Selenium
Supplements
Risks:
- Poisoning
Selenium is an essential trace mineral for dogs, important for thyroid function, reproduction, and DNA synthesis. It also has antioxidant properties and can support immune health. Most dogs receive sufficient selenium from a balanced diet, so supplementation is usually unnecessary unless directed by a vet. Selenium toxicity can occur with over-supplementation and cause hair loss, skin lesions, nervous system abnormalities, and in severe cases, paralysis and death. Keep selenium supplements out of reach of dogs and follow dosage carefully if prescribed. If you suspect selenium toxicity, contact your vet immediately.
