If you have a puppy, its teeth are like needles. It hurts to bite, and it will break the skin. When the dog grows up, it will not be so sharp. You can only stop him from biting you.
The way is, when it bites you, you flick its nose with your hand and let it know that it hurts with a little force, so that it can't bite you. After repeated times, it will know that the dog won't know until you punish it when it does something wrong, so when it bites you, flick its nose. In addition, the grinding bar is not used to grind the dog's teeth. Don't try to smooth it with this.
Canine tooth:
Canine teeth, mammals and mammals-like animals, fangs between upper and lower incisors and molars. Mammalian teeth are differentiated, and scientists call them incisors, canine teeth and buccal teeth (including premolars and molars) according to their different shapes and functions. Canine teeth are tapered fangs located between incisors and molars. Carnivores have well-developed canine teeth, while some herbivores do not have such teeth. The main purpose is to tear food, which is what we call fangs.
