When properly extracted, most CBD oil for animals and humans should be highly similar. Both types should have high purity, come from organic cannabis plants (ideally, hemp), and have zero or micro amounts of the psychoactive cannabinoid, THC.
What’s the difference?
THC and dogs
Carrier oils aside, it seems like the main issue with human CBD oil is it’s higher THC content. While not necessarily harmful, dogs and THC do not mix well. If your dog does happen to ingest the psychoactive cannabinoid, expect to see symptoms ranging from confusion, anxiety, and paranoia, to discoordination, drunkenness, and lethargy. More serious reactions have also been recording, including tremors and seizures in rare cases.
