Get Your Medical Marijuana Card Today - Fast & Easy!

If you’ve been prescribed medical cannabis for anxiety or another medical issue, you’ll need to keep your supply safe from some members of your household—including your pets.
While cannabis is only toxic to dogs in massive quantities, it can still negatively affect them. In addition, some ingredients found in cannabis edibles and smokables can be toxic to dogs. All in all, keeping your stash away from your dog is a wise choice.
But what happens if your dog does break into your supply of medical marijuana? In this guide, we’re breaking down everything pet parents need to know about the toxicity of marijuana to dogs, steps to take to treat your dog, and tips for keeping your supply safe in the future.
Yes, marijuana can be toxic to dogs. But, like humans, dogs need to ingest an impractically large dose of THC to even scratch the surface of fatal health threats.
A lethal dose of THC for dogs is approximately 3 grams per kilogram of body weight. Here’s a quick table of minimum lethal doses for dogs of various body weights:
| Body weight (lb) | Body weight (kg) | Minimum lethal THC dose (g) |
|---|---|---|
| 10 | 4.5 | 13.5 |
| 20 | 9.0 | 27.0 |
| 30 | 13.6 | 40.8 |
| 40 | 18.1 | 54.3 |
| 50 | 22.7 | 68.1 |
| 60 | 27.2 | 81.6 |
It’s important to note that these lethal doses are:
This should put you at ease—unless your dog ate an incredibly large volume of cannabis.
Even if you’re confident that your dog didn’t consume a potentially lethal dose of marijuana, you should still take a few steps to care for them.
First, pay close attention to your dog’s behavior. After your dog eats cannabis, you may note symptoms like:
Most of these are benign, but there are certainly symptoms that might indicate intense distress. If you notice any of the following, contact your vet right away:
If your dog experiences any of the above symptoms, your vet will likely treat them with IV fluids, seizure medications, and anti-anxiety drugs, respectively.
Instead of taking your eyes off of your dog to write down their symptoms, consider using tools that will make it easier to supervise your dog, like your smartphone’s:
This documentation will help your vet determine what kinds of treatment your dog needs, if any.
While THC and cannabis are only toxic to dogs in very high doses, there are two other ingredients to watch out for if your dog breaks into your stash:
In most cases, nicotine ingestion is much more dangerous for dogs than chocolate ingestion, especially in the context of cannabis products. Nicotine can be toxic to dogs in doses as low as 9 to 12 mg/kg of body weight—the average cigarette contains 12 mg of nicotine. So, just one blunt or spliff could put your dog’s health in jeopardy.
Theobromine, on the other hand, rarely poses fatal toxicity concerns for dogs. Plus, you’ll only find dangerous levels of theobromine in high-quality baker’s chocolate or dark chocolate; white chocolates and artificially flavored chocolate products pose very low risks.
Nonetheless, you should do your best to determine which kinds of cannabis products your dog ate—this will help you communicate with your vet.
After recording your dog’s symptoms and doing some quick investigating, it’s time to call the vet—even if your dog isn’t showing many symptoms or there aren’t any toxic ingredients in your cannabis supply.
Why call the vet even if you’re not concerned about toxicity or fatality?
Your vet may tell you that it’s safe to remain at home with your pet; we’ll break down how to care for your pet at home in the next section. If they ask you to come in, head to the clinic as soon as possible.

The effects of the high should wear off in a few hours. Once your dog has recovered, make food and water available and do what you can to encourage eating and drinking.
As your dog recovers, start thinking about what you can do to keep both your pet and your supply safe in the future. We recommend:
In addition, consider choosing cannabis products without ingredients that are toxic to dogs to mitigate risks as much as possible; opt for nicotine-free smokeables and chocolate-free edibles on your next dispensaries trip.
If you’ve been prescribed medical marijuana for back pain or any other health issue, keeping your supply out of your dog’s paws (and mouth) is a must—safe storage and kennelling are two options that will help you keep your pet safe from potential incidents.
