Keep Your Dog Fit: Exercise, the Rib Test and Healthy Joints

A fit dog is a happier, calmer, longer-lived dog. The good news: you don't need a gym membership, just the right amount of movement for your dog, a quick hands-on check and a little joint care.

How much exercise is enough?

There's no single magic number. A Border Collie and a Bulldog live in the same world, but their exercise needs are nearly opposite. As a baseline, most healthy adult dogs need 30 minutes to 2 hours of activity a day. High-drive working breeds like Huskies, Collies, Vizslas and German Shepherds often need 90-plus minutes plus mental work, or that energy goes into chewing, barking and digging. Flat-faced breeds like Pugs and Bulldogs need far less and overheat dangerously fast.

Age matters as much as breed. Puppies follow a rough guide of five minutes per month of age, twice a day, to protect growing joints. Seniors need gentler, shorter sessions to stay mobile without strain.

And don't forget the brain. A 15-minute sniff walk or a puzzle feeder can tire a dog more than a sprint, because scent work is mentally exhausting in the best way. Match the effort to the dog in front of you, and watch destructive behavior melt away.

The 10-second rib test

The scale won't always tell you if your dog is carrying extra weight. Your hands will. Run them along both sides of your dog's chest: you should feel each rib easily under a thin layer of fat, like feeling the back of your own hand. If you have to press hard or can't find them, your dog is likely overweight. From above, you should see a waist tucking in behind the ribs. From the side, the belly should slope up, not hang flat.

Vets go a step further with a 9-point Body Condition Score instead of one "ideal" weight, because a healthy weight for one dog can be too much for another of the same breed, depending on frame and build.

Why extra weight matters (and how to fix it)

Studies estimate that over 50% of dogs in the U.S. are overweight or obese, yet most owners rate their dog's body as "normal." The usual culprits are too many treats, table scraps and free-feeding, plus too little exercise. A few extra pounds on a small dog is like 20 or more on a person.

The stakes are real: excess weight is linked to diabetes, arthritis, heart strain and a shorter life. One landmark 14-year study found that lean dogs lived a median of 1.8 years longer than their slightly overweight littermates fed the same diet.

The best part? It's reversible. Use a measuring cup instead of eyeballing portions or free-feeding, cut back on table scraps, swap calorie-dense treats for veggies like carrots or green beans, and add daily walks. Recheck the ribs every few weeks. If you're unsure, ask your vet to score your dog's body condition and set a target weight and plan. It's the simplest health win you'll ever get.

Big dogs, happy joints

Great Danes, German Shepherds and Labradors steal hearts, but their joints carry enormous loads, and these breeds are prone to hip and elbow dysplasia and arthritis. Protection starts early: a proper large-breed puppy formula helps bones and joints grow at a safe pace, since growing too fast can damage them. Skip intense forced exercise and big leaps off furniture while those joints are still forming.

The biggest favor you can do is keep your dog lean, because every extra pound multiplies the stress on hips and knees. Steady, moderate exercise like walking and swimming builds the muscle that supports the joints better than hard sprints and jumps. Talk to your vet about joint-support supplements like glucosamine and omega-3s, and add ramps or rugs so older dogs don't slip or jump. Stiffness, limping or reluctance on stairs are early signs worth a vet visit.

Did you know? A 20-minute "sniffari," where your dog gets to stop and smell everything, can tire it out as much as an hour of fast walking.

Move together, measure the meals and check those ribs, and your dog will stay adventurous for years. 🐾
