When dropped these spook dogs, it's an easy way to cause reactivity and fear in your pet. They're very effective at what they're made for.

There are far better and safer options out there, backed up by scientific evidence to help train your dog in a way that benefits you both, rather than scaring them if they make a mistake.

Please don't try to train your dog by frightening it. There are much kinder - and more effective - ways. Zooplus - please do better and remove this aversive tool.

I have an 8 month collie who, after owning many dogs all my life, I was about to rehome. Her main problem was aggression towards other dogs. She started chewing an armchair and I threw them on the ground next to her. She hated the noise. Bingo I got a reaction. Within two weeks I have fallen in love with her, she is almost perfect. We are both relaxed even around other dogs. A little rattle and she stops immediately and listens to me. Literally amazing. Soon I won’t even need them.

I have never been able to use clicker training because of hand weakness. These training discs are similar but have the opposite function. If the discs are rattled the dog does NOT get the treat. It makes a distinctive noise and gets the dog's attention even when it is excited by a running cat :-)

These are effective IF used correctly As a behaviourist with many years experience they must be thrown on the ground once only, while giving a low verbal 'NO ' . Timimg is crucial Use them when it is thinking about doing something e.g barking ,jumping ect Never throw them when dog is already adrenalised It will make them worse.
