Is Chinaberry Toxic to Dogs?

Chinaberry (Melia azedarach) is an invasive non-native tree common in older Texas neighborhoods and abandoned lots, and the ASPCA Animal Poison Control Center plant database lists it as toxic to dogs, cats, and livestock. The fruit (small yellow berries that ripen in late fall and persist into winter) is the most concentrated source of the toxic compounds (meliatoxins, tetranortriterpenes).

Symptoms of Chinaberry ingestion: vomiting, diarrhea (sometimes bloody), weakness, seizures, and respiratory failure in severe cases. The Merck Veterinary Manual cites cases where as few as 6-8 berries caused fatal poisoning in small dogs. Symptoms can be delayed several hours, which makes ingestion easy to miss. Call the ASPCA at (888) 426-4435 if your dog may have eaten the berries.

Chinaberry is also classified as an invasive species by the Texas Invasive Species Institute, so removing it serves both pet safety and ecological purposes. The tree drops large quantities of berries in fall and winter, and dogs find them while sniffing around the yard. The berries are also attractive to children.

Safe native alternative: Mexican Plum (Prunus mexicana). White spring blooms, small edible fruit (safe for humans and birds), great fall color, native to most of Texas, and not on the ASPCA toxic plant list. If you have a Chinaberry tree in a yard with pets, removal is the recommended path. While the tree is in place, rake fallen berries weekly during the fall and winter drop season.
