Lang Qing may bite people if he has developed a bad habit of biting since he was a child, or if he is accidentally infected with rabies, or if he is in the period of teeth replacement. If the wolf is 4-8 months old, it is likely to be in the tooth replacement period. The owner can buy a teething stick or dog chew to let it grind its teeth. And training should start after the dog is 3 months old to avoid developing bad habits. However, if the wolf bites people and is also afraid of light, water, etc., it is likely to be infected with rabies. At this time, the owner needs to take the dog to the pet hospital for treatment in time.
