Pet's info: Dog | Shiba Inu | Male | neutered | 35 lbs
35 lb dog ate mariguana chocolate edible, 5-15 gm THC, about the size of a 1/4 of a Hershey bar. Windstorm w/no electricity can’t get to an emergency clinic. Invested at about 5pm, still can’t get up, with waves of irrational heavy breathing. It’s really worrying me, anything I can do in the meantime? It was in a sealed air tight aluminum bag, put in my purse and managed to find it. Help Please??!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach!
Both chocolate and marijuana are toxic to dogs. The edible marijuana products can be the most toxic. The amount of chocolate is small and may or may not have caused the vomiting. The signs of marijuana toxicity are mostly neurological: drooling, uncoordinated, wobbly, dilated pupils, leaking urine, hyperactive, sedated, vocal or disoriented. In severe cases, tremors, seizures and coma can result. Fortunately, these side effects are usually short-lived but they can still be dangerous and make the pet quite miserable.
Treating this toxicity does include inducing vomiting but there are other life saving things that would be done: activated charcoal and supportive care until the drug has left the system.
If Stitch is no longer vomiting and is not showing any of the above symptoms he is likely fine. I would fast him for 12-24 hours and feed a blade diet for 2-3 days of boiled chicken or hamburger with rice. Feed 1 cup per 20 lbs per day. If he continues to vomit or is showing any of the above symptoms he should see a Vet and please be honest with what he he ate so they can help him.
I hope this helps and I wish Stitch the best!
