Pine trees are mildly toxic to dogs. Chewing needles or sap causes drooling and stomach upset, and swallowed needles can injure the gut mechanically.

Also known as: Pine, Christmas Tree, Pinus spp. · Pinus spp.

What makes it toxic

Resin acids and essential oils in needles and sap, which irritate the digestive tract, plus coarse needle fibers that can clump or scratch.

Warning signs to watch for

Drooling, gagging, vomiting and mild diarrhea within hours. Heavy needle eating can cause constipation, appetite loss or abdominal pain.

What to do if your dog eats it

Clear away chewed material and monitor. Contact your vet for persistent vomiting, no stool or a swollen painful belly — those suggest irritation or blockage needing exam.

Common questions

Can my dog drink the Christmas tree stand water?

Discourage it. The water itself is mildly risky from sap and bacteria, and preservatives or fertilizer tablets make it worse. Cover the stand.

Is sap stuck on fur a problem?

It is mostly a grooming nuisance — use pet-safe oil to soften it rather than letting the dog chew it off, which delivers a dose of resin.

Which is worse, pine or Norfolk Island pine?

Both are mild irritants rather than serious poisons — the true danger name to avoid is sago palm.
