For training problem behaviors! ・This is an anti-chew spray made with ingredients that are safe even if your dog licks it. ・Prevents chewing, nipping, biting of paws, and excessive licking of fur with a bittering agent that dogs dislike. ・Unscented, so it won't interfere with toilet training even if sprayed on toilet sheets to prevent chewing. Please refer to the fourth photo for the remaining amount. Thank you for looking.
