Quick answer: Zesty Paws Advanced Calming Bites is the bigger formula on paper: nine actives, higher milligrams, including 60 mg of L-theanine and 50 mg of ashwagandha per chew. OcuLabs Calming + Anxiety Support Chews is the focused one: chamomile 80 mg, hemp seed oil 80 mg, valerian 50 mg, passion flower 30 mg, vitamin B1 30 mg, melatonin 4 mg and L-theanine 3 mg per two chews, no ashwagandha, ginger, tryptophan or magnesium, and a melatonin dose you can actually read. If you want maximum ingredients per chew at a shelf price, Zesty Paws. If your dog is a senior who paces at 6pm and cannot settle at night, and you want a short, disclosed, chicken-flavoured formula with a 90-day guarantee, OcuLabs.

What Zesty Paws does well
Breadth. The Advanced Calming Bites read like a survey of every calming ingredient with a study behind it: the GABA botanicals (chamomile, valerian, passionflower), the amino acids (L-theanine, tryptophan), an adaptogen (ashwagandha), a mineral (magnesium), a stomach settler (ginger), hemp and melatonin. The L-theanine dose in particular is the highest in the category. It is on every shelf and it is cheap per chew. For a young, robust, anxious dog whose owner wants to throw everything at the doorbell, it is a rational choice.
The trade-offs are stomach and specificity. Nine actives means nine things a sensitive senior gut has to tolerate, and ginger and ashwagandha are the two most likely to come back up. The melatonin is inside a blend, so you cannot dose it for sleep with any precision.
What OcuLabs does well
Focus and disclosure. OcuLabs Calming Chews are built for two moments: the 30 to 60 minutes before a predictable trigger, and the evening wind-down. Chamomile and valerian carry the botanical load, passion flower supports them, thiamine supports nerve function, hemp seed oil carries the fat-soluble actives, and melatonin sits at a printed 4 mg per serving, which is squarely in the range vets use for a mid-size dog's sleep rhythm. The formula is short on purpose, chicken-flavoured, free of corn, wheat, soy, colours and added sugar, and covered by a 90-day guarantee so you can run it for the full window before judging. It carries less L-theanine than Zesty Paws and no ashwagandha; if those are the ingredients you specifically want, that is a point for Zesty Paws.
Which one for your dog
- Senior dog, evening pacing, night restlessness: OcuLabs Calming Chews for the disclosed melatonin and valerian.
- Sensitive stomach: OcuLabs, the shorter list.
- Young dog, wants maximum actives per chew: Zesty Paws Advanced.
- Budget-first, buying at the pet store today: Zesty Paws.
- You want a refund window long enough to judge daily use: OcuLabs.
Either way: daily with food, and 30 to 60 minutes before the trigger, not during it. For what each ingredient does, read calming chews for dogs: ingredients explained; for the fast-acting clinical alternative, see OcuLabs vs VetriScience Composure.
