Hi there-here is an article we wrote on the subject: https://www.hellomd.com/health-wellness/your-dog-ate-marijuana-what-to-do
It appears that canines may be more sensitive to the side effects of THC than felines. Eating cannabis flowers is not toxic per se; but dogs may exhibit symptoms of anxiety; fear and confusion if they become intoxicated with THC and its metabolites. Keeping a CBD rich tincture or oil product on hand is always a good idea. Small doses of CBD rich products can mitigate and reverse the effects of THC. Edible delivery can last many hours so you may have to dose the CBD more than once.
Symptoms will pass over time.
I would recommend you keep cannabis away from children and animals.
