Is Mountain Pine toxic to dogs?

Mildly. The ASPCA lists mountain pine 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. Pinus mugo is not individually listed on the ASPCA toxic or non-toxic plant lists, so its status is unconfirmed; treat with caution and verify with a vet. The ASPCA does list ponderosa pine (Pinus ponderosa) as non-toxic to cats and dogs, but pine needles, bark and sap can cause mild oral and gastrointestinal irritation if chewed.

Pinus mugo is not individually listed on the ASPCA toxic or non-toxic plant lists, so its status is unconfirmed; treat with caution and verify with a vet. The ASPCA does list ponderosa pine (Pinus ponderosa) as non-toxic to cats and dogs, but pine needles, bark and sap can cause mild oral and gastrointestinal irritation if chewed. 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 mountain pine.

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: Mountain Pine is mildly toxic to cats as well. See the full mountain pine pet-safety guide for both species.
