Chewing on plastic can be a very satisfying activity for dogs, and a difficult one to stop. Dogs chew on many materials for a variety of different reasons. Chewing on plastic could be something that occurs out of boredom, a need to destroy and let out aggression, or simply because the dog doesn’t know better. Chewing on plastic can be detrimental to a dog’s health, however, so it is an action that should be stopped as quickly as possible.
Plastic can develop sharp edges when chewed, which can cut a dog’s mouth and gums. Harder plastics can also chip a dog’s teeth. When ingested, pieces of plastic can be harmful to the digestive system, and painful when thrown up or defecated. One easy way to stop a dog from chewing plastic is to get rid of plastic items before your dog has a chance to chew on them at all. Things like plastic bottles, bags and containers should always be kept out of a dog’s reach.
You should also make sure that your dog has enough other play toys to keep it busy and satisfied throughout the day. Present your dog with a variety of bones and hard toys that will satisfy the urge to chew. Your dog should also be exercised regularly so that there is a productive release of energy and aggression is not allowed to build up, which often results in chewing.
