Symptoms of holly poisoning in dogs

  • Vomiting and diarrhea
  • Drooling
  • Lip smacking and head shaking from the spiny leaves

Why holly is toxic to dogs

Saponins are soap-like compounds that irritate the lining of the stomach and intestines. They are poorly absorbed, so the effects are mostly limited to vomiting, drooling and diarrhea.

What to do if your dog ate holly

  1. Remove plant pieces from your dog's mouth and move dogs away from the plant. Wipe sap or pollen off the fur and paws with a damp cloth.
  2. Call your vet or animal poison control for advice: ASPCA Animal Poison Control: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661.
  3. Identify the plant. Take a photo or bring a piece (or the plant label) to the vet, and estimate how much was eaten and when.
  4. Do not make your dog vomit unless a vet tells you to. Home remedies such as hydrogen peroxide or salt can cause serious harm.
  5. Watch for vomiting and diarrhea, drooling, lip smacking and head shaking from the spiny leaves. Go to a vet if signs are severe, last more than a day, or your dog has trouble breathing or swallowing.

Treatment and outlook

Signs are usually mild and self-limiting. A vet may give anti-nausea medicine and fluids if vomiting or diarrhea is persistent, or if a small or young pet becomes dehydrated.

How to keep your dog away from holly

  • Place holly on high shelves or in hanging planters out of reach of paws and tails, or in a room your dog cannot enter.
  • Give your dog something better to chew: chew toys and puzzle feeders reduce boredom chewing.
  • Pick up fallen leaves, petals and pollen promptly, and empty vases where pets can reach them.
  • Holiday decorations add extra risks: tinsel, ribbon, ornaments and light cords. Supervise dogs around the tree and table.
