What to do if your pet is poisoned

So what do you do if you believe your pet has ingested or been exposed to a toxic plant? By the time your pet exhibits symptoms, organ damage could be setting in, according to a press release from the Veterinary Specialty Center of Seattle. To avoid life-threatening complications, act early and get treatment as soon as possible.

The faster your pet receives care, the better their outlook. The American Society for the Prevention of Cruelty to Animals maintains a detailed database with photos of plants that are toxic and non-toxic to dogs, cats and horses. The ASPCA also has an animal poison control hotline which you can call at 888-426-4435.

When you notice the signs or suspect a poisonous plant has been ingested, call your local veterinarian. You can reach the Mid-Columbia Pet Emergency Service in Pasco 24/7 at 509-547-3577, or just walk in without an appointment.

You can also call the pet poison helpline at 855-764-7661 for an $89 fee that includes follow-up consultation. Finally, the poison hotline is geared to help humans, but is always available at 800-222-1222 and could be helpful in an emergency.
