## Quick answer

Yes. Dandelion appears on the Royal Veterinary College's "Wild Garden Herbs/Weeds/Flowers" safe list in its "Feeding Your Guinea Pig" factsheet (Dec 2022), and it is probably the best-known forage green in the guinea-pig world. A few leaves and flower heads join the rotation from unsprayed ground.

One honest limit: only RVC names dandelion in our register, and no feeding study of this plant in guinea pigs exists. Our recommendation is that dandelion is a safe rotation green — the site owns that call, and the Single source flag on this page says exactly how much evidence stands behind it.

## Is dandelion good for guinea pigs?

Dandelion fills the weeds-and-herbs slot inside the fresh 10–15% of the diet on the RVC factsheet, with grass hay making up the bulk of the day around it. Its registered role is variety and enrichment — a plant guinea pigs reliably recognize and eat with enthusiasm.

No source in our register publishes vitamin C or mineral figures for dandelion, so do not count it toward the 10–30 mg of vitamin C guinea pigs need daily. The vegetables those sources name for that job — bell peppers, kale, parsley — stay the reliable carriers; dandelion is the forage, not the supplement.

## How to feed dandelion

Pick from ground you know has not been sprayed — lawn edges treated with herbicide, roadside verges and dog-walked strips are exactly where this common plant collects what you do not want. Rinse the leaves and flower heads, and serve them fresh and raw only.

The first serving should be small, watched, and followed by the usual dropping check the next day — the gradual-introduction rule every new green gets. Rotate dandelion with other wild herbs and shop-bought greens instead of serving the same plant every day.

## Frequently asked questions

**Q: Can guinea pigs eat dandelion flowers?**

Yes — RVC lists the plant with no part qualification, so the yellow flower heads sit inside the safe listing along with the leaves. Serve them fresh, raw and unsprayed, in the same small, rotated portion as the greens.

**Q: Can guinea pigs eat dandelion every day?**

We rotate it rather than serving it daily. Wild herbs sit inside the fresh 10–15% band of the diet, and the register gives no frequency figure for dandelion specifically — a few times a week, swapped with other greens, is how our pages handle that gap.

**Q: Can guinea pigs have dandelion from the lawn?**

Yes, if the lawn is genuinely unsprayed and away from dog traffic. The plant itself is the safe part; the picking location is what turns a safe green into a bad idea. Wash everything before it reaches the cage.

**Q: What about plants that look like dandelion?**

The yellow-composite lookalike cluster — cat's-ear, hawkbit, sow thistle — lands inside the edible weeds group on the RVC list, which is why misidentification risk stays low here. The dangerous lookalikes are the ones RVC's "confident in identification" warning exists for: pick only plants you can name.

## Safety notes

Introduce any new food gradually: a small taste at first, building up over a week or so, and keep every serving fresh and raw. Hay stays the main event at around 80% of the day's eating, with fresh vegetables as the supplement.

**When to contact your vet**: Guinea pigs hide illness well. Contact your vet promptly if your guinea pig stops eating or passes fewer droppings, seems lethargic or in pain, has diarrhea, or shows any sudden change in behavior — small pets go downhill fast, and same-day advice is always the safe call.
