In the event that there is a high volume of iron present in the blood, damage can occur within the cells. While iron is an essential nutrient for the regular functioning of a dog's body, when it is present in large quantities in the bloodstream, it can become lethal. Dogs may be ingesting unhealthy amounts of iron when they are being given multivitamins that are not appropriate for their age, size or health status, or when they are ingesting dietary supplements or pregnancy supplements that have been left within their reach but that are not intended for them.
Iron toxicity occurs in dogs in four separate stages.
Stage I (0–6 hours)
Stage II (6–24 hours)
Stage III (12–96 hours)
Stage IV (2–6 weeks)
The most common cause of iron toxicity is the ingestion of pills within the home environment. A toxic dose is considered to be in excess of 20 mg/kg.
Your veterinarian will need a thorough history of your dog's health, onset of symptoms, and possible incidents that might have precipitated/preceded this condition. A complete blood profile will be conducted, including a chemical blood profile, a complete blood count, and a urinalysis. If there is an abnormally high level of iron in the bloodstream, this will show up on the results of the blood tests. If it is suspected that your dog ingested iron pills, diagnostic imaging may be used to help locate them and to determine whether they can be removed from your dog's digestive system before they can be fully absorbed into the body.
