(AVMA) Miles was dying. The 12-year-old black Labrador Retriever–type dog had developed a splenic tumor that eventually metastasized to the liver and lungs. Miles was given two months to live and tramadol for the pain. But, Miles’ owner didn’t like the way tramadol affected her pet. “Every time we gave it to him, he would just sleep; he wouldn’t even move. He’d just lay there like he was dead,” said Denise, who asked that her real name not be used. Sitting outside a West Hollywood, Calif., café with Miles at her feet, Denise recalls how a friend suggested she try a glycerin tincture of marijuana that is sold as a pet medicine in dozens of licensed medical marijuana dispensaries throughout Los Angeles. Within an hour after she gave Miles the tincture, the dog’s appetite returned, and he was no longer vomiting. “It couldn’t have been a coincidence,” Denise said.
