The molar stick is a protective tool for the dog's teeth. Dogs are prone to bad breath. Part of the reason is that the calculus of the dog's teeth has become the best breeding ground for bacteria in the dog's mouth. In the process of chewing dog chews, dogs can polish off the calculus on their teeth as much as possible to avoid periodontal disease and reduce bad breath. The molar stick is an important tool for emotional communication between the owner and the dog. Under the proper guidance, the dog does what the owner wants to do. Giving a molar stick to the dog can make the dog familiar with the instructions faster. Although the molar stick is a good thing, it should not be fed blindly. Do not give cheap and inferior molar sticks to dogs. Old dogs with bad teeth should not be fed molar sticks casually. The size of the molar stick should also be in line with the size of the dog's mouth, and the consumption should not exceed 2 a day.
