Yes, interactive dog toys do work. The idea behind an interactive toy for dogs is that the toy needs to keep the dog engaged. That means your pet dog needs to actively participate when playing with it. They are not like plush toys that are only there to comfort your dog. Interactive toys will respond to your pet when they play with them. As a result, the dog will choose to spend more time with these interactive toys over the regular ones. Thanks to mental as well as physical stimulation from these interactive toys, your dog will feel less anxious and bored, and will not do anything naughty like tearing up paper or your cushions.
