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)

Não, porque o aparelho não faz o que ele promete. Não chega nem perto...

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.

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.

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

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.
