Now that 24 states have legalized the recreational use of marijuana, many people have access to cannabis products. But when it comes to dogs, THC —  the psychoactive agent in cannabis — doesn’t produce a high. It just makes them sick.

Put simply, any amount of THC is toxic to dogs. It targets their nervous system, causing characteristic signs within an hour of ingestion. Even a small amount of THC can cause a dog to stumble, shake, urinate inappropriately or much worse. Keep in mind that some cannabis products contain up to 90 percent THC.

If your dog shows any abnormal signs that you suspect are due to cannabis ingestion, bring them to a veterinary clinic right away. Make sure to tell the veterinary team exactly what your pooch may have eaten so that they can provide the best care.
