As you can see dock leaves, are high in acidic content and phosphorus. They also contain a little calcium.
This means that they are not recommended for guinea pigs to eat and should be avoided due to the plant’s acidic and phosphorus content.
They do look like the kind of leaves you might be able to feed a guinea pig, but because of their content, they are not recommended.
If they happen to nibble one, then do keep an eye on them and if you see any detrimental effects then it would be worth consulting a veterinary surgeon.
