Has your dog ever gotten into something they shouldn’t have, leaving you worried and unsure what to do? As marijuana becomes more common in households, accidental ingestion by pets is increasingly reported. It’s natural to wonder: can dogs get high, and what happens if they do? Let’s break it down so you can better understand the effects of marijuana on dogs and how to keep your furry friend safe.

⚠️ What to Watch For

If your dog consumes marijuana, either by eating cannabis products or inhaling second-hand smoke, you may notice some unusual behaviors or symptoms. Dogs are much more sensitive to THC (the psychoactive compound in marijuana) than humans, which means even small amounts can lead to significant effects.

Common signs of marijuana toxicity in dogs include:

  • Lethargy or extreme sedation
  • Loss of coordination (stumbling or difficulty walking)
  • Drooling or vomiting
  • Glassy eyes or dilated pupils
  • Urinary incontinence
  • Changes in heart rate (either faster or slower)
  • Tremors or seizures (in severe cases)

Symptoms can begin within 30 minutes to a few hours of ingestion and may last for several hours, depending on the dose and your dog’s size. If you notice any of these signs, it’s crucial to act quickly.

🔍 Possible Causes

Dogs can be exposed to marijuana in several ways. While edible products like cannabis-infused brownies or gummies are the most common culprits, second-hand smoke or discarded marijuana buds can also pose risks. Some pet owners may even mistakenly think giving marijuana to their pet will help with anxiety or pain, not realizing the potential harm.

It’s important to understand that THC, the psychoactive component in marijuana, is toxic to dogs. Unlike humans, dogs’ bodies process THC differently, making them more susceptible to its negative effects. Even CBD products, which are derived from cannabis but lack the psychoactive properties of THC, should be used cautiously and only under veterinary guidance.

✅ What You Can Do at Home

If you suspect your dog has ingested marijuana, the first step is to stay calm and assess the situation. Here’s what you can do:

  • Determine how much your dog may have consumed and what type of product it was (edible, flower, oil, etc.). This information will be crucial for your vet.
  • Remove any remaining marijuana or cannabis products from your dog’s reach to prevent further ingestion.
  • Monitor your dog closely for symptoms like lethargy, vomiting, or difficulty walking.

While mild cases of marijuana ingestion may resolve on their own with time, you should always consult a veterinarian to ensure your dog receives the care they need. Never try to induce vomiting without veterinary guidance, as this can sometimes worsen the situation.

💡 When to Call a Vet

It’s always a good idea to contact your veterinarian if your dog has been exposed to marijuana, even if they seem fine. In some cases, marijuana toxicity can cause severe or life-threatening symptoms, such as tremors, seizures, or dangerously low blood pressure.

Seek emergency veterinary care immediately if your dog:

  • Is unresponsive or extremely lethargic
  • Has difficulty breathing
  • Experiences tremors or seizures
  • Shows signs of severe vomiting or dehydration

Your veterinarian may perform tests, such as bloodwork or urine analysis, to confirm marijuana exposure and rule out other potential causes of your dog’s symptoms. Treatment typically involves supportive care, such as IV fluids, anti-nausea medication, and monitoring, to help your dog recover safely.

🩺 Vet Recommendations

Preventing marijuana exposure is the best way to protect your dog. Here are some tips to keep your pet safe:

  • Store all cannabis products, including edibles, oils, and flower, in secure containers out of your dog’s reach.
  • Avoid smoking marijuana near your pet, as second-hand smoke can still affect them.
  • If you use CBD products for your pet, choose veterinary-approved options and consult your vet for proper dosing.

Remember, marijuana is not safe for pets, and even small amounts can cause serious health issues. By taking precautions, you can reduce the risk of accidental exposure and keep your dog happy and healthy.

FAQs

Q: Can my dog die from eating marijuana?
A: While it’s rare, severe marijuana toxicity can be life-threatening, especially if your dog ingests a large amount or a product containing high levels of THC. Always seek veterinary care if you suspect your dog has consumed marijuana.

Q: Can CBD products harm my dog?
A: CBD is generally considered safe for dogs when used appropriately, but it’s important to choose veterinary-approved products and consult your vet for guidance. Avoid CBD products that contain THC, as these can be toxic to pets.
