Is Philodendron Toxic to Dogs?

Toxic

☠️ Toxic to dogs — avoid

Philodendrons are toxic to dogs — the classic oxalate-crystal houseplant reaction: burning mouth, drooling, vomiting.

Every philodendron variety carries insoluble calcium oxalates, making it a mouth-burner rather than an organ toxin. Bites cause immediate pain and heavy salivation, and swallowed pieces add vomiting and diarrhea. It shares this profile with pothos, monstera, and peace lily — if you keep aroids around dogs, elevation is the strategy.

What makes it dangerous: Insoluble calcium oxalate crystals

Symptoms to watch for

  • Oral pain, head shaking
  • Drooling
  • Vomiting
  • Swollen lips/tongue (occasionally)

What to do right now

  1. Rinse the mouth; offer water or a little milk
  2. Monitor airway for an hour; feed bland food later
  3. Vet if swelling or persistent vomiting
