OYEFLY Handheld Dog Repellent Trainer, 3 in 1 Anti Barking Device with LED Flashlight, Ultrasonic Dog Deterrent and Bark Stopper Dog Trainer Devices - Training Tool/Stop Barking (Yellow)

I chose the yellow, now when my dog see's it she knows I'm not pleased, I used the repellent trainer only twice so now all I have to do is put the flash light on and she's as good as gold. On walks if other dogs are aggressive or bark at us the dog hears it but not the owner, brilliant. thank you

Made absolutely no difference to my French/Pug cross dog. He continues to bark and is absolutely unfazed by the noise this emits. Bearing in mind he has French bulldog ears, vertical and constantly alert to every tiny noise, my thought process is that he would hear it from 100 yards away, but even right next to him he may sometimes look in my direction for a millisecond then continue to bark at blowing leaves/cars pulling up/ the postman/ everything else. Rated one star on this basis and my experience. Might work for other breeds.

My dog is very vocal and barks a lot . He gets very excited when visitors come and jumps up. Since having the trainer I’ve only used it on the middle setting a couple of times . When he sees the trainer in my hand he stops straight away with no need to press the button.

This is a handy gadget, it does stop my dog from barking.I didn't think it was value for money, but it works well.

Bought this as a barking deterrent for a dog that enjoys barking for attention. The device just caused my dog to bark at it. She did not seem to find the sound annoying in the slightest and whilst she showed mild interest for the first few days by barking at the device, over time she became so uninterested in the device that she did not even appear to notice when it was being used. Do not bother.

This has worked wonders on my dog. After two or three uses he got the hang of it and now stops barking at the sight of it. I have tried many other devices but this really works.

Does not seem to work on dogs, mine were barking still 😭😭

Not sure about this..I think the dogs are distracted by the light not the ultra sonic sound...depends on there mood as to weather they listen
