Is Borealis Honeyberry toxic to dogs?

Mildly. The ASPCA lists borealis 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. The blue berries are widely eaten by people, but Lonicera caerulea is not individually listed in the ASPCA toxic/non-toxic database, and the Lonicera genus is mixed (some honeysuckle species cause GI upset in pets). Treat as uncertain around cats and dogs and verify with a vet rather than assuming it is pet-safe.

Treat as uncertain around cats and dogs and verify with a vet rather than assuming it is pet-safe. 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 borealis 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 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: Borealis Honeyberry is mildly toxic to cats as well. See the full borealis honeyberry pet-safety guide for both species.
