Barking is a natural way for dogs to communicate. Their “voice” might not be pleasant to our ears, but a dog’s bark can have many different meanings – let’s play, I’m lonely, back off, frustration, etc. Dogs that excessively bark while owners are gone are often frustrated. To help alleviate this, be sure to work with your dog daily. Walk or run your dog in the morning – wear him out – so he is tired throughout the day. It is a good idea to have three toys that your dog can play with while you are away. If barking is excessive and very difficult to curb, bark limiter collars can be effective tools. Always consult with a professional before using one for the first time.
