Safety status
What this means for your dog
Sudan grass is listed by the ASPCA as non-toxic to dogs — though its cyanogenic glycosides are dangerous to grazing livestock and horses, dogs don't typically eat enough to be at risk. A dog that chews on blades may vomit briefly or pass loose stool from the coarse fiber, nothing more.

Questions about Sudan Grass
Is Sudan Grass toxic to dogs?
Sudan Grass (Sorghum bicolor subsp. drummondii) is listed as non-toxic to dogs by the ASPCA. It is not expected to cause poisoning or serious harm if your dog chews or eats it.
What happens if my dog eats Sudan Grass?
No specific toxicity symptoms are expected. However, because Sudan Grass has fibrous stalks and long flat leaves, consuming a large amount may cause mild stomach upset such as vomiting or diarrhea. Monitor your dog and contact your vet if digestive symptoms persist.
What should I do if my dog ate a large amount of Sudan Grass?
Since Sudan Grass is non-toxic to dogs, an emergency response is not needed, but watch for signs of digestive discomfort like vomiting or lethargy after a large ingestion. If symptoms develop or persist, contact your veterinarian. For peace of mind, you can also reach the ASPCA Animal Poison Control Center at (888) 426-4435.
Can the fibrous texture of Sudan Grass cause problems for dogs?
The plant's fibrous stalks and leaves are not chemically harmful to dogs, but the physical bulk of the material can be hard to digest. Large quantities may lead to mild GI upset; non-toxic does not mean safe to eat in quantity, so discourage heavy grazing.
