraid of thunderstorms and fireworks, which isn't really the case. He finally fell asleep and luckily this morning he is much better. I hope the injury doesn't affect him in the future. I am returning the collar.
