Early Symptoms of Rat Poison Ingestion in Dogs

Rat poison (rodenticide) works by disrupting your dog's blood clotting or causing neurological damage. Symptoms vary by poison type, but here's what to watch for:

Poison TypeCommon SymptomsOnset Time
Anticoagulant (e.g., warfarin, brodifacoum)Bleeding from gums, nose, or in stool; weakness; pale gums; coughing blood; bruising; lethargy24–72 hours after ingestion
Bromethalin (neurotoxin)Tremors, seizures, hind-leg weakness, paralysis, disorientation2–24 hours (can be up to 72 hours)
Cholecalciferol (vitamin D3)Increased thirst and urination, vomiting, weakness, depression, kidney failure12–36 hours
Zinc phosphideVomiting, abdominal pain, breathing difficulty, shock15 minutes to a few hours

Even if your dog shows no signs, poisoning can be fatal without treatment. If you suspect exposure, act immediately.

Immediate Steps to Take After Rat Poison Ingestion

  1. Call for help – Phone your vet or the Pet Poison Helpline (855-764-7661) or ASPCA Animal Poison Control (888-426-4435) right away. Have the poison packaging ready to identify the active ingredient.
  2. Do not induce vomiting – Unless a professional tells you to, never make your dog vomit. Some poisons cause more damage coming back up.
  3. Keep the packaging – The label tells the vet exactly which antidote (like vitamin K1) is needed.
  4. Get to the vet – Bring your dog to Aborn Pet Hospital at 40951 Grimmer Blvd, Fremont, CA 94538. Call (510) 656-0223 so we're ready when you arrive.
  5. Stay calm – Your dog picks up on your stress. Keep them quiet and still to slow absorption.

Time is critical. Even if symptoms haven't appeared, early treatment dramatically improves the outcome.

Frequently asked questions

Can a dog survive rat poison without treatment?

It's unlikely. Most rat poisons are designed to kill rodents, and dogs are even more sensitive. Without treatment, anticoagulant poisons cause internal bleeding that can be fatal within days. Early veterinary care gives your dog the best chance.

What is the antidote for rat poison in dogs?

For anticoagulant rat poisons, vitamin K1 is the standard antidote. For other types, treatment is supportive—like IV fluids, anti-seizure meds, or blood transfusions. The exact antidote depends on the active ingredient, so bring the packaging.

Should I make my dog vomit after eating rat poison?

No, not unless a vet or poison control expert tells you to. Inducing vomiting can cause aspiration or worsen damage if the poison is caustic. Call your vet or Pet Poison Helpline first for guidance.

How much does rat poison treatment cost at a vet?

Costs vary widely based on the poison type, treatment needed, and whether hospitalization is required. It can range from a few hundred dollars for early decontamination to over a thousand for intensive care. Call Aborn Pet Hospital for a quote based on your dog's situation.
