General Information about THC, CBD,  and Metabolism in Dogs

When a dog ingests a cannabis edible, the time it takes for the cannabis to be metabolized and eliminated from the dog’s system can vary depending on several factors, such as:

• the amount ingested
• the size and weight of the dog
• the potency of the cannabis product

Generally, the effects of THC (tetrahydrocannabinol), the primary psychoactive compound in cannabis, can last anywhere from a few hours to over 24 hours. Generally, classic symptoms start with in 1 to 3 hours after exposure. However, in some cases, traces of THC can remain in the dog’s system for several days, especially if a large quantity is consumed.

Additional Details:

• Metabolism Rate: Dogs metabolize THC differently than humans, often more slowly, leading to prolonged effects. The elimination half-life of THC in dogs can range from 30 to 96 hours, meaning it can take several days for the substance to be completely cleared from the dog’s system.
• Liver and Fat Storage: THC is highly lipophilic, meaning it binds to fat tissues in the body. As a result, it may take longer for THC to be released from fat stores and metabolized by the liver. This process can extend the duration of intoxication and the time needed for the substance to be eliminated.
• Symptoms Duration: Depending on the dose, symptoms of cannabis toxicity, such as depression of central nervous system, lethargy, uncoordinated movements, and urinary incontinence, may persist for 12-24 hours, and in severe cases, longer.

Key Statistics:

1. 80% of dogs show symptoms of cannabis toxicity within 30-60 minutes of ingestion.
2. 15-30% of dogs may experience prolonged effects lasting more than 24 hours, particularly if they consume a high dose.
3. In cases of severe cannabis toxicity, 1-2% of affected dogs may require hospitalization for more than 48 hours for supportive care and monitoring.

Understanding the timeline and factors influencing the metabolism of cannabis in dogs is crucial for pet owners and veterinarians to provide appropriate care and ensure a safe recovery.

THC vs. CBD in Dogs

THC is the primary psychoactive compound in cannabis, responsible for the “high” effect. It can be toxic to dogs even in small amounts because dogs have more cannabinoid receptors in their brains than humans, making them more sensitive to the effects of THC.

CBD, on the other hand, is a non-psychoactive compound that is often used for its potential therapeutic effects, such as reducing anxiety, pain, and inflammation. Unlike THC, CBD is generally considered safe for dogs when administered in appropriate doses.  However, there are not enough studies suggesting safe dose recommendations in dogs. Therefore, It is strictly advised to consult a veterinarian before administering to dogs.

Effects of CBD on Dogs

• Therapeutic Uses: CBD is often used to help manage conditions like arthritis, anxiety, seizures, and chronic pain in dogs. It is not associated with the psychoactive effects that THC produces.
• Safety Profile:
• The safety profile of CBD is not yet fully determined because there is not enough research available. However, it does show an improvement in Arthritis pain, seizures and anxiety with no observable side effects on therapeutic dosage. In contrast, It can cause an elevation in liver enzymes and can have side effects such as vomiting, diarrhoea, slow or fast heart rate and rapid breathing. Therefore a veterinary consultation is recommended before giving to your dog.
• Metabolism: CBD is also metabolized in the liver but does not bind to fat tissues like THC, meaning it is cleared from the body more quickly and with fewer side effects.

Comparing Toxicity

• THC Toxicity: Even a small amount of THC can cause serious side effects in dogs, including ataxia (loss of coordination), hyperesthesia (heightened sensitivity), incontinence, and in severe cases, coma or death. The duration of THC effects can last from several hours to days, depending on the dose.
• CBD Toxicity: CBD does not produce the same toxic effects as THC. High doses of CBD might cause lethargy, diarrhea, or changes in appetite, but these effects are usually mild and short-lived.

Key Points to Remember

• Dosage Matters: Both THC and CBD should not be used in dogs without having proper veterinary guidance.Although CBD is considered safe, it is still advisable to follow your veterinarian’s instructions on CBD oil usage.
• Vigilance: Always keep THC products, including edibles, out of reach of pets. While CBD products are generally safer, they should also be stored securely and used according to veterinary guidance.

Conclusion

While CBD is much safer for dogs than THC and is used for various therapeutic purposes, pet owners should always consult with a veterinarian before administering any cannabis-derived products to ensure safety and proper dosing.
