Welcome to another Monday edition in the infinitely long alphabet of plants your horse can’t eat. Today’s plant is one that may sound friendly, but Hound’s Tongue is one tongue your horse should never meet.
A Little About Hound’s Tongue
Cynoglossum or Hound’s Tongue is also called Wild Comfrey and Chinese Forget-me-not. This is a biennial that grows up to 4 feet tall. Leaves are tongue shaped and alternate up the stem. Flowers are red, purple or blue and grow at the end of the stem. Fruit is a pod covered with barbs.
How Dangerous Is It?
This plant is unpalatable to equines and generally only a threat during drought conditions. However it can be incorporated into hay so it is one horse owners should recognize. Hound’s Tongue contains pyrrolizidine alkaloids which can cause liver failure.
All parts of this plant are toxic (particularly so in the rosette stage) and can be fatal to equines.
What To Look For
You know your animal the best, so you should know when something is amiss. Hound’s Tongue toxicity symptoms are often called “walking disease” or “sleepy staggers” and include loss of appetite, weakness, yawning, diarrhea, photosensitivity, weight loss, los of coordination, jaundice, aimless walking and constant chewing motion.
