Dogs are “very curious” and “indiscriminate eaters,” which means they’re more likely to wolf down a discarded joint, get into a bag marijuana flowers or gobble an edible, Laura Stern, a veterinarian with the ASPCA Animal Poison Control Center, told NBC News via email.

“We have seen a significant increase in the number of calls we have received about pets and marijuana,” said Stern.

Cats can also be harmed by marijuana, usually by exposure to second-hand smoke, but about 90 percent of the marijuana-related calls to the Animal Poison Control are about dogs, said Stern.
