Is Tundra Honeyberry toxic to dogs?

Mildly. The ASPCA lists tundra honeyberry 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. Humans eat the berries readily, but Lonicera caerulea is not individually listed by the ASPCA, and the wider Lonicera genus is mixed in toxicity (some honeysuckle species cause GI upset in pets). Treat with caution around cats and dogs and confirm with a vet rather than assuming pet-safe status.

Treat with caution around cats and dogs and confirm with a vet rather than assuming pet-safe status. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to tundra honeyberry.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Tundra Honeyberry is mildly toxic to cats as well. See the full tundra honeyberry pet-safety guide for both species.
