Before getting this collar we had being reported to the council because our little puppy was barking too much at nights so when we took him to get his needles the vet recommended yous as one of the best brands, so I went home and decided I would go just with the hire to start with and it worked straight away!! It was like a miracle, it was like heaven on earth!! And just a week later he doesn’t even need to wear and if he starts to make a sound he knows that when we show it to him he’s not to bark or else we’ll put it on him again. If you’re wondering if it will work or not or if you are on the fence about it, don’t be! Because it truly does work wonders!
