Here are the steps you should take:
1. Call your veterinarian or the ASPCA Animal Poison Control Center (APCC) at (888) 426-4435 immediately.
2. Provide the APCC with the following information:
* The name and weight of your dog
* The amount of borax ingested
* The time of ingestion
* Any symptoms your dog is exhibiting
3. Follow the veterinarian or APCC's instructions.
Borax is a toxic substance that can cause serious health problems in dogs, including:
* Vomiting
* Diarrhea
* Seizures
* Kidney failure
* Death
Do not induce vomiting or give your dog any other medication without first consulting a veterinarian.
Remember: Time is of the essence when it comes to treating poisoning. The sooner you seek veterinary attention, the better the chances of a successful outcome.
