Q. Who is Mr. Smarty Plants?
A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.
Did you know you can access the Native Plant Information Network with your web-enabled smartphone?
Ask Mr. Smarty Plants is a free service provided by the staff and volunteers at the Lady Bird Johnson Wildflower Center.

Title: Are Chilean Mesquite pods poisonous to dogs?
Answered by: Jimmy Mills
QUESTION:
Are chilean Mesquite tree pods poisonous to dogs?ANSWER:
When we get questions about plants toxic to animals, there are several databases listed below that we regularly consult.
Poisonous Plants of North Carolina
Cornell University Plants Poisonous to Livestock
University of Pennsylvania Poisonous Plants
Canadian Poisonous Plants Information System
The ASPCA has a list specific to dogs; Toxic and Non-toxic Plant List—Dogs.
Checking these databases reveals no record of the genus Prosopis being toxic to dogs. The Chilean mesquite, Prosopis chilensis, however is a non-native species, so it may not be listed in the sources above. On the other hand, mesquite beans have been harvested and ground for flour for human consumption for years. In addition, tucked away in this article "Mesquite Trees in Arizona" is the factoid that in the late summer and fall, 80% of a coyote's diet may consist of mesquite beans.
From all of this, I would conclude that Chilean mesquite beans are probably not toxic to dogs.
