Dog ate cannabis and THC products? What to do
THC from cannabis makes dogs wobbly, sleepy or jumpy and can cause leaking urine. Concentrated edibles can be more serious.
If your dog ate or touched this, call your vet or a pet poison line now

- Startling at sound or movement
- Trembling
- Slow heart rate

Why
There is no safe amount of psychoactive THC for dogs, and dogs have many cannabinoid receptors in their brains. Deaths are rare but have followed highly concentrated products.
