Fetch is the default way most people exercise a dog, and the equipment matters more than people assume — both for how long it lasts and for what it does to your dog’s teeth and joints.

The tennis ball problem
Start here, because most people are using the wrong toy without knowing it.
Standard tennis balls are made with an abrasive fuzzy coating designed to grip a racket and a court. That same texture picks up grit, and a dog carrying and chewing one is essentially running sandpaper across its teeth.
Veterinary dentists see a characteristic pattern from it: worn, flattened molars and canines, sometimes down to the pulp, which requires extraction. It takes years, which is why owners rarely connect the two.
They also compress: a dog with a large jaw can flatten a tennis ball at the back of the throat, and re-expansion has caused fatal obstructions.
Verdict: occasional use is unlikely to do serious harm. Daily use for years is a genuine risk. Sized-up, smooth alternatives are better.
Better balls
Solid rubber fetch balls. Smooth surface, no abrasive coating, high bounce, and they float. The standard replacement.
Chuckit! Ultra Ball
Natural rubber, smooth surface, bright colours that are easier for a dog to see, and it floats. Buy a size that cannot fit fully behind the back teeth — when in doubt, size up.
Sizing matters more than anything else. A ball should be too large to pass beyond the molars. For most medium dogs that means a medium or large; for a Labrador, a large. Small balls are a genuine choking hazard for big dogs.
Launchers
A throwing arm adds distance and saves your shoulder. It also means you never pick up a slobbered ball.
Chuckit! Classic Ball Launcher
The simple version does everything you need. Pick up the ball by pressing the cup over it, and throw with a smooth overarm motion rather than a whipping one for better control.
Use the launcher thoughtfully. It multiplies the distance, which multiplies the sprinting, the skidding stops and the high-speed turns — all the things that are hard on shoulders and cruciate ligaments.
Floating and water toys
For dogs who swim, buoyancy and visibility matter.
Rubber balls that float are ideal. Rope-and-ball combinations throw further over water and are easy to spot. Avoid anything that waterlogs or sinks.
Rinse salt and chlorine off toys after use; both degrade rubber quickly.
Tough toys for the field
KONG Extreme Dog Toy
The black rubber compound handles serious chewers and the erratic bounce makes a fetch retrieve more interesting than a straight roll. Not for water — it can fill and sink.
KONG Classic Dog Toy
Softer red rubber, gentler on teeth, ideal for dogs who are not destructive. Doubles as a stuffable enrichment toy when you get home.
How to throw better
This section matters more than the gear.
Throw along the ground, not high. Leaping for a ball and landing awkwardly is a leading cause of cruciate and shoulder injuries. A rolling or low ball keeps all four feet nearer the ground.
Throw in a straight line. Fast changes of direction at speed are where joints get damaged.
Warm up first. Five minutes of walking and trotting before the first throw, every time.
Limit the number. Ten to fifteen throws is plenty for most dogs. An hour of continuous sprint-and-stop is athletic training, and few pet dogs are conditioned for it.
Vary the game. Ask for a sit before the throw, hide the ball and let the dog find it by scent, throw into long grass so it has to search. All of this tires a dog more than repetition and does it more kindly.
When fetch becomes a problem
Some dogs become genuinely obsessive: screaming at the ball, unable to settle, refusing food, fixated on any round object.
This is not a well-exercised dog. Repetitive high-arousal chasing floods the system with adrenaline and cortisol, and a dog in that state is wound tighter afterwards, not calmer. The behaviour self-reinforces, and the dog needs more each time.
If that sounds familiar:
- Retire the ball entirely for two to four weeks
- Replace it with sniffing walks, scent games and puzzle feeding
- Reintroduce fetch, if at all, as a short structured game with clear start and end cues and a maximum of ten throws
Outward Hound Hide-A-Squirrel Plush Puzzle Toy
Useful as a replacement activity: the dog extracts squeaky squirrels from a plush trunk, which uses the search instinct rather than the chase drive. Supervise, since it is not a chew toy.
What to avoid outdoors
- Sticks. Serious mouth and throat injuries are common, and some are life-threatening.
- Stones. Fractured teeth and intestinal obstruction.
- Small or compressible balls for large dogs.
- Frisbees thrown high, which produce exactly the twisting landings that damage joints. Floppy fabric discs thrown low are far better.
- Damaged toys. Check for splits and swallowable pieces after every few sessions.
A sensible kit
One correctly sized rubber ball, a launcher, and a floppy disc if your dog likes them. Throw low, count your throws, warm the dog up, and stop before the dog wants to.
That is a fetch routine that will still be working when your dog is ten.
