Is fetch enough exercise for a dog?

What fetch is good for

Fetch packs a lot of effort into a few minutes. A dog sprints, brakes, picks up and sprints back. Trainers at Preventive Vet describe it as both mental and physical exercise, and the American Kennel Club lists it among good ways to exercise a dog. For a busy owner with an energetic dog, ten minutes of fetch can do what a much longer walk would.

This is why Zoomies gives fetch more weight than a walk. Twenty minutes of fetch adds 35 minutes to the meter.

Why it is not enough on its own

Fetch is one kind of exercise. It is short, repeated sprints in one place. It offers none of the things that make a walk valuable, such as new smells, new places and a steady pace that is easy on the body. The PDSA is clear that play does not replace a good walk.

A dog whose only outlet is the ball can also become fixed on it. Many trainers describe dogs that stay wound up after a long fetch session and find it hard to settle. That is experience and not hard science. One writer who looked for it found no study proving a link between fetch and compulsive behaviour. If your dog cannot think about anything but the ball, that is still a good reason to vary the day.

What vets say about the risks

The concern is the stopping and turning, not the running. The PDSA says the quick starts and sudden stops of chasing a ball can put strain on joints. It advises against throwing a ball for dogs that are still growing, elderly, injured, arthritic, overweight or prone to joint problems, and on wet, slippery or unstable ground.

Others agree. The Royal Kennel Club tells puppy owners to avoid exercise with sharp, sudden turns such as chasing a ball. VCA Animal Hospitals notes that the abrupt starts and stops may be a poor fit for overweight dogs. Preventive Vet lists torn toenails, muscle strains, ligament tears and worsening arthritis among the results of too much fetch.

It is fair to say what is not known. We did not find a published study that measures injuries from ball chasing or ball launchers. The warnings come from what vets and physiotherapists see in their clinics and from how joints work. That is a good reason for care. It is not proof that fetch is harmful, and none of these sources says to stop playing it.

How to play fetch more safely

• Warm up first. Walk for five or ten minutes before the first throw.
• Keep it short. A few minutes with breaks, not half an hour without stopping.
• Throw low. Roll the ball along the ground or throw it low, so your dog does not leap and twist in the air.
• Let the ball land. Ask your dog to wait, then send it once the ball has stopped. That removes the skidding stop.
• Choose the ground. Flat grass is best. Avoid wet, slippery or hard surfaces.
• Try water. Fetching from water gives the same fun with far less impact.
• Never throw sticks. The PDSA warns against it because of the injuries they cause.
• Ask for a sit between throws. It gives a breather and keeps excitement in check, as the AKC suggests.

How long should you play fetch?

No reputable source gives a time limit, because it depends on the dog. A sensible approach for a fit adult is five to ten minutes of throws with pauses, once or twice a day, as part of a longer outing. Stop while your dog is still keen and before the panting gets heavy. In warm weather, do much less.

Dogs that should skip fetch

• Puppies whose joints are still forming. See how much exercise a puppy needs.
• Older dogs and dogs with arthritis. The PDSA says walking and gentle running are fine for them, but chasing, jumping and skidding are best avoided.
• Overweight dogs, until some of the weight is off.
• Dogs recovering from an injury.

For these dogs, swap the ball for something gentler. Hide a toy for them to sniff out, scatter treats in the grass, or play a slow game of tug.

What to mix it with

The best week for most dogs has variety. Daily walks with time to sniff, a couple of short fetch sessions, some play and the odd swim or hike. We compare the options in the best exercise for dogs.
