Why Fit Dogs Still Get Injured

POST CATEGORY

Other Categories

This past week I was reviewing fitness programs designed by students in our Elite K9 Athlete Program. As I worked through their assignments, I realized I was giving the same feedback over and over again.

Slow down.

Increase the difficulty of the exercises more gradually.

Pay attention not only to today's workout, but also to the overall workload across the week.

One of the biggest mistakes I see people make when designing a conditioning program is progressing their dogs too quickly. Sometimes that means increasing the difficulty of an exercise before the dog has mastered the basics. Other times it means increasing the overall workload too rapidly by adding more training days, longer sessions, or harder activities before the dog's body has had time to adapt.

For example, if a dog is currently exercising for 15 minutes twice a week, it wouldn't make sense to suddenly increase those sessions to 30 minutes while also adding three more training days. The body simply doesn't adapt that quickly.

As I was thinking about what to write and share today, I suddenly laughed at myself.

I had spent the week reminding my students to follow one of the most fundamental principles in exercise science...and then I went out and completely ignored it myself.

A Lesson Learned on Two Wheels

If you've been following my move to Norway, you know I recently bought a bicycle.

Although I had a bicycle back in Maine, I honestly hadn't ridden on a regular basis for at least a year or two. I was excited to finally have one again. I wanted to explore Oslo, ride along the coastline, and enjoy my new surroundings.

Within the first week of buying the bike, I went out for what I considered an easy 10-mile ride.

The following week I rode to my kayak club and ended up tackling a short—but fairly steep—bike path. I remember thinking it was a great workout.

It certainly was.

Unfortunately, my body wasn't quite ready for it.

Looking back, I realized I had broken just about every exercise science principle I teach.

Not only had I introduced a completely new activity after not cycling for years, but I also increased the intensity far too quickly by adding hill work. On top of that, I went from essentially no cycling at all to multiple rides during the same week.

The result was sore calf muscles, an extremely tight right gastrocnemius muscle, and waking up one morning with one of the worst muscle cramps I've had in years. Instead of continuing to enjoy my new bike, I had to back off my training and let my body recover.

It was a great reminder that enthusiasm doesn't change physiology.

Whether we're talking about people or dogs, the body still follows the same rules.

The Body Needs Time to Adapt

One of the things I love about exercise science is that the underlying principles are remarkably consistent. Whether we're talking about a human runner, a French Ring dog, an agility competitor, a sled dog, a detection dog, or a family pet beginning a conditioning program, muscles, tendons, ligaments, bones, and the cardiovascular system all need time to adapt to increasing demands.

When we gradually challenge the body and allow it sufficient time to recover, it responds by becoming stronger and more resilient.

When we ask too much, too soon, the body has a different way of responding.

Sometimes that response is subtle. A dog may seem a little stiff the next day or take longer than usual to recover after training. Other times we begin to see changes in movement, compensation patterns, declining performance, or injuries that appear to have come out of nowhere.

In reality, many of those injuries didn't happen overnight. They were simply the result of asking the body to progress faster than it was prepared to adapt.

Progressive Overload: Small Steps Lead to Big Improvements

One of the fundamental principles of exercise science is the Principle of Progressive Overload. Despite the name, this principle isn't about pushing the body to its limits every workout. Instead, it's about making small, planned increases in workload over time. Progressive overload might mean adding another repetition to an exercise, increasing the duration of a walk by a few minutes, introducing a slightly more challenging exercise, or adding another training session after your dog has adapted to their current schedule.

The important word is progressive.

As handlers, it's easy to become excited when our dogs are doing well. They seem stronger, they're enthusiastic, and they look like they can handle more. The temptation is to increase several things at once.

I've seen this happen in just about every canine sport.

An agility team starts preparing for trial season, so practice sessions become longer while additional jump sequences are added. A detection team begins preparing for certification and suddenly starts doing longer searches in more challenging environments several days in a row.

Spring finally arrives, and a dog that has spent most of the winter walking around the neighborhood is suddenly hiking several hours every weekend.

The body may eventually adapt to these new demands, but only if we introduce them gradually.

Fitness is Specific

Another concept I frequently teach is the SAID Principle, which stands for Specific Adaptation to Imposed Demands.

In simple terms, the body adapts to the specific work we ask it to do. This is exactly where I made my mistake with cycling.

Running five or six days a week didn't automatically prepare my body for climbing hills on a bicycle. Although both are excellent forms of cardiovascular exercise, they challenge the body in different ways.

The same concept applies to our dogs.

A dog that is conditioned for endurance running isn't automatically prepared for repetitive jumping.

A detection dog that spends hours searching buildings isn't necessarily conditioned for scrambling over unstable rubble. Additionally, a dog that regularly hikes on flat terrain isn't immediately prepared for steep mountain trails.

Fitness isn't a single quality. It is specific to the demands placed upon the body.

Whenever we introduce a new activity, terrain, or exercise, we should expect that the body will need time to adapt.

Don't Change Everything at Once

One of the easiest ways to safely progress your dog's training is to remember the FITT Principle.

FITT simply refers to four variables within any exercise program:

  • Frequency - how often your dog trains

  • Intensity - how difficult the activity is

  • Time - how long the activity lasts

  • Type - the specific activity you're asking your dog to perform

Any one of these variables can be adjusted to increase the workload. The mistake is changing several of them at once.

Looking back at my own cycling adventure, I introduced a new activity, increased the duration, rode more frequently, and added hills... all within the same week!

Not surprisingly, my body objected.

When you're planning your own dog's conditioning program, try changing just one variable before moving on to another. It gives the body time to adapt and also allows you to evaluate how your dog responds before making additional changes.

Applying These Principles to Your Own Dog

The next time you're tempted to make your dog's workout a little harder, take a moment to step back and look at the bigger picture.

Ask yourself:

  • Has my dog truly adapted to their current workload?

  • Am I increasing more than one training variable at a time?

  • Is this a new type of activity that requires a period of adaptation?

  • Have I given my dog enough time to recover before asking for more?

These questions are just as important for sport and working dogs as they are for family pets. Whether your goal is to improve performance, reduce the risk of injury, or simply help your dog stay active as they age, consistent and thoughtful progression will always outperform doing too much too soon.

Final Thoughts

My calf is doing much better now, and I'm slowly getting back on the bike. This time, however, I'll be following the same advice I give my students.

I'll progress gradually.

I'll respect the adaptation process.

And I won't try to change everything at once.

As handlers, we're often excited because we see what our dogs are capable of doing. The challenge isn't holding them back. The challenge is giving their bodies enough time to catch up.

The irony isn't lost on me that I needed my own reminder.

Fortunately, it wasn't a serious injury. It simply reinforced something I've believed for years: the best conditioning programs aren't built by making big jumps. They're built through consistency, patience, and small, intentional steps that allow the body to adapt over time.
