This pilot study explored the potential of microdosing 1-cyclopropionyl-d-lysergic acid diethylamide (1cp-LSD) to treat canine anxiety. A single-case study was conducted on a 13-year-old female dog with severe separation anxiety, who was treated with 5 µg of 1cp-LSD every 3 days for a month. Anxiety was assessed before, after, and 1 month following treatment using a validated questionnaire. The...

Anxiety affects 14-20% of dogs. Pharmacological treatments often fail. Psychedelics have shown to be useful for anxiety and depression in humans, but their veterinary use remains unexplored. We aimed to determine the effects of low-dose 1-cyclopropionyl-d-lysergic acid diethylamide (1cp-LSD) administered in a single dose to a dog, to observe the effect and establish the safety of the substance....
