Can Dogs Have THC? | Understanding The Risks

THC is not the right choice for dogs, but hemp products with less than 0.3% THC content can still be beneficial and safe. There are serious risks for dogs that ingest THC.

THC, the psychoactive compound in cannabis, can be toxic to dogs, even in small amounts, causing symptoms like lethargy, vomiting, and in severe cases, seizures. While CBD is generally safe, it's important to ensure products are either THC-free or contain only trace amounts, as in full-spectrum CBD oils (below 0.3%).

Full-spectrum CBD is considered safe for dogs due to the minimal THC content and its enhanced effects when combined with other cannabinoids. Always consult your veterinarian before introducing any CBD product to your dog’s routine.

THC for Dogs: Safety Overview

THC (delta-9-tetrahydrocannabinol) is the main psychoactive compound in marijuana and one of the 113 cannabinoids found in cannabis plants. It affects a dog's body by interacting with the endocannabinoid system.

The psychoactive effects of THC stem from its ability to mimic natural endocannabinoids in the brain, disrupting normal neural communication and creating the well-known "high."

When considering THC oil for dogs, it's important to differentiate between the trace amounts of THC in hemp (0.3% or less) and concentrated THC oil.

While THC levels found in hemp are generally well-tolerated by dogs, higher concentrations in marijuana or THC oil can be toxic. Full-spectrum CBD oils that contain trace amounts of THC (below 0.3%) are considered safe for dogs.

Risks of THC Overdose in Dogs

Dogs have a higher concentration of cannabinoid receptors compared to humans, making them more sensitive to THC's effects. When exposed to THC, dogs can experience marijuana intoxication, which poses risks such as vomiting, lethargy, loss of coordination, and even seizures.

Accidental Ingestion: How to Prevent THC Poisoning in Dogs

Accidental THC ingestion can be dangerous for dogs. Common scenarios include:

  • Edibles: THC-infused foods like brownies or gummies contain doses that are unsafe for dogs. Always keep these products out of reach.
  • Discarded Marijuana Cigarettes: While walking your dog, be cautious of discarded cannabis cigarettes your pet may try to eat.
  • Improperly Stored Products: Cannabis oils, tinctures, and related items should be securely stored away from pets.
  • Secondhand Smoke Exposure: Exposure to cannabis smoke in enclosed areas can pose risks. Learn more.

Signs That Your Dog Ingested THC

If your dog ingests THC, look for these symptoms:

  • Unusual tiredness or unresponsiveness
  • Dilated pupils
  • Loss of bladder control
  • Difficulty walking or stumbling
  • Vomiting
  • Muscle twitching or shaking
  • Convulsions in severe cases

Symptoms may appear within minutes to hours and last for several days depending on the dose and dog size. Contact a veterinarian immediately if symptoms persist.

What Are Safer Alternatives to THC Oil for Dogs?

Since THC oil poses significant risks, there are safer alternatives that may provide benefits without the dangers of intoxication.

CBD Oil for Dogs

CBD (cannabidiol) is a non-psychoactive compound found in cannabis plants, including hemp. Used in products like CBD oil for dogs, it’s often combined with carrier oils such as MCT oil.

Research on CBD for dogs shows promising potential, with many pet owners reporting positive experiences. However, always consult a veterinarian before adding CBD to your dog's routine.

Hemp-Based Products

Hemp products contain less than 0.3% THC, making them safe for pets. Full-spectrum hemp oils include cannabinoids like CBD, terpenes, and flavonoids, which work together in what’s known as the entourage effect.

CBD isolates contain pure CBD without other plant compounds and may be preferred by those avoiding trace THC entirely.

Conclusion: THC Oil is a No-Go

THC oil is not safe for dogs. However, hemp-based and CBD products designed for pets may offer supportive benefits. Always consult your veterinarian when introducing CBD or hemp oil and monitor your dog’s response over time.
