Sometimes, your playful pooch might give a little nip to your hand or something else that shouldn't be bitten. To stop bad biting behaviors, you should attempt to redirect your dog's attention to an appropriate chew toy. You can do this by placing the toy in their mouth and praising them, causing your canine companion to associate chewing on the chew toy with positive emotions. Another step you can take to redirect biting behavior is to use biting deterrent spray. The spray can be homemade or store-bought. Just make sure that the ingredients won't make your puppy's tummy sick! Which of the following terms identifies the author's tone in the passage?
