Our Calming Collars use aromatherapy. The scent of our carefully selected herbal blends has been tested for effectiveness with both dogs and cats. We use only real dried herbs, never essential oils or unnecessary fillers. The specific herbs used are listed on each product page. As your dog or cat smells the natural herbal blend, they often become more relaxed and less stressed.

Our collars are sized by your pet's neck measurement, not by breed. For the best fit, we recommend measuring your dog or cat's neck rather than guessing.

Measure loosely so the collar fits comfortably. Because our collars are filled with herbs, they fit differently than a standard flat collar. If your pet falls between two sizes, we recommend ordering the larger size. This allows for additional herbs and a more comfortable fit.

You can also include your pet's exact neck measurement in the Special Instructions box during checkout, and we'll tailor the collar for the best possible fit.

Most pets do well with our standard two-row (two-channel) collar.

We also offer a single-row version, a standard two-row version, and an extra-wide four-row version. Watching our comparison video is the easiest way to see the differences between each style.

For most cats and smaller dogs, we recommend the single-row width.

The lifespan of the herbs depends largely on how often they're exposed to air.

If your pet wears the collar 24/7, the herbs typically remain effective for about 3 to 4 months. If the collar is worn only occasionally and stored in a sealed plastic bag in a cool, dark place when not in use, the herbs may last a year or even longer.

Many customers who use their collars primarily during storm season simply purchase a new one each year. You can also gently roll the collar between your hands to lightly crush the herbs, helping refresh the scent and release more of their natural oils.

Yes. Many of our customers leave the collar on their pets around the clock.

The only downside is that continuous exposure to air causes the herbs to lose their scent more quickly, so you can generally expect about 3 to 4 months of use when worn full time.
