Are you worried that you may have a bored dog? Dogs are energetic creatures with a deep desire to play and socialize. When they've been stagnant for too long, dogs get bored, and a bored dog is an unhappy one. Recognizing boredom in your dog is an important part of dog-parenthood, and playing games with your dog is a great way to reenergize him.

Create an Enriching Environment

Keeping animals stimulated is important, and no one recognizes the importance as much as zoos. Providing a stimulating environment at zoos is called "enrichment," and dogs need an enriching environment in their home, too.

The Smithsonian Conservation Biology Institute states, "Enrichment includes the design of stimulating and naturalistic enclosures, the housing of appropriate social groups in zoos, and the introduction of objects, sounds, smells or other stimuli in the animal's environment. Environmental enrichment is just as critical to zoo animal welfare as nutrition and veterinary medicine. At the National Zoo, enrichment is an integral part of the daily care of the species in our collection."

Do you introduce new stimuli to your dog? How about mixing up the games you play? Even active dogs can get bored if their routine becomes, well, too routine. Here are five signs your dog is bored, and a list of games you can play to reenergize him.

Signs of a bored dog, and games to keep him enriched and entertained

Increased Barking

If you've noticed your dog has been barking more frequently than normal, there's a good chance that you have a bored dog on your hands. Out-of-the-blue barking is one way a dog can get the attention of his pet parent, even if he doesn't appear to be barking at you. Think of it as a mild way of acting out.

Training is a great way to play with your dog. You might think that your dog won't like training, but that isn't true. Dogs enjoy being busy and having a job to do. Give your dog mini-missions. First, teach your dog how to stay. Next, while in the staying position, throw a toy and allow it to land. After waiting, let your dog out of the staying position, with whatever command you use ("okay" or "go"). Once he reaches the toy, have him deliver it back to you. Practice it over and over, and your bored dog will suddenly become a sleepy dog.

Increased Chewing

Bored dogs tend to become destructive. If your once-angelic pup is chewing your couch or shoes, or anything else for that matter, it's time to take action to stop the behavior before it becomes a regular issue.

Tug-of-war is a great game to play with a dog who loves to have something in his mouth. However, before playing any games that involve chewing or using a snout, make sure to train your dog what is okay to eat and what isn't.

Also, food-related games are great to play with chewers, as long as you're careful not to over feed your pet. There are many ways you use food to play with your dog. First, you could buy a puzzle feeder to make your dog work hard for his treats. Also, try hiding little pieces of kibble in one room and then letting your dog play detective. If he finds a treat, it's his to eat!

Circle Running

Has your dog suddenly started chasing his tail? Do you find him pacing the room in circular motions? A circle runner has a lot of energy to burn off.

Exercise is the best form of playing for a highly energetic dog. A game of Frisbee® or ball toss is a great game to play. Other ways to burn off energy are long walks or even brisk runs. As long as you're staying active, any games that require physical activity will work.
