Factors to Consider

Before you take your furry friend out for a run, there are several factors you should consider to ensure their safety and well-being. These factors include your dog’s breed and size, health and fitness level, growth and bone development, and consulting with a veterinarian.

Breed and Size Considerations

Different breeds have different exercise needs and capabilities, so it’s important to consider your dog’s breed and size when determining if they are ready to start running.

Small and Toy Breeds

Small and toy breeds generally have less endurance and are prone to fatigue more quickly. It’s important to start slow with these breeds and gradually increase their exercise level. Shorter distances and slower paces are recommended to prevent overexertion.

Medium and Large Breeds

Medium and large breeds have a higher energy level and endurance capacity compared to smaller breeds. However, it’s still important to start slow and gradually increase their exercise intensity. These breeds can handle longer distances and faster paces, but it’s important to monitor their fatigue levels to prevent injuries.

Giant Breeds

Giant breeds, such as Great Danes or Saint Bernards, have specific considerations due to their size and weight. Their growth plates take longer to close, which means that high-impact activities like running should be postponed until they reach their full skeletal maturity, typically around 18-24 months of age. Prior to that, it is best to engage in low-impact exercises like swimming or walking to promote healthy growth and bone development.

Growth and Bone Development

When it comes to running, a dog’s growth and bone development play a crucial role in determining their readiness. It’s important to consider these factors to prevent any potential damage or long-term consequences.

Puppyhood and Growth Plates

Puppies have developing growth plates, which are areas of cartilage at the ends of their bones. These growth plates are responsible for bone growth and, therefore, are more vulnerable to injury. Intense or prolonged exercise, such as running, can put excessive stress on these growth plates and lead to developmental issues. That’s why it’s crucial to wait until a puppy’s growth plates have closed before introducing them to running.

Varying Growth Rates

Different breeds have different growth rates, and it’s essential to take these variations into account. Smaller breeds tend to mature faster than larger breeds. Researching your specific breed and consulting with a veterinarian can help you determine the appropriate age at which to start running with your dog.

Bone Maturation and Strength

A dog’s bones continue to develop and strengthen as they grow. Running or engaging in high-impact activities before their bones have fully matured can increase the risk of injuries, such as stress fractures or joint problems. Waiting until a dog’s bones have reached their full maturity ensures their skeletal structure is strong enough to handle the demands of running.

Signs of Readiness

While age and breed considerations are important, it’s equally important to look for signs of readiness in your dog. These signs can indicate their physical and mental preparedness to start a running routine.

Physical Signs of Readiness

Physical signs of readiness include good muscle tone, healthy weight, and overall fitness level. If your dog is lean and has no existing health issues, they are more likely to handle the physical demands of running. However, it’s important to note that physical appearance alone should not be the sole indicator of readiness. Consulting with a veterinarian is always recommended before starting a new exercise routine.

Behavioral Signs of Readiness

Behavioral signs of readiness include enthusiasm for exercise, eagerness to explore, and a sustained interest in activities that require physical exertion. If your dog is always eager to go for walks or play fetch, it might be a good indication that they are ready for a more intense exercise like running. However, it’s important to introduce running gradually to evaluate their endurance and comfort levels.

Starting Slow and Gradual

Once you have determined that your dog is physically and mentally ready for running, it’s crucial to start slow and gradually increase their exercise routine. This approach helps to prevent injuries and allows their body to adapt to the new demands of running.

Begin with Short Distances

Start by taking your dog for short runs, gradually increasing the distance over time. This allows their muscles and cardiovascular system to adjust to the increased workload. For small breeds, this may mean starting with just a few minutes of running, while larger breeds can handle slightly longer distances.

Monitor for Fatigue or Discomfort

During and after each run, monitor your dog for signs of fatigue or discomfort. Heavy panting, excessive drooling, limping, or reluctance to continue running may indicate that they have reached their limit or are experiencing pain. If you notice any of these signs, it’s essential to slow down, take a break, and consult with a veterinarian if needed.

Increase Distance and Intensity Over Time

As your dog becomes more comfortable with running, you can gradually increase the distance and intensity. Just like humans, dogs need time to build their endurance and strength. Pushing them too hard or too soon can lead to injuries, so always pay attention to their cues and adjust the pace accordingly.

Age Recommendations

The optimal age for a dog to start running varies depending on their breed, size, and individual development. Here are some general age recommendations to consider:

6 Months – 1 Year

For small to medium-sized breeds, the age of six months is typically a good starting point for introducing them to short, low-intensity runs. However, it’s important to remember that individual dogs may vary in their development, so consulting with a veterinarian is essential.

1 – 2 Years

For medium to large breeds, waiting until they are one to two years old is generally recommended. This allows their bones and joints to fully mature and reduces the risk of potential growth plate injuries. Again, it’s important to consult with a veterinarian to determine the best age for your specific dog.

2+ Years

Giant breeds, such as Great Danes or Saint Bernards, often require an extended period of time before they are ready to start running. Waiting until they are fully mature, which is usually around two years of age or older, ensures their bones and joints have developed sufficiently to handle the physical demands of running.

Running Guidelines

Once your dog is ready to start running, it’s important to follow certain guidelines to ensure their safety and well-being.

Use Proper Equipment

Investing in proper running equipment is crucial for both you and your dog. A well-fitted harness can help distribute the pulling force evenly, reducing strain on your dog’s neck. You may also consider a hands-free leash or a waist belt to provide a more comfortable and secure running experience.

Choose Safe Routes

When choosing running routes, prioritize safety. Avoid roads with heavy traffic or uneven surfaces that could potentially cause injuries. Instead, opt for paths or trails that are designated for pedestrians and offer a clean and safe environment for both you and your dog.

Consider Weather Conditions

Consider the weather conditions before taking your dog for a run. Running in extreme heat or cold can be dangerous for your furry friend. On hot days, opt for early morning or late evening runs when temperatures are cooler, and be sure to bring water for both yourself and your dog. In colder weather, consider investing in protective gear like a doggy jacket to keep them warm.

Allow for Rest and Recovery

Rest and recovery are just as important for your dog as they are for you. Be mindful of their fatigue levels during and after each run. Taking regular rest days, offering them plenty of water, and providing a comfortable rest area ensures they have the time and environment needed to recover properly.

Alternatives to Running

While running can be a great way to exercise with your dog, it may not be suitable for every situation or every dog. Here are a few alternative activities that offer similar benefits:


Walking is a low-impact exercise that provides many of the same benefits as running. It allows dogs to explore their surroundings, burn energy, and bond with their owners. Plus, it’s a great way for you to get some exercise too!


Swimming is an excellent alternative for dogs of all ages and sizes. It provides a full-body workout while being gentle on the joints. Swimming helps build endurance, strengthens muscles, and can be a fun and refreshing activity for your dog.

Agility Training

Agility training involves navigating through obstacle courses and can be a mentally stimulating and physically challenging activity for dogs. It promotes coordination, balance, and endurance, making it a great alternative to running.
