Are essential oil diffusers toxic to dogs? How much risk?
It's really hard to say as each individual pet is going to have different susceptibility to the item, and how much you use the diffuser/what oils are placed in it can also affected this. That said, it is always best to err on the side of caution. If you need to use your diffuser at night, keeping Nugget in a different room while you do, or making sure the room is well-ventilated can help.
If you notice any signs of an issue such as Nugget coughing or wheezing, running nose, changes in behavior, lethargy, confusion, etc, it is best to move her to a well-ventilated room ASAP. A visit to your vet, especially if you notice any longer lasting changes, is also a good idea to make sure there is no issue.
