My 6 months old puppy is eating the wood from furniture. Is it harmful ? How do I stop him from doing that ?

Hello. It shouldn’t considered normal if a dog chews or eats wood. It’s harmful if a wood splinters puncture or stuck in the oral or Gastrointestinal cavity. The reasons for this could be boredom/anxiety/stress. It can also be due to nutritional deficiency. Keep your pet engaged with chew toys or other exercises. Give a training. Discourage wood chewing using positive reinforcement and by giving treats.
