Stinking chamomile or Anthemis Cotula, also called stinking mayweed and dog’s fennel, is a foul-smelling plant that is a part of the sunflower family. A bushy annual, this plant will produce pretty, yellow flowers that are about three-quarters to one inch in diameter. Surrounding these yellow parts are 12 to 20 white ray flowers. Seen throughout most of the United States, at its maturity, the plant will stand between 12 and 24 inches tall and have hairless stems branching from it. The plant has no positive use and can be harmful to humans and animals. It is often found growing along roads and in fields, in particular where irrigation is present for farming. The United States Department of Agriculture has declared it a noxious weed due to its invasiveness.
Stinking chamomile is considered toxic for pets with a variety of substances that could hurt your dog. Fortunately, should your dog make contact with or consume a portion of the plant, he will experience irritating but not deadly results. Due to the irritant substances that impact the skin and mucous membranes, along with its unpleasant smell and taste, animals rarely ingest much of it.
Also known as stinking mayweed and dog’s fennel, stinking chamomile is a foul-smelling, foul-tasting plant that is toxic to your dog if ingested, causing gastrointestinal upset.
