Symptoms of Rat Poisoning in Dogs and Possible Dangers


As the weather gets chillier, mice and rats begin seeking shelter in warm areas … in other words, your house! Sadly, the start of fall indicates the start of mouse and rat poisoning, putting your dog or cat at risk.

Symptoms of Rat Poisoning in Dogs and Possible Dangers

In today’s blog, we’ll talk about the 4 different types of active ingredients found in these mouse and rat toxins. These toxins all work (and kill) in various methods, so attend!

While the most common type of mouse poison (e.g., brodifacoum, bromadiolone, and so on) typically impacts your dog’s capability to thicken effectively, brand-new EPA mandates by the government are lowering the accessibility of this specific type of poison (called an anticoagulant rodenticide or “ACR”). Regrettably, this indicates that newer, different types of toxins are turning up. Not even all veterinarians understand these newer active ingredients!

Depending upon what kind of mouse and rat poison was consumed, clinical signs can differ. When in doubt, please don’t use these poisons around your house if you have animals. I’m never ever a supporter of using these types of toxins, as they present a danger to wildlife, pets, and birds of victim (e.g., raptors like red-tail hawks, owls, etc.). I ‘d rather you use the more human snap trap — much more secure to you and your pet!

Anticoagulant rodenticides (ACR)

These ACRs inhibit the production of Vitamin-K dependent blood clot factors (made in the liver), so when consumed in harmful quantities by dogs or felines, it can result internal bleeding. Luckily, there’s an antidote for this kind of mouse and rat toxin: Vitamin K1, a prescription medication readily offered at your veterinarian. With ACR poisoning, clinical signs do not take affect for 3-5 days. Nevertheless, left without treatment, ACR poisoning can be deadly. Signs to look out for include:

  • Lethargy
  • Trouble breathing
  • Pale gums
  • Coughing (particularly of blood)
  • Vomiting (with blood)
  • Bloody nose
  • Swelling or bumps on the skin (e.g., hematomas)
  • Collapse
  • Bleeding from the gums
  • Death

Treatment consists of decontamination, Vitamin K1 orally (typically for 30 days), blood transfusions, plasma transfusions, oxygen, and encouraging care.

Cholecalciferol (Vitamin D3)

As an emergency crucial care veterinary specialist, this is my most disliked kind of poisoning. Only a percentage can result in severe poisoning in both dogs and cats. This type of mouse and rat poison results in an increased quantity of calcium in the body, causing kidney failure. Sadly, this type has no antidote, and is really pricey to treat, as pets normally need to be hospitalized for 3-7 days on aggressive therapy. Scientific signs include:

Treatment consists of aggressive IV fluids to flush the calcium and kidney toxins out, medications to help reduce the body’s calcium level (e.g., pamidronate, calcitonin, steroids, diuretics), and frequent blood work tracking.


While this kind of mouse and rat toxin seems like some ACR types (e.g., bromadiolone, brodifacoum), it’s completely unrelated to clotting and is not treated with Vitamin K. This is a mouse and rat poison does not have a remedy, and works causing brain swelling (e.g., cerebral edema). Scientific signs consist of:

  • Sleepiness or stress and anxiety
  • Walking drunk
  • Vomiting
  • Tremoring
  • Seizuring
  • Coma
  • Death

Treatment consists of inducing vomiting, administering activated charcoal, IV fluids, anti-seizure medication, muscle relaxants, and supportive care.


While this type of toxin is less common, you need to care, as it’s potentially harmful to you, your household, and your veterinary personnel! Phosphides are typically used to kill slightly larger creatures like moles and gophers (and is less frequently used as an active component in mouse or rat poisons). When consumed, the phosphides product a hazardous gas in the stomach called phosphine gas. Scientific signs include:

Treatment consists of not feeding your dog (no milk, bread or other “anti-poison home remedies”). That’s due to the fact that if there’s food in the stomach, it in fact makes the poisoning even worse and results in more phosphine gas production. This exact same gas is dangerous to people too, so make certain you do not breathe in the gas. Simply puts, if you’re owning to your veterinary center and your dog throws up at home or in the car, ensure to ventilate the area well (e.g., open the windows, turn on the ac system in the car, and so on). Also, when the veterinary staff causes vomiting in dogs consuming phosphides, they should do so outside or in a well-ventilated area. Treatment includes anti-vomiting medication, antacids, IV fluids, and encouraging care.

If you’re not scared off by mouse and rat toxins now, your dog’s in problem! When in doubt, keep all mouse and rat poisons out of reach of your household, children, and animals. If accidentally consumed, call your veterinarian immediately to discover how to treat it. With aggressive treatment, the diagnosis is reasonable to excellent, depending upon what type of poison they entered. Just like most poisons, the quicker you recognize the poisoning, the faster you treat it, the less problems for your animal (and the less cost to you!).
