VETRISCIENCE Composure Calming Chews offer a unique blend of calming ingredients, including colostrum, L-theanine, and vitamin B1, specifically designed to address stress in dogs. These chews are particularly effective for situations like storms or separation anxiety, as they are clinically proven to work within 30 minutes and provide relief for up to 4 hours. This quick response time makes them a favorite in veterinary clinics, which speaks to their credibility and effectiveness.

One of the standout features is the product's commitment to safety. The chews are made from high-quality ingredients, free from artificial additives or preservatives, and are certified by the National Animal Supplement Council. Additionally, the formulation has been developed by veterinarians, ensuring that it meets high standards for pet health.

The peanut butter flavor makes it appealing for most dogs, encouraging them to consume the chews willingly. For pet owners, the ability to administer them daily or as needed, with the option to double or triple the dose during highly stressful situations, adds a layer of convenience. There are some drawbacks to consider, as the chews are primarily marketed for dogs up to a certain weight, which may limit their use for larger breeds without adjusting the dosage. Results can vary depending on the individual dog's temperament and specific anxiety triggers, and some users may find the need for additional behavioral training alongside the chews for optimal results.

One of its standout features is the liposomal delivery system, which enhances nutrient absorption significantly, ensuring that your pets get the maximum benefit from the colostrum. The colostrum is rich in immunoglobulins (at least 25%), growth factors, and enzymes, which can support immune and digestive health, as well as improve the condition of your pet's coat. This product is suitable for pets of all ages, from young ones needing immune support to older pets with gut and allergy issues.

The liver flavor may appeal to pets, making it easier to administer the powder. Additionally, the product comes with a one-year money-back guarantee, reflecting the manufacturer's confidence in its efficacy. On the downside, the product’s effectiveness may vary for individual pets.

Moreover, while the brand has a good reputation, it is always advisable to consult with a veterinarian before starting any new supplement regimen for your pet.
