What is Borate Poisoning?
Sodium borate is a naturally occurring mineral and salt of a boric acid that is harvested from evaporated lakes. It is more commonly referred to as Borax and is used in laundry and cleaning products, as a pH buffer in biochemical labs, as a welding component, as a water softening agent, and in the creation of ceramic goods. It is used in some countries as an ingredient in food but is banned in the US. Dogs can exhibit signs of toxicity at approximately .02 ounces of boric acid per pound of bodyweight.
Borate, or sodium borate, is used in laundry detergent, cleaning products, and pesticides. If your dog ingests sufficient amounts of this ingredient, it can become toxic.

Types
Acute borate poisoning
This is the kind of poisoning that you would see if your canine ate a fairly substantial amount of the household product containing the sodium borate. This is most common with ingestions of borate as an ingredient in a pesticide such as roach killers and flea treatments.  
Chronic borate poisoning
Chronic borate poisoning is less common, but if they encounter it on the floor frequently, or from nibbling on plants sprayed with pesticides made with sodium borate, they can develop additional signs and symptoms. Weight loss, kidney damage, and hormone disruption can result from chronic exposure to this chemical.
Causes of Borate Poisoning in Dogs
Borate or boric acid can be found in a large variety of household products that your dog may encounter, either indoors or out. These can include:
  • Antiseptics
  • Concealers and foundations
  • Diaper creams
  • Enamels and glaze
  • Flea and tick medications
  • Insecticides
  • Medicated powders
  • Paints 
  • Rodent poisons
  • Shaving cream
  • Shower gel
  • Skin lotions
Diagnosis of Borate Poisoning in Dogs
Many of the symptoms of borax poisoning are common to other poisonings, such as excessive drooling, depression, lethargy, muscle weakness, and lack of coordination. The blue-green color of your pet’s vomit and diarrhea is somewhat unique and should point your veterinarian in the right direction. If certain concentrations of borate are left on the skin too long, it can also cause uncomfortable rashes, which your veterinarian may find during the physical exam, particularly on your dog’s face or paws.
The oral cavity and the esophagus will be checked for burns. General blood tests such as a complete blood count and a biochemistry profile will be completed along with a urinalysis. Approximately 40- 60% of the sodium borate will be excreted in the urine unchanged within about twelve to twenty-four hours. These tests will help rule out other toxins as well as assessing the continuing functionality of both the liver and the kidneys.
Treatment of Borate Poisoning in Dogs
Your veterinarian may choose to induce vomiting or opt to perform a gastric lavage for your dog if the ingestion was within the last two to three hours. This is done to remove as much of the physical toxin as possible before it is absorbed into the bloodstream. Although activated charcoal is often given at this time for most toxins, sodium borate tends to bind poorly to it, so it is often omitted from treatment. The symptoms of borate poisoning can sometimes induce dehydration, so supportive measures such as IV fluids and electrolytes are often given to combat this problem.
Any borate that remains on your dog’s skin will be washed off to prevent further burning of the skin. Anticonvulsants may also be given to the patient as needed. Borate goes through the kidneys before being expelled in the urine and can cause damage, so the functionality of the kidneys needs to be carefully monitored. In some cases, dialysis may be required.

Recovery of Borate Poisoning in Dogs
Because borate is processed through the kidneys, your dog’s doctor may choose to perform either dialysis or hemodialysis to protect the future performance of the kidneys. Dialysis, for humans, is generally a life-long treatment plan with dialysis occurring 2-3 times a week for the remainder of their lives. This usually only changes if the patient has a kidney transplant. Although dogs may also require dialysis as a lifelong treatment, it is more often used as a treatment for acute disorders, to temporarily ease the burdens to the kidneys and give them a chance to properly heal so that they can recover functionality. It is not widely available and is very costly.
Paying to treat borate poisoning out of pocket can be a major financial burden. Fortunately, most pet insurance companies reimburse claims within 3 days, putting 90% of the bill back in your pocket.

My pet has the following symptoms:
None That I Have Noticed
I have been at work for 5 hours, came home after my shift to see that some of the borax box was torn, but I haven’t noticed any symptoms within the time that I have been with him. Is there something we can give him to make sure he doesn’t get any symptoms?

Thank you for your question. If you think your puppy actually ate a lot of the borax, it would be best to have him seen by a veterinarian right away and probably started on IV fluids. In large quantities borax can be quite toxic to the kidneys as well as causing GI upset. If you think that only a little bit was eaten or the box was just chewed then you probably won't see any signs as it does take a fair amount to cause toxicity. You may notice GI upset, and if your puppy starts vomiting, diarrhea, becoming lethargic, or doesn't want to eat, then it would be best as well to have him seen by a veterinarian. I hope that everything goes okay. https://wagwalking.com/condition/borate-poisoning

Thank you for your question. I would think, with that diluted amount of borax, that she should be fine. It would be best to watch her for the next twenty-four hours, carefully, for any signs of vomiting, lethargy, diarrhea, or loss of appetite. If she shows any of the signs, or is pawing at her mouth or drooling, then it would be best to have her seen by a veterinarian right away. I hope that all goes well for her.

Vomiting
My grandmother said she has spread the substance around the home but I’m unsure of what she used or where she put it. But ever since then my dog had been vomiting up his food. He seems normal besides that. Wanting to go outside and being very calm. He’s a 5 lbs teacup Yorkie

My pet has the following symptoms:
Vomiting
Drooling
My dog Lola (50lb Plott hound) ate roach bait that my wife made (1 tbs peanut butter and 1 tbs borax mixed ) and then threw up a couple times and is now drooling, should i be worried?

Treatment of borax ingestion is induction of vomiting which Lola already did along with supportive and symptomatic care; you should ensure that she is kept hydrated but you should also visit your Veterinarian to be on the safe side for an examination.

My pet has the following symptoms:
Agitation
My dog ate a mixture of cat food and Boric Acid we had hidden under the couch as roach bait. It had been there for a while. He is 14 and usually very lethargic but he is now full of vigor and energy. I am assuming that the poison was either too stale or weak to cause any damage (also the roaches are doing quite well, thank you). Is there anything I should do other than keep an eye on him?

My dog is 35 pounds and ate a max of .5g of Borax out of an ant trap. The ant trap was 10mL with 5.4% borax. He’s not currently showing any symptoms but would that amount be enough to harm him?
