My dog always pulled every time i tock him for a walk, and everyone that had tryed to walk him said that they did not want to walk him no more, i had had it with the dog, untill i spoke to a friend and she told me about the halti dog training head collar, so i looked it up and bought one, i put it on wich was easy, then i tock my dog for a walk, and he did not pull once, walking him was so so easy i loved it, i would have to say that halti training collar is the best thing i had spent money on in a very long time.
excellent.
