Dogs, too, can be harmed by essential oils. However, most agree using non-toxic essential oils in a diffuser for a short period of time is not likely to be an issue, although diffusers should not be used if the pet has breathing problems, is confined to a small space and cannot leave, or a lot of oil is being used.

Can dogs be in a room with a diffuser?
