Interesting....
I read the whole thread and did not find one fact on cannaboids and dogs.
I saw a bunch of hypothetical responses and some facts about chocolate and eatables.
Yes chocolate is poisonous to dogs, FACT. Yes dog's and cats have eaten chocolate and survived. (Had several trash diggers myself)
I know science has tested THC on rats and they do have receptors so one can assume all mammals do.
I would really like to see some supporting evidence on dogs and cannabis. They are one of the closest mammals to us. It would make sense that they have Cannaboid receptors. It exhibits in their behavior when ingestion.
Think about it if your world is a 3,000 sq foot plot; and you one day feel really weird. You'd shiver, piss yourself and lose balance too. That's nothing new for side effects. We are just aware of our decisions and anticipate it with excitement. We know what we are doing they don't.
I've been researching this subject for a while now my childhood dog "Whiskey" is nearing 15 years and has several tumors growing on her body. I am curious to know the possible benefits to heal some of these tumors and give her a more comfortable life.
Here are some interesting links one sounds like torture though.

Toxicity (Cut from above)
The median lethal dose (LD50) of oral THC in rats
was 800–1900 mg/kg depending on sex and strain [51].
There were no cases of death due to toxicity following
the maximum oral THC dose in dogs (up to 3000 mg/
kg THC) and monkeys (up to 9000 mg/kg THC) [51].
Acute fatal cases in humans have not been substantiated. However, myocardial infarction may be triggered by THC due to effects on circulation [52, 53]. This is unlikely to happen in healthy subjects but in persons with coronary heart disease for whom orthostatic hypotension or increased heart rate may pose a risk.
