The dose of borax or sodium tetraborate that is tolerated by dog and cat is below the minimum. Only small dose of it is allowed for some bacterial and fungi related diseases. Otherwise, borax is toxic just like it other chemicals that endanger human in the list of banned food additives in many countries. The toxicity of borax will disturb the nerve system that the body may experience tremor when pets are exposed to high amount of borax.

Heart seizure often occur when the borax is injected directly to the blood stream. The substance will contamine the flowing blood until it reaches the heart. As the heart denies such substance to enter it, the heart muscle uncontrollably try to pump them out and cause heart attack. 

  1. Coma

While the chemical entering the blood stream can cause seizure, when it eventually reaches the brain, it will cause the pets (any kind or breed of animals) to be in coma. Coma happens when the injection of borax happens too sudden some of the nerve cells in the brain stop working.

If this occurs, the pets will first experience high trembling followed by sudden pain in the head. If the owner does not take quick action, the pets will end up in coma.

The worst thing that could happen to pets who get overdosed of borax is death. Even though it is rarely happen, if a direct injection of borax in high concentration occurs, the pets will have all of their body’s function damaged. As a result, the body can no longer sustain itself and the pets will die.

This case is a rare one since not one case a pet is exposed to borax purposefully. The only purposeful act to let the pets die is when the pet has terminal illness in which no cure can let it be healthy again that the owner decides it is best to let them die.
