My Dog Ate Prenatal Vitamins 

If your dog has gotten into the medicine cabinet and ate a handful of prenatal vitamins, you may be feeling anxious or guilty. You’re not alone, as it is quite common for pets to ingest human medications or supplements, including prenatal vitamins. Unfortunately, many pet owners don’t know what to do once their pup has eaten something they shouldn’t have. Read below to learn how these vitamins can affect your dog and what you should do if they have ingested them. 

How Can Prenatal Vitamins Affect Dogs? 

Both humans and dogs need specific vitamins and minerals in their diets to maintain their health. However, humans’ vitamin requirements are different from dogs. Prenatal vitamins pose a threat to dogs due to the high concentrations of iron, calcium, and vitamin D. Prenatal vitamins can also contain xylitol, a sugar substitute that is toxic to dogs. High levels of iron can result in cardiac arrest and liver failure in dogs. An excessive amount of vitamin D can cause calcium formations, resulting in kidney failure. There are prenatal vitamins designed specifically for pregnant dogs. Consult your veterinarian regarding dog pregnancy, including what vitamins and medications they need. 

Prenatal Vitamins Toxicity 

Symptoms from ingesting prenatal vitamins can vary depending on the dosage and active ingredients found in the vitamins. Common signs to watch out for include: 

  • Vomiting 
  • Diarrhea 
  • Lethargy 
  • Abdominal pain 
  • Elevated heart rate 
  • Agitation 
  • Low blood sugar 
  • Seizures 
  • Tremors 
  • Increased drinking and urination 


If your dog has ingested prenatal vitamins, you must contact your veterinarian and Pet Poison Helpline at (855) 764-7661 for medical assistance. Take your dog to the veterinary clinic so they can receive treatment. Your veterinarian may induce vomiting and administer activated charcoal to bind the toxins.

Your dog may be hospitalized for monitoring and symptomatic care. If you have more questions or concerns, do not hesitate to contact Pet Poison Helpline today.
