Research indicates that dogs often are good companions for people who exercise and that is certainly true in the greater Austin area. Dogs of every size, color and variety often frequent area hike and bike trails on outings with owners and families. Not all dogs are with runners, but there are plenty of people who train on the trails and many of them bring their best buddies along.

Veterinarian Stephanie Swanzy, DVM, of Anderson Mill Animal Clinic is a competitive runner who has participated in two marathons, including last weekend's White Rock Marathon in Dallas, and a smatterings of smaller races for about eight years. She runs often on various trails throughout Central Texas. Like others, she has been struck by the increasing number of dogs who accompany their owners.

"I see lots of people with various types of dogs on the trails," laughs Stephanie. "You can see anything from small toy breeds to big giant breeds. Not all the dogs are running, but many are. One that recently caught my eye was a little pug running as fast as he could alongside his owner. He seemed like he was having a good time."

Generally exercise is good for pets in the same way it is good for humans. It promotes strong hearts and lungs, good muscle tone, strength and stamina. But if you are planning to begin running with your best buddy, it's a good idea to think about your dog's comfort and safety. Stephanie offers some professional advice to make running with your dog a good experience for you both.

• Consult your pet's veterinarian . "Just like humans, dogs need a physical examination before they begin a running routine," she says. A check-up can identify any conditions or medical reasons that might impact how long or how far your dog should run or whether the animal should run at all.
  
  
• Pick the right pet. If you are a serious runner, make sure your dog is a breed that enjoys running and is physically capable of the challenge. Stephanie says: "Some dog breeds will not be able to exercise very much or for very long because of their particular body shapes and physiology. For example, a Boxer will have more limitations than a German Shepherd. It just makes sense that a tiny dog can't run as far or as fast as a larger one."
  
  
• Devise a training routine . "Just like you might train for a race, your dog needs to train for running," adds Stephanie. "Let your dog set the pace as you start out and work up to longer distances and times. Pay a lot of attention to your dog and learn to recognize when he is telling you 'hey, I'm getting a little pooped here.'"
  
  
• Consider the physical condition of your dog . "Even if there are no medical challenges, if your dog is overweight, he may tire more easily or have pain in his joints when he runs. Overweight dogs are also at greater risk for heat stroke."
  
  
• Be conscious of heat and humidity. "Dogs can suffer from heatstroke just like you and they lose body heat more slowly than humans. Heat loss is mainly through the mouth (panting) with some loss through the foot pads. Watch for signs of distress and stop if you see them, even if you haven't been running long," says Stephanie.
  
  
• Be alert for serious symptoms . "Most dogs will try to keep going, but if they begin to lie down, won't go any further and are having difficulty breathing, stop immediately."
  
  
• Water your dog . "Carry enough water for yourself and perhaps a collapsible bowl in your pack," she suggests. "If you are running longer distances, more than a mile or so, keeping your dog hydrated is important. If you run on area hike and bike trails, you'll find fountains along the way and many of them have low water fountains especially for dogs. But it's still a good idea to plan ahead," she advises.
  
  
• Keep an eye peeled for injuries . "One of the most common injuries to watch for is wear on the pads. Sometime on really hot pavement, pads can wear to the point of blistering. Remember that your dog doesn't have shoes. Also, just like humans they can injure joints and ligaments that may cause limping and pain."
  
  
• Run reasonable distances . "I wouldn't run with a dog more than three to five miles. Don't consider a marathon. The 26.2 mile course is punishing for humans even after months of training. Pay attention to your dog and work up to a distance that is comfortable and still fun. All dogs are different. If you have a young border collie with boundless energy, the two of you may be able to run further." The smaller the dog, the shorter the distance they can run. Dachshunds, Chihuahuas and other small breeds may only be able to go a short distance.
  
  
• Use a leash . "When you run with your dog, I'm a big advocate of leashes," says Stephanie. "It will help you prevent accidents with cars, bicycles and pedestrians." Remember to keep the leash at a length at which you can control the animal but no longer. If you both act as two runners on the trail instead of a unit, it will be a challenge for some runners to pass.
  
  
• Use reflective material at night. "As days get shorter in the fall and winter, use reflective tape on your dog's collar or a blinking light. Drivers may not be able to see your dog even if they can see you."
  
  
• Pick up after your pet as it's the law . City of Austin Ordinance states that the owner of a dog can be fined up to $500 for failure to remove animal waste left on public or private property. Recycle grocery store bags or pick up a few on the trail. The City of Austin provides animal waste bags at various spots on the Lady Bird Lake Trail.
  
  

"Many dogs love to run and they are reliable running buddies who are always ready to go. Just make sure you use good common sense about their health and well being and they can be your best companion while you train for a race," adds Stephanie.
