[Dog Joint Care] Do Dogs get Joint Pain on Rainy Days? Is it “Rheumatism” or Something Else?

During Hong Kong’s rainy summer, you may hear people say, “My joints hurt when it rains.” But can dogs experience the same thing? If your dog walks more slowly, avoids walks or seems stiff on rainy days, does it mean they have “rheumatism”?

Not exactly. “Rheumatism” is not a specific veterinary diagnosis. While weather changes may make existing joint problems more noticeable, recurring stiffness or reduced mobility should not simply be blamed on the rain.

Can Rainy Weather Really Cause Joint Pain in Dogs?

“Rheumatism” is not a specific veterinary diagnosis. Dogs with existing joint problems may show more stiffness or reduced activity when the weather changes. However, if your dog simply does not want to go outside occasionally when it rains, this does not necessarily mean they have a joint problem. 

On the other hand, if you notice the following signs repeatedly, do not simply assume that the weather is to blame:

• Moving more slowly when getting up or lying down
• Reluctance to jump up or down
• Difficulty going up or down stairs
• Reluctance to walk or play
• Stiffness or limping when walking
• Changes in their usual activity patterns

Rainy weather does not necessarily mean that your dog has “rheumatism”. However, changes in weather may make previously subtle joint problems more noticeable.

What Are Some Common Joint Problems in Dogs?

Joint problems can affect dogs of different ages and breeds. They are not only something that owners of senior dogs need to be aware of.

What Can Increase the Risk of Joint Problems in Dogs?

Age

As dogs get older, the risk of degenerative joint problems may increase. However, “slowing down because of age” does not mean that every change in mobility is a normal part of ageing.

If a senior dog suddenly becomes reluctant to walk, jump or use stairs, it is worth considering whether an underlying joint or other health problem may be involved.

Breed and Genetics

Different breeds may have different risks of developing joint conditions. For example, some large breeds are more prone to hip or elbow problems, while patellar luxation is more commonly seen in some small breeds.

Excess Weight

Body weight is an important factor in maintaining joint health.

Being overweight increases the load placed on a dog's joints during everyday movement. Maintaining a healthy weight is therefore not only about appearance, but also an important part of long-term joint care.

Inappropriate Exercise

How Can You Care for Your Dog's Joints During the Rainy Season?

1. Maintain Appropriate Exercise

Rain does not mean that dogs should stop exercising completely. Depending on the weather and your dog's physical condition, adjust the timing and intensity of walks and other activities.

If your dog already has a joint problem, avoid sudden increases in exercise and follow your veterinarian's recommendations for suitable activities.

2. Be Careful on Slippery Surfaces

Wet surfaces can become slippery, making it easier for dogs to lose their balance when running, stopping suddenly or turning.

At home, you can also use non-slip mats in areas where your dog frequently walks, sleeps or gets up to reduce the risk of slipping.

3. Reduce Unnecessary Jumping

If your dog is already showing signs of joint discomfort, try to reduce jumping on and off sofas, beds and car seats.

Depending on your dog's mobility, you may also consider using a pet ramp or steps to reduce the impact placed on their joints.

4. Maintain a Healthy Weight

Weight management is an important part of long-term joint care.

If your dog is overweight, speak with your veterinarian about an appropriate weight management plan, including daily calorie intake, food choices and exercise.

Can Dog Joint Care Start with Diet and Nutrition?

In addition to weight management and appropriate exercise, nutrition can also form part of an overall joint management plan for dogs.

Frequently Asked Questions

1. Can dogs experience joint pain when it rains?

The relationship between weather changes and joint discomfort in dogs is not as simple as “rain causes joint pain”. However, dogs with existing joint problems may show more noticeable stiffness or reduced mobility during certain weather changes. If these symptoms occur repeatedly, veterinary assessment is recommended.

2. Do dogs get “rheumatism”?

“Rheumatism” is not a single veterinary diagnosis. Dogs can develop different types of joint conditions, including osteoarthritis, hip dysplasia and patellar luxation. If your dog shows signs of joint discomfort, a veterinarian should assess the underlying cause.

3. What are the signs of arthritis in dogs?

Common signs include difficulty getting up, stiffness, reluctance to run or jump, difficulty using stairs, reduced activity and limping. Some dogs may not visibly cry out in pain, so owners should also pay attention to subtle changes in their everyday behaviour.

4. At what age should I start paying attention to my dog's joint health?

There is no fixed age that applies to every dog. Although senior dogs have a higher risk of degenerative joint problems, younger dogs can also develop joint conditions due to genetics, developmental abnormalities, injuries and other factors.

5. Can being overweight increase stress on a dog's joints?

Yes. Excess weight increases the load placed on a dog's joints during everyday movement. Maintaining a healthy body weight is therefore an important part of long-term joint care.

6. Can dogs with joint problems still exercise?

Many dogs still benefit from appropriate levels of activity to maintain muscle strength and mobility. However, the type and intensity of exercise should depend on the dog's individual condition. If your dog has a diagnosed joint problem, follow your veterinarian's recommendations when planning exercise.

7. Do dogs need to take joint supplements long-term?

Whether a joint supplement should be used long-term depends on factors such as your dog's age, health, diet and the severity of any joint problems. Before choosing a supplement, review its ingredients and feeding instructions. If your dog has an existing health condition or is receiving treatment, consult your veterinarian before use.
