Is Hazelnut 'Winkler' toxic to dogs?
Corylus avellana 'Winkler'
Mildly. The ASPCA lists hazelnut 'winkler' as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Corylus avellana is not individually listed on the ASPCA toxic or non-toxic plant database, so its status is uncertain; treat with caution and verify with a vet. The foliage is not known to be poisonous, but the whole nuts pose a real choking hazard and their high fat content can cause vomiting, diarrhoea, or pancreatitis in dogs and cats if eaten in quantity, so keep nuts away from pets.
What to do if your dog ate hazelnut 'winkler'
- Remove any plant material from your dog's mouth and move hazelnut 'winkler' out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
