Generally, eucalyptus oil has many health benefits such as to combat flu and colds, acts as a natural expectorant, boosts the immune system and reduces blood pressure (give more details). However, dogs could be poisoned by ingesting eucalyptus oil.
Currently, there are no well-controlled studies about whether dogs can tolerate eucalyptus oil or not. In general, canine should avoid ingesting things that human take as it might be harmful for dogs due to their physiology differences with human body. Some cases have been reported where eucalyptus oil poisoning occurred in dogs.
In case of ingestion, toxicity may occur as the eucalyptus oil is a toxic substance. Eucalyptol and cineole are two main components found in this essential oil which responsible for its toxicity. Toxic effects could include vomiting, diarrhea, hypersalivation, tremors, seizures or depression/depressed reflexes (give more details). At high dosages of exposure to this product, all these clinical signs might be observed. However, some other subclinical changes can also be observed such as increased liver enzymes levels on blood chemistry tests. A new study was conducted by Australian scientists to examine potential developmental effects of eucalyptus oil following prenatal exposure on rats. The main components of eucalyptus oil (eucalyptol and cineole) were shown to be teratogenic.

Short-term adverse effects of this product can be seen if the dogs are exposed by ingesting or smelling eucalyptus oil. Dogs might be affected after they accidentally chew on some leaves, bark, branch or even inhale the vapors of the essential oil. Generally, ingestion produces more severe clinical signs than inhalation since it is one of the common route for human to take in medications. However, dogs do not have same response with humans when it comes to taking medications orally as most medication that can be given orally cannot be absorbed effectively in dogs due to their physiology differences which result in dogs having short life spans compared to humans.
Signs of acute poisoning could be seen within minutes up to several hours after ingestion. Signs might include depression, vomiting, tremors, increased salivation (give more details). There are cases where the dogs die right away after exposure because the dogs were very sick. However, it has also been reported that some dogs can survive with supportive care which includes giving activated charcoal orally to bind the substance in the stomach and induce vomiting as well as giving intravenous fluids for dogs affected by tremors or seizures.
