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