If you've got a dog that loves to fetch, you already know how quickly tennis balls get destroyed. Chewed, soggy, and lost within days — buying brand new balls at full price feels like a waste. That's where used tennis balls come in, and for dog owners in the UK, they're an absolute no-brainer.
Why Used Tennis Balls Are Perfect for Dogs
Dogs don't care whether a ball has been used in a Wimbledon warm-up or a local club session. What they care about is the bounce, the size, and whether it fits in their mouth. Used tennis balls tick every box — and at a fraction of the price of new ones.
They're also better for the environment. Millions of tennis balls are discarded every year after they lose their competitive bounce. Giving them a second life as dog toys is a simple way to reduce waste without compromising on fun.
What to Look For When Buying Used Tennis Balls for Dogs
Not all used tennis balls are equal. Here's what matters:
- Felt condition — dogs love to chew the felt off, so heavily worn balls are fine for fetch but may not last as long
- Bounce — for fetch, you want a ball that still has some life in it. Flat balls are less engaging for energetic dogs
- Size — standard tennis balls are ideal for medium to large dogs. Always supervise smaller dogs to avoid any choking risk
- Quantity — dogs lose balls constantly. Buying in bulk saves money and means you're never caught short
Which Grade Should You Choose?
Used tennis balls are typically graded by condition. For dogs, you don't need the best — here's a simple guide:
- Grade A — excellent condition, minimal wear. Great if you want balls that last longer, but overkill for most dogs
- Grade D — good condition with some wear. A solid all-rounder for regular fetch sessions
- Grade F — budget grade, more heavily worn. Perfect for dogs — they'll destroy them anyway, so why pay more?
For most dog owners, Grade F is the sweet spot. You get the most balls for your money, and your dog genuinely won't notice the difference.

Frequently Asked Questions
Are used tennis balls safe for dogs?
Yes, for the vast majority of dogs used tennis balls are perfectly safe for fetch and play. Always supervise play and replace any ball that has been chewed into small pieces.
How many tennis balls should I buy?
For a single dog, a bag of 12–20 balls will typically last a few weeks depending on how enthusiastic your dog is. Buying in bulk is always better value — our 100-pack and 200-pack are popular with dog walkers and kennels.
Do used tennis balls still bounce?
Grade D and above will still have a reasonable bounce for fetch. Grade F balls are more worn and may bounce less, but most dogs are happy chasing them regardless.
Can I recycle tennis balls after my dog is done with them?
Yes! Several UK charities and recycling schemes accept old tennis balls. Buying used and then recycling is the most sustainable option.
