My neighbours advised my young terrier dog was barking late in the day before I was arriving home. I searched the internet for dog barking solutions and found dogs online. Information and options were helpful and addressed concerns with ensuring no harm to pets. Ordered the dog barking collar which vibrates as a deterrent. Delivered in a short time. Best of all the collar works, and my dog does not mind when I put it on in the morning. I’m using it as a training tool, so not turning collar on every day. Collar is adjustable to fit a small dog. Recharges within 30 mins, every 2nd day. Would recommend the vibrating collar.
