What Kind of Bleach Is Poisonous?

Concentrated bleach (agricultural products, industrial bleach) in high amounts can be poisonous.

Bleach is either chlorine-based such as calcium hypochlorite, or nonchlorine (peroxide-based). Your normal household cleaning products usually have a pH of11. The higher the PH value, the stronger the alkaline value in the product.

Agricultural bleach and bleach used for professional cleaning are almost ten times stronger than your household cleaning products and have a pH value of 12 to 12.5.

Why Is Bleach Poisoning Becoming Common?

Bleach can kill or control most viruses, bacteria, algae, and other pathogens. After Covid-19, many people have been house cleaning products frequently and thoroughly to stay safe. 

But unfortunately, this has increased the exposure of dogs to household cleaning products. Exposure to bleach can severely hurt a dog and can even lead to death, depending on how concentrated it was and how much the dog consumed.

How Can I Treat Bleach Contact In My Dog At Home?

#1. Call Your Veterinary Doctor

Your first should be to call the veterinary doctor. If the condition is mild, the veterinary doctor will advise you to take care of your dog at home.

#2. Rinse Its Mouth And Body

Make sure to thoroughly rinse the dog’s mouth with a lot of water so that the teeth, jaw, and gums are completely cleaned and have no traces of bleach on them. 

Next, get your dog under the shower to remove any bleach on the body. If possible, use a little bit of mild shampoo or dish soap if your dog has skin lesions and monitor the signs and symptoms.

#3. Encourage Your Dog To Drink

You should try to get your pup to drink a lot of water. This will ensure that whatever bleach remains gets diluted and therefore becomes harmless. 

Remember that your dog’s mouth would be hurting from the bleach, so it may not be easy for you to get it to drink. Try giving it cold water or milk with tuna juice so that the dog likes the drink a bit more.

#4. Don’t Try Your Dog To Vomit

You should never try to make your dog vomit if it has unknowingly ingested bleach. While coming back up, the bleach in the vomit will hurt your dog’s esophagus. 

It is possible that your dog can get ulceration in the esophagus, which is harder to treat than just plain old stomach ulcers. Additionally, your dog can breathe in some bleach-containing vomit, damaging his lungs.

What Will Happen at the Vet’s if the Dog’s Condition is Severe?

If the condition is severe, you have to take your pet immediately to a veterinary doctor. The treatment depends on the severity of symptoms in your dog. 

Treatment may include hospitalization for monitoring, fluid drip to correct electrolyte imbalance, or the veterinary doctor will give medications to treat stomach ulcers in your dog. 

Your dog’s stomach may be pumped by a method known as gastric lavage. The doctor may use activated charcoal to bind the toxins of your dog.

I am discussing a case study that may help you know better.

A 13-year-old female dog of weight 35.2 lb and a five-year-old male dog of weight 39.6 lb were admitted to Texas Veterinary Medical Centre to evaluate for acute vomiting, diarrhea, and ataxia. 

The two dogs were housed in the laundry and kitchen area for almost 6 hours when the dog owner was not home. When the owner returned home, he found both dogs in distress, and there were multiple areas of vomit and diarrhea lying on the floor. A severely chewed empty bleach bottle was also lying near the two dogs.

The dog owner reported that the two dogs were habituated to chewing empty plastic bottles. They chewedClorox, a regular bleach bottle containing 6.15 percent sodium hypochlorite, unknowingly. 

The dog owner estimated that the 2.83-liter bleach bottle was almost 75 percent full before being damaged. The owner even stated that there was no evidence that the two dogs were exposed to any other toxic materials.

While admitted to the hospital, the two dogs were very poorly responding and hypothermic. Both the dogs vomited yellow foamy liquid during their examination. The skin was damp and smelled of bleach and urine. 

The female dog was drooling excessively, had green nasal discharge, and had severely elevated sodium and chloride concentrations. The magnesium, phosphorous, glucose, and calcium concentrations were also high in female dogs. In male dogs, the sodium, chloride, BUN, creatine, and magnesium concentration was high after ingestion of bleach.

Both the dogs were admitted to the intensive care unit, and the doctors administered oxygen flow. They were placed under blankets to treat hypothermia. Despite continuous treatment, the female dog remained hypothermic and developed watery diarrhea.
