GHOSTCATCHER vs standard dog discs, tennis balls and fabric discs
Most dog toys are designed to look good to the person buying them. GHOSTCATCHER is designed around the animal catching it. Here is where that shows.
The best frisbee for dogs: seven things that decide whether a throw comes back

* Choking hazard: any dog toy can be torn and pieces swallowed. Supervise play, retire a disc once the rim is torn, and treat GHOSTCATCHER as a fetch disc — not a chew toy.
What the table measures
What the table is actually measuring
Three of the seven rows come from published vision research, not from our own testing. This is what each one is based on.
Colour: the one axis a dog separates cleanly
A dog has two cone types, not three. Their peak sensitivities sit near 429 nm (blue-violet) and 555 nm (yellow-green) (Neitz, Geisbauer & Jacobs, 1989, Visual Neuroscience 3:119-125). Red, orange and green all fall on the same axis of that two-cone system, so a red disc on a green lawn is a dull yellow-grey shape on a dull yellow-grey background. Blue against yellow is the one pair a dog resolves cleanly. That is the axis GHOSTCATCHER is coloured on. It is also why "bright orange for visibility" is a claim made for the owner, not the dog.
Ultraviolet: light your eye never receives
The adult human lens filters ultraviolet out almost completely. A dog's does not. Douglas & Jeffery measured the ocular media of 38 mammal species and found that roughly 61% of ultraviolet light reaches the dog's retina, against effectively none in the human eye (2014, Proceedings of the Royal Society B 281:20132995). GHOSTCATCHER prints a star pattern in UV-reactive ink on the top face. You will not see it. The published data supports what it does for the dog: more light and more contrast arriving at a retina that is already working in low light. We do not claim a dog sees a new colour.
Material: why hard plastic is not on our list
A disc a dog catches in the air lands on its teeth first. Rigid plastic discs are the reason most veterinary guidance on fetch toys warns about slab fractures of the upper carnassial. GHOSTCATCHER is woven canvas over a foam rim: no rigid edge anywhere on the disc. The trade-off is honest and it is in the table. A foam-and-fabric disc will not fly as far as a 235 g competition plastic disc, and it is not a chew toy. It is built for the catch, not for the distance record.

Head to head
Chuckit vs GHOSTCATCHER: two soft discs that float
The Chuckit! Paraflight is the soft disc most owners already know. Both float and both are soft on a dog's mouth; the differences are colour, construction and price per disc.
| Spec | Chuckit! Paraflight | GHOSTCATCHER |
|---|---|---|
| Construction | Nylon with a soft rubber edge | Woven nylon canvas over a closed-cell foam rim |
| Floats | Yes | Yes (confirmed in our own tests) |
| Colour | Orange and blue | Navy and yellow print plus a UV pattern dogs can see |
| Sizes | Several sizes | One size, 23 cm / 9 in, 130 g |
| Price per disc | About $13–$19 (US retail) | $11.66 ($34.99 for 3) |
Pick the Paraflight if you want a familiar disc in a size to match a small or very large dog. Pick GHOSTCATCHER if your dog keeps losing discs in the grass, or if you would rather have three discs at $11.66 each.

Honest limits
When GHOSTCATCHER is the wrong disc
Four cases, so you do not have to find them out after you buy.
- Distance and competition. Regulation disc-dog events use rigid plastic discs that fly much farther. A fabric disc is a backyard and park disc.
- Dogs that shred and swallow fabric. This is a catch-and-return toy, not a chew toy. If your dog destroys soft toys and eats the pieces, buy a solid rubber disc instead.
- Very small dogs. A 23 cm disc is too much disc for a dog much under about 7 kg (15 lb).
- Brachycephalic breeds. Flat-faced dogs have a harder time gripping a flying disc at all. Rolling it along the ground works better than throwing it.
If any of those describe your dog, a standard rubber disc is the better buy, and we would rather you spend the $34.99 on the right thing.

Specifications on this page describe the production disc: 23 cm (9 in), 130 g, woven canvas over a foam rim, floats, machine washable, no battery. Durability, floating and long-distance flight were confirmed in our own tests (not an independent lab). Patent pending. First run ships November 15, 2026.
