How old does a groundhog start to become aggressive A groundhog starts to become aggressive when it is eight months old, because before eight months, the groundhog is relatively young and will feel new to the things around him. After the dog is eight months old, the dog will be familiar with the surroundings and will have its own ideas and thus become aggressive. When the groundhog becomes aggressive, it is important to give more guidance to the groundhog so that the groundhog can play a good role in life, so training the groundhog’s guts is very important and will increase the groundhog’s self-confidence. After the dog has become bold, you can constantly tease the dog to make the dog’s emotions stronger, and when guiding the dog, it is recommended that the owner of the dog pretend to be very afraid, so that the dog becomes more majestic.
