Dogs can react strongly to situations that seem ordinary to people. Thunderstorms, fireworks, unfamiliar places, car rides, visitors, and changes in household routines can lead to pacing, whining, hiding, barking, panting, or other unusual behavior. Before choosing a supplement, the reason for the behavior deserves attention because anxiety-like signs can sometimes occur alongside pain or illness.
Interest in Holistapet CBD Calming Chews for Dogs has grown as pet owners have become more familiar with hemp-derived products. Chews are especially appealing because they are simple to administer and resemble ordinary treats. Still, convenience does not establish effectiveness, and current veterinary research does not support treating CBD as a proven solution for every form of canine anxiety.
Understanding CBD in Dog Chews
CBD, or cannabidiol, is one of the compounds found in cannabis plants. Unlike THC, CBD does not produce the intoxicating effect commonly associated with marijuana. Hemp can be used as a source of CBD, although hemp-derived products may contain other cannabinoids depending on the manufacturing process.
Dog chews usually combine CBD with a food-based formula. The remaining ingredients can include oils, proteins, starches, flavorings, vitamins, minerals, or botanical extracts. That means the complete ingredient list matters just as much as the CBD claim on the front of the package.
The U.S. Food and Drug Administration has not approved cannabis or CBD products for treating medical conditions in animals. The agency has also raised concerns about product quality, safety, labeling accuracy, and possible interactions with medications.
Why formulation matters
A CBD oil and a CBD chew may contain the same advertised amount of CBD while producing different exposure in the body. Research published in 2025 compared CBD oil and treat formulations in dogs and found differences in pharmacokinetic measurements between the two forms.
That finding matters when comparing products. A milligram number printed on a package describes the stated amount in the product, but it does not necessarily tell how much CBD reaches the dog’s bloodstream.
What Research Says About Calming Effects
Research into CBD and dogs has increased, but the evidence is uneven. A 2023 review published in Frontiers in Veterinary Science examined available canine research and found that many studies focused on osteoarthritis, pain, pharmacokinetics, and tolerability. Considerably fewer studies examined behavioral disorders.
This distinction is easy to miss when reading commercial descriptions. Evidence that CBD may influence pain or mobility does not automatically prove that a chew can treat separation anxiety, noise phobia, or generalized nervousness.
A quieter dog may also be difficult to interpret. Reduced movement could mean that a dog feels less distressed, but it could also indicate drowsiness or another physiological effect.
What a responsible assessment looks like
A useful evaluation should consider several factors rather than relying on one observation:
- The situation that caused the dog’s behavior.
- How frequently the behavior occurs.
- How long each episode lasts.
- Whether physical symptoms appear at the same time.
- The dog’s age and general health.
- Current medications and supplements.
- The exact CBD amount in the product.
- Other active ingredients in the chew.
- Whether independent laboratory testing is available.
A simple record can be helpful. Write down the date, situation, behavior, product given, time of administration, food intake, and any noticeable changes. Patterns may become easier to identify after several observations.
Choosing a CBD Chew Carefully
The label should be clear enough to show exactly what is being administered. A product that simply advertises a “hemp blend” gives less useful information than one that identifies the amount of CBD per individual serving.
Look for:
- CBD amount per chew.
- Total CBD amount per container.
- Complete ingredient list.
- THC information.
- Batch or lot number.
- Laboratory testing that corresponds to the batch.
- Manufacturer contact information.
- Storage instructions.
- Expiration or best-use information.
A certificate of analysis can be useful when it comes from an independent laboratory and identifies the specific batch. It may provide information about cannabinoid concentrations and certain contaminants.
Laboratory testing, however, is not the same as FDA approval. A product can have a laboratory report without having been evaluated or approved as a treatment for canine anxiety.
Pay attention to the other ingredients
CBD often receives most of the attention, but the rest of the chew can affect whether the product is suitable for a particular dog.
Dogs with food allergies may react to proteins or flavoring ingredients. Dogs with certain medical conditions may require dietary restrictions. Products containing multiple botanical compounds can also make it harder to identify which ingredient caused an unwanted response.
Xylitol deserves special attention. The FDA identifies xylitol as a substance that can be dangerous to dogs. Any canine product should be checked carefully for potentially harmful sweeteners or other unsuitable ingredients.
Safety and Possible Side Effects
Research has provided some information about CBD tolerability in dogs, but long-term safety questions remain. A 2024 study examined healthy beagles receiving cannabinoid preparations over 90 days and reported that the tested preparations were tolerated under the study conditions.
The study does not establish that every commercial CBD chew will behave the same way. The dogs were healthy, the formulation was controlled, and the research dose was specific to the experiment.
Another study reported increased CBD exposure after repeated administration and identified gastrointestinal effects at a higher tested dose. These findings reinforce the need to avoid treating a research dose as a universal recommendation.
The FDA has reported possible adverse effects associated with cannabis exposure in pets, including lethargy, depression, excessive drooling, vomiting, agitation, tremors, and convulsions.
Dogs requiring extra caution
Veterinary advice is especially appropriate when a dog:
- Takes prescription medication.
- Has liver or kidney disease.
- Has a seizure disorder.
- Has a history of gastrointestinal problems.
- Is elderly with multiple health conditions.
- Has unexplained changes in behavior.
- Has previously reacted to cannabis products.
- Is scheduled for anesthesia or sedation.
CBD may interact with other medicines. A veterinarian can review the dog’s medication list and determine whether introducing a cannabinoid product creates an avoidable risk.
Managing Stress Beyond Supplements
A calming chew should not be considered the entire behavior plan. The environment often has a major effect on how a dog responds to stressful situations.
For thunderstorms or fireworks, a quiet interior room, closed curtains, familiar bedding, and steady background noise may reduce exposure to frightening sounds. Some dogs also benefit from gradual desensitization and counterconditioning conducted under appropriate behavioral guidance.
Car anxiety may require shorter practice trips, secure restraint, and gradual exposure. Separation-related behavior can require a structured training plan.
The cause matters.
A dog that becomes anxious only during fireworks needs a different approach from a dog that suddenly begins pacing every evening. The second situation may warrant a medical evaluation before a supplement is considered.
Understanding the Pet Supplement Market
Pet supplements have become a significant consumer category. The American Pet Products Association reported that 53% of U.S. dog-owning households gave their dogs vitamins or supplements in 2024. APPA also reported that the U.S. pet industry reached approximately $158 billion in spending in 2025.
Those figures describe consumer behavior and overall pet spending. They do not prove that CBD products work for canine anxiety.
Market growth and clinical evidence answer different questions. A product can become popular while research is still developing.
Final Thoughts
CBD research in dogs continues to expand, but evidence for using CBD specifically to calm anxious dogs remains limited. Product transparency, veterinary guidance, ingredient safety, and careful observation provide a more responsible basis for considering these chews.
