Are Tennis Balls Safe for Puppies? What Small-Dog Owners Need to Know
Quick answer: yes — but only if the ball is the right size for the dog. A standard tennis ball is too large for most small breeds and a real choking hazard for puppies. The fix is sizing down to a 1.5-inch mini tennis ball.
Why standard tennis balls are risky for small dogs
A regulation tennis ball is roughly 2.5 inches in diameter — designed for the human hand and the human game. For a Yorkie, Chihuahua, Pomeranian, Maltese, or any dog under 15 lb, a 2.5-inch ball is awkward to carry, hard to grip, and just barely fits the mouth open wide enough to swallow whole. That last part is the dangerous one.
The American Veterinary Medical Association and most board-certified vets agree on one rule: any object that can fit fully inside a dog's mouth and pass the back of the throat is a choking hazard. For small breeds, that line sits right around 2 inches. A 2.5" ball can wedge in the airway during an excited fetch when the dog inhales sharply mid-grab.
The right size for small dogs and puppies
For dogs under roughly 25 lb, a 1.5-inch tennis ball is the standard recommendation. It's small enough to grip and carry, but too big to swallow. That sizing applies whether you're looking at felt tennis balls or rubber fetch balls.
- Under 10 lb (Yorkies, Chihuahuas, Pomeranians, Maltese, Toy Poodles): 1.5" is right.
- 10–25 lb (Pugs, Shih Tzus, French Bulldogs, mini Dachshunds, Cavaliers): 1.5" still works for most. 2" is fine for the larger dogs in this range.
- 25 lb and up: standard 2.5" tennis balls work — that's what they were designed for.
Our 1.5" squeaky mini tennis balls and 8-pack mini tennis balls are both sized for small breeds.
What about puppies specifically?
Puppies need a few extra considerations beyond just size:
1. Match the ball to the adult size, not the puppy size
If you have a Lab puppy who's 10 lb today but will be 70 lb at 18 months, don't use a 1.5" ball — the puppy will outgrow it in two months. Get the size right for the adult dog and let the puppy grow into it. Until then, supervise.
2. Watch for chewers vs. fetchers
Some puppies fetch and return cleanly. Others want to lay down and chew the ball apart. Felt-covered tennis balls can be chewed down to bare rubber within hours of intense chewing — at that point retire the ball. For heavy chewers, a textured chew toy like our spiky squeaky ball or our solid rubber treat balls is a safer bet.
3. Avoid the felt-shred risk
The felt cover on tennis balls is mildly abrasive. Healthy adult dogs don't typically have an issue, but for puppies who chew aggressively, felt particles can get swallowed. If your puppy is going to lay down and shred the ball, switch to rubber fetch balls instead.
4. Never leave a puppy alone with a ball
Especially during teething (3–7 months), puppies will work a ball obsessively. Always supervise during play and put the ball away when you leave the room. For unsupervised crate or downtime, use a stuffed fillable puzzle ball instead — it's designed for solo play.
Signs you should stop using a particular ball
- Felt is shredded down to bare rubber
- The squeaker is exposed or has been swallowed
- The ball has cracked or split
- Your dog is gulping at it instead of chewing
- Your dog is repeatedly trying to fit a too-big ball in their mouth
Replace, don't push it.
The bottom line
Tennis balls are safe for puppies and small dogs when sized correctly. The single biggest mistake is using a standard 2.5" ball for a small breed — that's where injuries happen. Size to 1.5" for dogs under 25 lb, supervise during play, and retire damaged balls early.
