When to See a Veterinarian
If you suspect your dog has eaten a toxic plant, don’t wait for symptoms to worsen:
Remove plant material from their mouth.
Call your veterinarian immediately.
Contact the ASPCA Animal Poison Control Center at 888-426-4435 for guidance.
Important: Even if your dog ate a non-toxic plant, large amounts of any plant matter can cause stomach upset. If your dog or cat exhibits any of these symptoms of plant poisoning, seek assistance immediately.
