Taking A Closer Look At Hemp CBD

Until now, Mud Bay did not stock any full-spectrum hemp products or isolates for two main reasons:

1. The legalities and regulations around these types of products were unclear and highly debated.

2. The legal ambiguity also limited the amount of peer-reviewed research about the effects of hemp extract products on companion animals.


When the 2018 Farm Bill formally defined industrial hemp and made its derivatives federally legal, it eliminated our two biggest concerns. Simultaneously, many researchers were publishing peer-reviewed case studies showing the safety and efficacy of such products in companion animals. These changes allowed our on staff Veterinarian and Category Manager to confidently recommend stocking this federally legal product that has valid scientific research investigating its efficacy and safety.

For pet owners who have made the personal decision to use a CBD oil supplement for their dog or cat, some best practices must be followed to reduce the risk of toxicity. This risk comes from THC, as well as other potentially harmful ingredients absorbed during plant cultivation or while extracting the oil from the hemp. 

  1. Minimal THC Guarantee: There are no valid reasons to give your pet any product that contains THC levels above 0.3% unless under the supervision of your veterinarian. THC can be toxic to some animals, and both dogs and cats show signs of toxicity. Dogs are particularly sensitive to THC. Any company producing CBD oil for pets should conduct independent lab testing that indicates it contains THC well below 0.3%.

    We highly recommend that pet parents avoid buying CBD products from dispensaries, as it can be hard to tell if the product comes from Industrial Hemp or Marijuana and if it would contain THC in concentrations higher than what is recommended.

  2. Certificate of Analysis: A Certificate of Analysis should be available for every batch of a product that enters a manufacturing plant. Also, verify certificates match the final product lots that you buy. It’s not uncommon for companies to sell diluted products that contain only a fraction of the cited CBD input. Never buy products without a lot number and expiration date.

  3. Certified Organic: Because Cannabis sativa L. is a bio accumulator, it stores substances in its leaves, such as pesticides, heavy metals and other chemicals, faster than it excretes them. Therefore, it’s worth buying a product made from certified organic hemp, and you should ask the manufacturer if the company tests for heavy metal contamination, pesticide residue, and CBD concentration.

  4. Full-spectrum Products: There’s evidence that the chemical compounds in a full-spectrum product work together in ways that haven’t been fully identified. In human studies, the full-spectrum products seem to work better than an isolate that has only one phytocannabinoid. In addition to the 70 phytocannabinoids in marijuana (the two most commonly discussed are THC and CBD), there are 140 different terpenes and terpenoids that can alter mood and offer analgesic effects. Interactions between hundreds of the unique compounds contained in a product may amplify positive effects or minimize negative ones.

  5. Tinctures: For pets, tinctures offer the best bioavailability. Tinctures are liquid preparations that are designed to be placed in the cheek pouch or under the tongue. This positioning allows your dog or cat’s body to absorb the CBD orally before it enters the digestive tract. A tincture is ideal for systemic CBD use to help reduce symptoms of epilepsy, anxiety, generalized dermatitis or arthritis.

  6. Treats: When the CBD is ingested with food—such as being part of an edible—preliminary experiments have demonstrated that CBD is barely absorbed into the bloodstream. These products are recommended as a nutritional supplement but not as the first choice if a specific effect is desired.
