Toxic to dogs. The ASPCA lists primrose as toxic to dogs. Low tier. A nibbled bedding plant followed by one mild vomit is the entire documented picture. Call for advice if vomiting repeats, the dog is very small or young, or the plant's identity is uncertain, because spring bedding holds stronger listings than this one.
Primroses are the cheerful rosettes of spring bedding, sold in trays of jewel colored flowers for borders, baskets and pots from late winter onward. Garden primrose, Primula vulgaris and its hybrids, sits at ankle height in exactly the beds a dog patrols. The ASPCA lists primrose as toxic to dogs, and its entry is a model of minimalism: unknown principle, mild vomiting. Owners deserve to know it is listed, and equally to know how small the listing is.
Look for a low rosette of crinkled, tongue shaped green leaves with a cluster of flowers on short stalks at the center: pale yellow in the wild type, and every bright color in bedding hybrids. They appear in trays and pots in late winter and spring, planted out in drifts along paths and house walls, all within easy mouthing range of a passing dog.
The ASPCA names the toxic principle of primrose as Unknown (the ASPCA lists no named toxic principle for this plant). Primrose's entry is the shortest in this tranche: toxic principle unknown, clinical sign mild vomiting. That brevity is information in itself. Some compound in the plant irritates the gut of a dog that eats it, the recorded outcome stops at mild vomiting, and veterinary literature has not handed the ASPCA a mechanism worth naming. This page reports the listing faithfully and resists the temptation, fatal to a database's credibility, to dress a small entry in borrowed drama.
The clinical signs the ASPCA lists for primrose are: mild vomiting. The typical case is quantity by stealth: a dog that mouths bedding plants on the daily garden round crops a primrose rosette a little at a time, and the owner eventually witnesses a mild vomit containing green leaf and a petal. That is the whole story the ASPCA records. The reason to still make a call when signs repeat is the company primroses keep: spring beds also hold bulbs and bedding plants with far heavier listings, and certainty about which plant was eaten is worth one phone call.
Most dangerous part: The leaves and flowers eaten from bedding displays and pots. There is no concentrated underground stage; the whole low plant is the exposure, in proportion to how much of it a dog eats.
Evening primrose is a different plant entirely, Oenothera, with its own separate status, and the shared name causes the usual confusion in both directions. This page covers Primula, the bedding and wild primrose. A label or a photo of the rosette and flower settles it; do not let the word primrose alone carry an identification in either direction.
Call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 right away, even if your dog looks fine. Some poisons take hours or days to show their worst effects. Do not make your dog vomit unless a veterinarian tells you to, and keep the packaging, a photo, or a sample of what was eaten to show the clinic.
No special campaign is warranted for a mild plant. Plant primrose drifts in front borders rather than the dog's own garden where you can, discourage bedding mouthing generally, and keep newly planted trays, which sit in a tempting row at ground level, behind a temporary barrier until they settle in.
For spring color in a dog used bed, garden marigold is listed by the ASPCA as non-toxic to dogs and covers a long season. Whatever bedding you choose, check the tray label against the ASPCA list before planting, because spring bedding is a mixed risk shelf. Whatever you plant next, check it on the toxic plants index approach: confirm the plant on the ASPCA toxic and non-toxic list under its scientific name, Primula vulgaris is the name to avoid here, before it goes in the ground or on the shelf.
Yes. The ASPCA lists primrose (Primula vulgaris) as toxic to dogs. Its toxic principle is Unknown (the ASPCA lists no named toxic principle for this plant), and the signs it lists include mild vomiting.
Call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435, or the Pet Poison Helpline on (855) 764-7661 straight away. Note what part of the plant was eaten and roughly how much, keep any remaining plant material to show the clinic, and do not make your dog vomit unless a veterinarian tells you to.

It is listed, and the listing is mild: the ASPCA records an unknown principle and mild vomiting. Listed is not the same as dangerous in the sago palm sense, and this page keeps the two ideas separate on purpose.
That matches the listing. Move the puppy's access with a low barrier, watch for any repeat, and call your veterinarian if vomiting continues or the puppy seems unwell, mentioning the other plants in the same bed so nothing stronger is missed.
