Carbon monoxide poisoning

Carbon monoxide (CO) is a colorless, odorless and tasteless gas produced by the incomplete combustion of carbon. It is very toxic to humans and animals as it inhibits oxygen uptake in the blood. In this blog post, you will learn how to recognize and prevent carbon monoxide poisoning in your dog.

Symptoms of carbon monoxide poisoning

The symptoms of carbon monoxide poisoning can vary depending on the duration and concentration of CO exposure. The most common signs include:

  • Weakness
  • shortness of breath
  • vomiting
  • Loss of consciousness
  • convulsions
  • coma
  • Death

If you notice these symptoms in your dog, you should see a vet or call animal rescue immediately. Rapid treatment with oxygen can be life-saving.
