Zinc toxicity and copper deficiency
The main concern when dogs ingest pennies is the risk of zinc toxicity and copper deficiency. Zinc is an essential mineral for dogs, but high levels can be toxic. Copper is also essential for dogs, but Penny can interfere with its absorption.
The toxic dose of zinc for dogs varies depending on the individual, but ingestion of just one Penny can cause symptoms.
Signs of zinc toxicity include:
* Vomiting
* Diarrhea
* Lethargy
* Weakness
* Difficulty breathing
* Pale gums
* Brown urine
* Anemia
* Liver damage
* Kidney damage
* Death
Copper deficiency can also cause a variety of symptoms, including:
* Anemia
* Lethargy
* Weakness
* Loss of appetite
* Weight loss
* Diarrhea
* Skin and coat problems
* Bone and joint problems
If you think your dog has ingested a penny, it's important to seek veterinary attention immediately. Treatment will depend on your dog's symptoms, and may include:
* Intravenous fluids and electrolytes
* Chelating agents to remove the zinc from the body
* Supplements to correct copper deficiency
* Antioxidants
* Other treatments to manage symptoms
Prognosis
The prognosis for dogs who ingest Penny is variable, depending on how quickly they receive treatment and the severity of their symptoms. With prompt treatment, most dogs recover fully. However, some dogs may develop permanent damage to their liver or kidneys.
Prevention
The best way to prevent your dog from eating Penny is to:
* Keep Penny out of reach of dogs.
* Teach your dog not to eat non-food items.
* If you do find that your dog has ingested Penny, seek veterinary attention immediately.
