Input: They worked well for one month but with a puppy that bites things they probably aren't made to withstand him chewing and chewing. Also my dog's mouth is too small so it was kind of painful she didn't like them as much because her teeth were trying to pop out from behind the bandanas.
Output:
Good Review
