A toxic dose of selenium caused pulmonary edema and death in a dog. This highlights the potential danger of selenium overdosage, even when combined with vitamin supplements.

Area of Science:

Veterinary Toxicology
Animal Pharmacology

Background:

Vitamin and mineral supplements are widely perceived as safe, even in high doses.
The public may lack awareness regarding the toxicity of certain elements in excessive amounts.

Observation:

A 3-year-old Chihuahua received an inadvertent intramuscular injection of a toxic selenium dose.
The selenium compound was mistakenly dispensed alongside a vitamin E preparation.

Findings:

The canine subject developed severe pulmonary edema following selenium administration.
The toxic selenium overdosage resulted in the animal's death.

Implications:

This case underscores the critical need for caution with selenium supplementation in animals.
