Studies conducted in the United States indicate that approximately 1 in 5 adult dogs shows clinical signs of osteoarthritis, one of the leading causes of pain and loss of mobility over a dog’s lifetime. When signs such as stiffness, difficulty moving, and reduced activity are also considered, this number increases significantly over the years— especially in middle-aged and senior dogs.
This is not a small figure. And it becomes even more concerning when we understand that mobility problems affect more than just movement. They also impact behavior, daily routine, and overall quality of life—for both the dog and the family who lives with them.
When we look at the data compiled by the Orthopedic Foundation for Animals, one thing becomes clear: some breeds simply carry a heavier burden when it comes to joint health. In certain cases, joint alterations appear two, three, or even four times more frequently than in the average American dog population. Not by chance, but because of how these bodies are built.
It’s structure.
It’s genetics.
It’s how the body moves over time.
From that point on, understanding **which breeds are more prone to mobility problems—and why—**stops being a matter of curiosity and becomes a tool for better care.
What does it mean for a breed to be more prone to mobility problems?
It means that not all dogs start from the same place when it comes to joints and movement. Some breeds are built in a way that requires their bodies to handle more impact, more weight, or a less balanced distribution of load from an early age. This may be related to size, body proportions, joint alignment, or growth rate.
When we talk about predisposition, we are not talking about an inevitable outcome. We are talking about a different starting point. Dogs living very similar routines can experience the effects of time and physical stress in very different ways, simply because of the body structure they were born with.
That is why, when large-scale data—such as those compiled by the Orthopedic Foundation for Animals—are analyzed over the years, certain breeds appear far more frequently in joint-related statistics than others. Not by coincidence, but because specific conformations concentrate more wear over a lifetime. This is the pattern behind why some breeds stand out when the topic is mobility.
Large breeds: when rapid growth meets body weight
Large and giant breeds appear frequently in records related to dysplasia and joint wear. Despite their differences, they share a common factor: the combination of size, rapid growth, and constant load on the joints.
Labrador Retrievers and Golden Retrievers, two of the most popular breeds in the United States, illustrate this well. Fast growth and large body size place significant demands on the joints from an early age— even in dogs that are well cared for and physically active.
In Labradors, one additional factor plays a major role: excess weight. The American Veterinary Medical Association recognizes obesity as one of the main factors that worsen joint problems in dogs, especially in large breeds.
In German Shepherds, the challenge is often biomechanical. In many American bloodlines, increased angulation of the hind limbs alters how weight is distributed during movement. Joint wear develops not from excessive exercise, but from the daily repetition of an unbalanced movement pattern.
Breeds such as the Bernese Mountain Dog and the Great Dane also face the structural limits of their own size. High body weight places constant stress on joints that are still maturing during the growth phase.
Small breeds are also part of the risk group
The idea that small dogs are naturally protected when it comes to mobility does not hold up when we look at the data.
Pugs appear in historical OFA data with one of the highest proportions of hip dysplasia among evaluated breeds. Despite their small size, their compact build and unfavorable joint alignment compromise stability over time.
French Bulldogs—extremely popular in the United States—combine short limbs, a sensitive spine, and low tolerance for repetitive impact. In a typical routine involving hard floors, stairs, and frequent jumping, joint wear tends to appear early.
In Dachshunds, the main concern lies in the spine. The relationship between a long torso and short legs increases the risk of intervertebral disc disease, directly affecting mobility and comfort.
In breeds such as Chihuahuas, conditions like patellar luxation are relatively common, largely due to the natural instability of the knee joint.
What can tutors do knowing this predisposition?
Having a higher predisposition does not, by itself, define how this dog’s life will unfold. For those living with breeds like these, this information should not create fear, but awareness.
Knowing that a dog belongs to a higher-risk breed makes it possible to act before discomfort appears. Low-impact, controlled-intensity exercise, such as regular walks at a moderate pace, helps maintain muscle strength without overloading the joints.
Body weight control is one of the most important factors in reducing joint stress over time—a point consistently reinforced by American veterinary organizations.
In addition, many tutors choose joint-specific nutritional support, using ingredients traditionally included in veterinary routines, such as glucosamine and chondroitin, as part of ongoing care. This type of support does not replace clinical follow-up, but it can help sustain joint health throughout life, especially in predisposed breeds.
The care that supports mobility over a lifetime
Mobility problems rarely appear overnight. They develop gradually— just as proper care can be built over time.
A dog from a predisposed breed is not destined to live with pain or limitation. When genetics, routine, weight control, appropriate activity, and supportive care work together, many dogs enjoy years of comfort, independence, and quality of life.
Understanding the reality of the breed is the first step. But caring for the body in the right way is what truly makes the difference.
