Brian Haag of California was concerned when his puppy, Phyllis, started shaking and was having trouble standing up straight. He had no idea why and took her to the vet.

Brian says while he doesn’t use marijuana, he shares a yard with neighbors who do and he believes Phyllis may have eaten a discarded joint.
