Hydra Rituals Serum-1.76oz.

My anxious dog actually settled down during a storm after I applied this—the chamomile and eucalyptus mix is noticeably soothing. The 1.76oz bottle lasts longer than I expected for daily use.

The lavender and cedar combo is so gentle, not at all overpowering, and my cat actually sat still for a full brushing session after I used it. A tiny bit goes a long way on her coat, and she seems noticeably calmer come bedtime.

The lavender and chamomile in this actually seem to do something, because my dog settles on his bed within minutes of me rubbing a few drops into his coat. It doesn't leave a greasy residue either, which I was worried about with an oil.
