Everything was going great. Rach had a big pot of chili cooking on the stove, I was sitting in front of my big screen TV, favorite adult beverage in hand, enjoying the afternoon when disaster struck.

Tom Brady, last year’s league MVP, arguably one of the best players to ever suit up, the quarterback for the mighty New England Patriots went down with a season ending knee injury. As depression set in I decided that I couldn’t let it effect me. I had to be pro-active about this and decided to take my dogs for a hike in the woods.

As I was walking with my dogs I thought about how important it is for our dogs to get regular exercise and activity. A lot of behavior problems are exercise problems. Many of the dogs that I see are not suffering from a behavior problem; they simply have too much pent-up energy and need exercise.

In this article you’ll learn the two forms of exercise that all dogs need. It’s important to understand that a lot of behavior problems stem from the dog having too much pent-up energy. Young dogs (4 to 14 months) have an unlimited amount of energy. In today’s society, a lot of dogs spend long hours by themselves. A lot of dogs are left in crates or in the house while their owners are at work. Day after day the dog waits around to do something. This pent-up energy builds and manifests itself into a behavior problem.

No amount of training can overcome an exercise problem.

The first step to overcoming your dog’s behavior problems is to physically exercise your dog. A lot of dogs spend a lot of time by themselves waiting for us to do something with them. Today there are many more resources for dogs than ever before. One of the best activities you can do with your dog is dog daycare. Dog daycare allows your dog to spend the day playing with other dog-friendly dogs. If a dog daycare is not right for your dog, a dog walker may be the answer.

Give your dog some mental exercise. Mental activities include: obedience training, tricks, agility, flyball and tracking. Mental activities are extremely important for your dog. I have seen very active, hyper dogs lie down and take a nap after a 10- to 15-minute obedience session.

The activities listed above are done with the owner. When you leave your dog alone, two of my favorite toys to leave with the dog are Buster Cubes and Kong toys. A Buster Cube is a hard plastic cube that has some compartments inside. You can pour some kibble into the cube and shake it up. When you put it on the ground your dog will smell the food in the cube and start to paw at it. Some of the kibble will drop out of the cube and this is what will keep your dog interested in the cube. I have seen dogs play with their Buster Cube for as long as an hour. It’s a great toy to leave with your dog when you have to be away for long periods.

Another great toy for your dog is the Kong toy. Kong toys are very popular and they make great toys because they are indestructible and are hollow which allows you to stuff the toy. Kong toys can be stuffed with peanut butter or cream cheese. You can also pack in a few biscuits. Once the Kong toy is stuffed you can leave a few around the house for your dog and keep her occupied for long periods.

Once your dog is getting enough physical and mental exercise you’ll see big changes in your dog’s behavior. A very popular and useful saying among dog trainers is: "The only good dog is a tired dog."
