Leonhart cited an article that appeared in USA Today saying that veterinarians in Colorado and Washington state are seeing an increase in the number of dogs needing treatment for exposure to marijuana.
"Again, it goes back to the edibles, it goes back to products that are in the household that are now made from marijuana, and it's impacting pets," Leonhart said. "We made a list of the outcomes we thought that might happen in these two states. We never thought of putting pets down."
Dogs usually don't eat marijuana by itself and marijuana isn't particularly harmful to dogs, but ingredients in edibles such as butter and chocolate can do significant damage to a dog's health.
Coloradans and Washingtonians should keep their pot brownies away from their pups.
