In this guide
On the Zooplus UK page the medium Ultra Ball is a single ball. It is listed at £5.69 for one ball about 6.5 cm across, while its two-ball option is the small size, at £8.49 for 5.1 cm balls. The large is a single at £5.89.
The ball itself is plain: natural rubber, bouncy, floats, fits a launcher. Two decisions matter, which size suits your dog's mouth and whether to pay for a spare. The sections below take them in that order, then cover materials, durability and who should look elsewhere.
Our verdict
For a medium-sized dog, the Ultra Ball is a cheap, floating fetch ball. Zooplus UK sells the medium singly at £5.69, so a spare brings it to £11.38; fetch balls usually get lost rather than worn out.
- A good fit for
- Owners who throw with a Chuckit! launcher or play fetch in water and want a natural-rubber ball that bounces, floats and stays visible in grass
- We would skip it if
- Your dog chews balls apart, you cannot judge which size is too big to fit entirely in your dog's mouth, or you want a two-ball medium pack rather than two singles
Reasons to consider it
- Medium is about 6.5 cm across; Zooplus UK describes natural rubber that floats and works with Chuckit! launchers
- £5.69 for a medium single, with delivery in 1-3 working days and free delivery from £39
- Returns are open for 14 days from the day the goods arrive, for a full refund
The compromises
- The only pack of two on the Zooplus page is the small, at £8.49 for balls 5.1 cm across; the medium is sold singly
- The page gives no chew rating and says no toy is indestructible, so this is a fetch ball, not a chew toy
- No dog-weight range is given for medium; the pack shows only a multilingual MEDIUM label
What we have not verified: Price and returns terms come from Zooplus UK's page, and other UK shops may charge differently. Delivery charges below £39 are not stated beyond a note that shipping costs may apply, and no weight band for medium appears.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
Ultra Ball, Medium
Natural rubber that floats, bright orange and blue, launcher-compatible, and a medium single at £5.69; about 6.5 cm across.
Before you buy: No dog-weight band for medium, no chew rating, and the medium is not sold as a pair on the page read.
Price checked 16 October 2026. Retailer prices can change.Sizing: medium means 6.5 cm, and the choice is a safety call
Zooplus UK gives three diameters: 5.1 cm for the small, about 6.5 cm for the medium and 7.6 cm for the large. The medium is the middle size of the three. The limit is that the page gives no weight range for any size, and the pack shows MEDIUM in several languages without a dog-weight guide.
Size is also the one safety choice. A ball small enough to slip past the back of the mouth is a hazard, while one too big to carry is only an annoyance. A large-breed owner should look at the 7.6 cm large, at £5.89 on the same page. The call: hold a ball up to your dog's mouth first, then pick the size that cannot fit entirely inside it.
Price: £5.69 for a medium, and a spare for £11.38
The medium is £5.69 for one ball. The only two-ball pack on the page is the small, £8.49, or about £4.25 a ball, which is cheaper per ball but 1.4 cm narrower. Two mediums bought together come to £11.38. A fetch ball more often ends in a hedge or a pond than worn out, so a spare covers the usual failure. The call: buy two if your dog is a medium-ball dog.
Delivery changes the sums. The site banner gives free delivery from £39, and the page notes that shipping costs may apply, so a lone £11.38 order may pay for postage unless it rides with food or other supplies. Returns run 14 days from receipt for a full refund, though the support article does not say who pays return postage.
Materials, floating, and what the page does not say
Zooplus describes very durable natural rubber with a high bounce that also floats on water, and says it wipes clean. That separates it from a tennis ball, which soaks up water and gets heavier, so it suits a pond edge or a lake. The limit is that the page gives no bounce height or weight figure, and nothing about the rubber beyond calling it natural.
The page lists the colour as orange/blue and says the ball works with Chuckit! launchers. A launcher is a separate purchase, and the page gives no launcher size guide for the medium ball.
Durability and when to retire a ball
The page calls the rubber very durable but also says no toy is completely indestructible, and it advises supervising play, checking the toy regularly for damage and replacing it if damaged or missing pieces. The seller's caution is not a chew rating. A dog that gnaws a ball between throws will eventually cut the surface, and a cut or torn ball should leave the rotation. The call: buy it for throwing, not for unsupervised chewing.
A fetch-only dog keeps a ball for as long as it stays found, while a heavy chewer turns £5.69 into a recurring purchase. How long a ball lasts depends on the dog, and nothing on the page predicts it.
When to skip it
Skip the medium if you cannot judge your dog's mouth size, because the sizing guidance is thin and a ball one size too small is the one safety risk here. A toy-breed owner should look at the small pair at £8.49, and a large-breed owner at the large. When in doubt, size up: a ball too big is an inconvenience, and one too small is a hazard.
Skip it also if your dog is a dedicated chewer, or if you want a squeaker. The Ultra Ball does one job, which is to be thrown, found and thrown again, and a £5.69 single does it cheaply.
