Why Tennis Balls Are Bad for Dogs: Safer Fetch, Healthier Teeth, Better Breathing 🐶🎾

By Dr Duncan Houston

Quick Answer

Tennis balls can be risky for dogs because the fuzzy outer surface can wear teeth down over time, and the ball itself can become a choking or airway obstruction hazard, especially in dogs that chew, crush, or try to hold the whole ball in their mouth. Safer fetch toys are usually smooth rubber or silicone toys made for dogs, sized correctly, and ideally designed so air can still pass if the toy gets wedged. (Vca)

Tennis balls look harmless, and dogs absolutely adore them. Unfortunately, “my dog loves it” and “this is a smart toy choice” are not always the same thing. In practice, tennis balls can create two major problems: gradual dental wear and acute choking or obstruction risk. (Vca)

The good news is that you do not need to ruin fetch. You just need to make it safer.

🧠 Why Tennis Balls Are Risky

There are two main concerns veterinarians talk about with tennis balls.

🦷 1. They can wear teeth down

The fuzzy felt on a tennis ball is abrasive. Repeated chewing on that rough surface, especially once dirt and sand get trapped in it, can gradually wear the teeth down like sandpaper. VCA specifically notes that obsessive chewing on the scratchy tennis-ball surface can wear teeth over time, and AKC quotes a board-certified veterinary dental specialist warning that the fuzz becomes even more abrasive once loaded with grit. (Vca)

⚠️ 2. They can become a choking or airway hazard

Tennis balls can also be crushed, split, or lodged in the back of the mouth or throat. AKC warns that dogs with strong jaws can break tennis balls and that pieces or lodged balls can create serious choking hazards. BluePearl also lists tennis balls among common foreign bodies that can create emergency internal complications if swallowed. (American Kennel Club)

🦷 How Tennis Balls Damage Teeth

A dog’s enamel protects the more sensitive structures underneath the tooth. Once that enamel is worn away, it does not grow back.

With tennis balls, the issue is usually not one dramatic injury. It is slow, repetitive damage.

Things that make dental wear worse include:

• obsessive chewing between throws

• sandy or gritty outdoor play

• dogs that clamp and grind rather than simply retrieve

• frequent daily use over long periods

That is why some fetch-obsessed dogs develop the classic worn, flattened look on their canine teeth and premolars. VCA advises avoiding abrasive surfaces and specifically calls out tennis balls as a cause of tooth wear over time. (Vca)

🚩 Signs Your Dog May Already Have Tennis-Ball Tooth Wear

Watch for:

• flattened or blunted tooth tips

• brown or darker areas where dentin is showing through

• hesitation grabbing toys

• chewing more carefully than before

• bad breath or plaque collecting in worn areas

If you notice these changes, it is worth booking a dental check. Tooth wear often sneaks up quietly, then suddenly your dog has a mouth that looks like they have been stress-chewing a tennis court.

💨 How Tennis Balls Become an Airway Risk

The choking risk is not just about swallowing the ball whole. It is also about the way a ball can compress in the mouth, move backward, and then wedge where it should absolutely not be.

Dogs at highest risk include:

• large breeds with wide mouths

• intense fetch dogs

• dogs that catch toys in mid-air

• dogs that crush and chew balls between throws

• dogs that like carrying multiple balls at once

AKC notes that some dogs can break tennis balls in the mouth and that halves can lodge dangerously in the back of the throat. VCA also warns that toys that fit too easily in the mouth are more likely to become choking dangers. (American Kennel Club)

🚨 Signs of Choking You Should Never Ignore

Get urgent veterinary help if your dog suddenly shows:

• pawing at the mouth

• gagging or retching

• distress or panic

• wheezing or struggling to breathe

• blue, grey, or pale gums

• collapse

This is a true emergency. Even if the object comes out, your dog should still be checked, because swelling, aspiration, or trauma can follow.

✅ Safer Fetch Toy Alternatives

If your dog loves the shape and chase of a ball, swap to a toy designed for dogs instead of one designed for Wimbledon.

Look for:

• smooth rubber or silicone instead of fuzzy felt

• a size larger than your dog can fully fit behind the tongue

• a little give rather than rock-hard material

• high visibility colors for easier outdoor play

• durable construction without easy-to-tear parts

VCA recommends toys that are not so small they can fit fully in the dog’s mouth and advises using the fingernail rule: if you cannot indent the toy with your nail, it may be too hard and could fracture teeth. (Vca)

🛍️ What to Look for in a Safer Fetch Toy

Correct size

Go larger if you are unsure. A toy should not disappear into your dog’s mouth like it is trying to stage a magic act.

Safer material

Choose dog-safe rubber or silicone. Avoid fuzzy coatings that trap grit and avoid ultra-hard materials that fail the fingernail test. (Vca)

No loose parts

No ribbons, weak seams, or easy-to-rip coverings. Broken toy pieces can become their own separate emergency. (Vca)

Supervised use

Even “safe” toys are only safe until your dog decides to invent a new way to destroy them.

🔄 If Your Dog Is Obsessed With Tennis Balls

You do not need to go from tennis balls to emotional devastation overnight.

A practical transition plan:

1. Remove free access

Do not leave tennis balls lying around for idle chewing.

2. Introduce a better fetch toy

Use a purpose-made rubber or silicone dog ball.

3. Reward the swap

Make the new toy exciting with treats, praise, and short fun sessions.

4. Reduce chewing time

Fetch toy means fetch, not lying in the yard slowly sanding the face off the molars.

5. Teach “drop”

A reliable drop cue is one of the best safety behaviours any fetch dog can learn. AKC specifically recommends teaching “drop it” so the ball can be taken away quickly if needed. (American Kennel Club)

🎓 How to Make Fetch Safer

A few simple changes make a big difference:

• supervise all ball play

• avoid letting your dog sit and chew the ball between throws

• encourage ground pickups instead of dramatic airborne catches

• retire damaged toys immediately

• use one toy at a time

AKC also notes that supervised play is key and warns against allowing risky tennis-ball habits to continue unchecked. (American Kennel Club)

🪥 Protecting Teeth Beyond Toy Choice

Safer toys matter, but dental protection should also include:

• daily brushing with dog toothpaste

• regular dental checks

• VOHC-accepted dental products when appropriate

If your dog already has visible tooth wear, that is even more reason to step up oral care and get a veterinary dental assessment.

🐾 Final Thoughts

Tennis balls are not the innocent little yellow-green icons of dog joy that most people assume they are. They can gradually wear down teeth, and in the wrong moment they can create a frightening choking or obstruction emergency. (Vca)

The fix is simple: choose safer fetch toys, size them properly, supervise play, and do not allow prolonged chewing on abrasive or breakable balls.

Your dog still gets the thrill of fetch. You get fewer dental bills and a much lower chance of a heart-stopping airway emergency. That is a pretty good trade.

❓ FAQ

Are tennis balls ever okay for dogs?

Very limited, supervised fetch is lower risk than free chewing, but they are still not an ideal dog toy because of tooth wear and choking concerns. (Vca)

What is the safest replacement for a tennis ball?

A purpose-made rubber or silicone fetch toy that is appropriately sized, not too hard, and difficult to destroy is usually a much safer choice. (Vca)

Are dog-branded tennis balls safer?

Some may be better than standard sports tennis balls, but fuzzy abrasive surfaces and choking concerns can still remain. Smooth dog fetch toys are usually the safer option. (Vca)

What should I do if my dog chokes on a ball?

Treat it as an emergency and contact a veterinarian or emergency clinic immediately. Even if the object is removed, your dog should still be checked. (BluePearl Pet Hospital)
