How do I keep my senior dog from getting overweight when he can't exercise much?

Short answer
Focus primarily on portion control, since diet has a much larger effect on weight than exercise alone, especially once a dog's activity is genuinely limited by joint stiffness or other age-related changes. Measure food precisely with a kitchen scale, reduce treats or swap them for lower calorie options, and add whatever gentle movement your dog can comfortably manage to support the calorie deficit diet creates.
Why diet matters more than exercise here
For a dog with genuinely limited exercise capacity, burning off extra calories through activity simply is not a realistic option the way it might be for a healthy, mobile dog. This makes portion control the primary tool for weight management, since reducing calories in is far more achievable and reliable than trying to increase calories out for a dog whose movement is restricted.
Practical steps for tighter portion control
Weigh food with a kitchen scale rather than estimating with a scoop, since scoops can vary considerably in how much they actually hold depending on how they are filled. Reduce treats to a genuinely small portion of daily calories, or replace calorie dense biscuits with pieces of plain vegetables or lean cooked meat that add flavor and reward without much caloric cost.
Adding whatever movement is genuinely possible
Even a dog with significant mobility limits often has some capacity for gentle movement, whether that means a very short, slow walk, some light play from a lying position, or simply standing and shifting weight during a grooming session. Every bit of movement helps somewhat, though it should be treated as a supplement to careful portion control rather than the primary weight management tool for a dog in this particular situation. Checking in with your vet about what level of movement is genuinely safe for your dog's specific condition helps you set realistic, achievable expectations.
Key takeaways
- Portion control matters far more than exercise for weight management when activity is genuinely limited.
- Weigh food with a kitchen scale rather than a scoop for accurate, consistent portions.
- Swap calorie dense treats for lower calorie options like plain vegetables or lean cooked meat.
- Add whatever gentle movement is genuinely possible as a supplement to careful diet management.
