Bromethalin rat poison can be extremely toxic to dogs, causing severe symptoms and potentially life-threatening consequences.

Bromethalin is a highly potent neurotoxin that can cause seizures, tremors, and even death in dogs.

If your dog ingests bromethalin, it's essential to act quickly and seek veterinary attention immediately.

Symptoms of bromethalin poisoning can appear within 12-48 hours after ingestion and may include vomiting, lethargy, and loss of coordination.

What Is Bromethalin Rat Poison?

Bromethalin rat poison is a neurotoxin that can cause serious harm to your pet. It's often found in rat poisons that contain peanut butter and/or sugar to attract rodents.

If ingested, large doses of bromethalin can cause signs to manifest within 24 hours, while lower doses can take 1-3 days to show symptoms.

Rat bait can be easily accessible to pets, even if it's labeled as "pet-safe" or "dog resistant." It's not uncommon for dogs to get into rat bait, so it's essential to keep it locked up and out of reach.

To prevent accidents, keep rat bait in an area inaccessible to your pet. Periodically check to ensure all bait blocks are accounted for, as it's easy for pets to sniff out the bait.

Symptoms and Identification

Symptoms of bromethalin rat poison ingestion in dogs can be unpredictable and vary in severity. The symptoms can manifest anywhere from 1 to 5 days after ingestion.

The signs of ingestion can be subtle, such as mild stomach upset, or severe, including seizures, inability to walk, and even death. The quicker the onset of the signs, the greater the severity of the symptoms.

Some common signs of bromethalin rat poison ingestion include lethargy, labored or rapid breathing, pale gums, collapse, weakness, tremors, lack of coordination, and lack of appetite. These symptoms can also include unusual coloration in your dog's stool, nosebleeds, bloody diarrhea or urine, swollen joints, or seizures.

Here are the key symptoms to watch for:

  • Lethargy
  • Labored or rapid breathing
  • Pale gums
  • Collapse
  • Weakness
  • Tremors
  • Lack of coordination
  • Lack of appetite
  • Nosebleeds
  • Bloody diarrhea or urine
  • Swollen joints
  • Seizures
  • Unusual stool coloration

Causes

There are two primary causes of rat poison toxicity in dogs. These causes can be categorized into two main groups.

Eating the rat poison is the most direct cause of toxicity. This can happen if your dog ingests rat poison intentionally or accidentally.

Secondary exposure is another significant cause of rat poison toxicity in dogs. This occurs when your dog eats a rodent that has been intoxicated with rodenticide.

The two main causes of rat poison toxicity in dogs can be summarized as follows:

  • Eating the rat poison
  • Secondary exposure (eating a rodent intoxicated with rodenticide)

Symptoms

If your furry friend ingests rat poison, it's crucial to recognize the symptoms of poisoning. Lethargy is a common sign, along with labored or rapid breathing, pale gums, and collapse. Some pups may also have nosebleeds, bloody diarrhea or urine, swollen joints, or seizures.

Unusual coloration in your pet's stool is a red flag, as many rat poisons contain dyes. If you notice any of these symptoms, contact your vet or take Fido to the nearest emergency clinic immediately.

Bromethalin, a common ingredient in rat poison, affects the coating around nerves in the body, leading to neurologic signs. In small ingestions, your pet may experience mild stomach upset. In larger ingestions, symptoms can be life-threatening and include severe muscle tremors, seizures, and even death.

The onset of symptoms can occur within 4-36 hours after ingestion, or within 3-7 days. The severity of symptoms often depends on the amount ingested and the time it takes to show signs.

Here's a breakdown of the potential symptoms of rat poison ingestion in dogs:

Remember, if your pet ingests rat poison, contact your vet or the ASPCA Animal Poison Control Center at 888-426-4435 right away for assistance.

Treatment and Recovery

If your dog has ingested bromethalin rat poison, it's crucial to act quickly. Decontamination and treatment are key to preventing toxicity.

Most pet owners arrive at the clinic with enough time to prevent symptoms, so it's essential to seek veterinary care immediately. Emesis and activated charcoal are the only therapies known to prevent toxicity from bromethalin.

When giving activated charcoal, it's vital to monitor sodium levels and the hydration status of your patient. Signs of hypernatremia from activated charcoal and signs of bromethalin toxicosis can look very similar.

Treatment aims to lower CSF pressure and decrease swelling of the nerves, and may include mannitol, corticosteroids, and diuretics. However, symptoms often come back once these medications are stopped, as they can't reach the main site of action of bromethalin inside the myelin sheathes of nerves.

Decontamination & Treatment

Decontamination is a crucial step in treating poisoning in dogs. Inducing vomiting can be effective, but it's best to have a vet do it. If your dog has ingested rat poison within the past 4 hours, you may be able to induce vomiting under your vet's advice.

Since many rat and mouse baits have a delay in onset of symptoms, pets often arrive at the clinic when there's still time to prevent symptoms. Emesis and activated charcoal are the only therapies known to prevent toxicity from bromethalin.

Activated charcoal can be given to bromethalin cases, but it's essential to monitor sodium levels and hydration status. Signs of hypernatremia from activated charcoal and bromethalin toxicosis can look similar, but treatment and prognosis are very different.

In cases of bromethalin poisoning, not all dogs will die. Some lower doses can cause symptoms like ataxia, lethargy, and hind limb weakness that may eventually resolve. However, high doses, rapid onset of signs, and severe initial symptoms are poor prognostic factors.

Treatment for bromethalin poisoning typically involves lowering CSF pressure and decreasing nerve swelling. Mannitol, corticosteroids, and diuretics are often used, but symptoms can return once these medications are stopped.

Recovery can be a lengthy process, ranging from 1 week to 1 month, depending on the dosage ingested.

Monitoring your dog's condition closely is crucial during this time, and any signs of illness should be reported to your vet immediately.

The cost of treating poisoning in dogs can be quite high.
