Senior dog food: what to change to protect their joints

While diet never replaces veterinary treatment, it directly influences the load on a senior dog's joints. Here are the levers that truly make a difference.

Weight, the primary factor for relief

Every extra pound translates to additional pressure on the hips, knees, and spine with each step. Even moderate weight loss in an overweight dog often improves mobility faster than medication alone.

Omega-3s, real anti-inflammatory support

Omega-3 fatty acids (fish oil, in particular) have a documented anti-inflammatory effect on arthritic joints. Many "senior" kibbles already contain them, but a supplement can be discussed with the vet in cases of confirmed osteoarthritis.

Glucosamine and chondroitin

These two compounds, naturally present in cartilage, are often offered as supplements for older dogs or those predisposed to dysplasia. Their effectiveness varies from one individual to another, but they are among the low-risk options to discuss during a consultation.

Adjust portions, not just the brand

A less active senior dog mechanically burns fewer calories than an adult dog. Maintaining the same portions as at 5 years old, without adjusting for decreased activity, is one of the most frequent causes of progressive weight gain after 7-8 years.

Hydration, often overlooked

A dog that drinks less than before may experience faster kidney function degradation, which complicates chronic pain management (some anti-inflammatories are contraindicated in cases of renal insufficiency). Favoring a partial wet diet can help dogs who drink little spontaneously.

And in everyday life, beyond the bowl

An adapted diet reduces the load on the joints but does not eliminate repeated mechanical impacts such as jumping onto the sofa or bed. Combining a healthy weight with simple adjustments like a soft-step dog ramp addresses the two main causes of joint wear: carried weight and impact with each jump.
