You are in the pet aisle with a tub of Zesty Paws Calming Bites in one hand and the OcuLabs page open on your phone. Here is what sets them apart, and which one is built for the dog waiting at home.
Quick answer: OcuLabs Calming + Anxiety Support Chews print every active with its own amount, including melatonin 4 mg and valerian root 50 mg per two chews, so you know exactly what your dog gets for the evening wind-down. Zesty Paws Advanced Calming Bites list valerian and melatonin inside a relaxation blend, with no separate figure for either. For a senior who paces at dusk, a dog with a touchy stomach, or anyone who wants to read the dose, OcuLabs is the better fit.
What is in OcuLabs Calming Chews
Per two chews: chamomile extract 80 mg, hemp seed oil 80 mg (not CBD), valerian root 50 mg, passion flower extract 30 mg, vitamin B1 (thiamine) 30 mg, melatonin 4 mg, L-theanine 3 mg. Seven named actives, each with its amount, in a chicken-flavoured soft chew.
Where OcuLabs comes out ahead
- Melatonin you can read: OcuLabs 4 mg, printed. Zesty Paws: inside a blend, no figure.
- Valerian you can read: OcuLabs 50 mg, listed on its own. Zesty Paws: inside the same blend.
- Every amount printed: OcuLabs lists all seven actives with their milligrams, nothing in a blend.
- Clean list: OcuLabs has zero corn, wheat, soy, artificial colours or added sugar. Zesty Paws: check the current label.
- Guarantee: OcuLabs covers your first purchase for 90 days, empty jar included. Zesty Paws: the retailer's policy.
Why OcuLabs is the better fit for most anxious dogs
You can read the dose that matters at night. OcuLabs Calming Chews are built for two moments: the 30 to 60 minutes before a predictable trigger, and the evening wind-down. Melatonin sits at a printed 4 mg per two chews, inside the range vets commonly use (about 1 mg for small dogs up to 3 to 6 mg for large dogs), next to valerian root 50 mg. With a blend, you are guessing.
A short list on purpose. Chamomile and valerian carry the calming load, passion flower supports them, thiamine supports normal nerve function and hemp seed oil adds omega-rich wellness support. Fewer actives means less for a sensitive senior stomach to handle, and if something does not agree with your dog, a short list is easier to troubleshoot.
Your dog stays themselves. The formula is non-sedating, so your dog settles, startles less and still eats, plays and meets you at the door.
A real window to judge it. Calmer evenings build with daily use, so the 90-day guarantee on your first purchase gives you time to see the change before you decide.

Choose OcuLabs Calming Chews if
- Your dog is a senior who paces as the light goes and cannot settle at night.
- Your dog has a sensitive stomach and you want the short list.
- You want to know the exact melatonin and valerian your dog gets.
- You want a refund window long enough to judge daily use.
How to start this week
- Pick one chew, not two. These formulas overlap on chamomile, valerian, passion flower, hemp, L-theanine and melatonin, so stacking them just doubles the melatonin.
- Give it with food, every day. Consistency does more than any single dose.
- Time it for the trigger. 30 to 60 minutes before the car, the groomer or dusk on a fireworks night, not once the shaking has started. The fireworks prep plan lays out the week.
- Keep simple notes. How long the evening pacing lasts, how fast your dog settles after the doorbell. A few weeks of notes tell you more than a gut feeling.
- Check with your vet first if your dog is on medication, pregnant or diabetic, and see the vet, not the supplement aisle, for panic, self-injury or anxiety that appears suddenly.
Help her wind down at dusk and still be herself
If the hard part of your dog's day is the evening, the formula should be built for the evening. OcuLabs Calming + Anxiety Support Chews put a printed melatonin dose next to the classic calming botanicals, in a chicken chew she will take from your hand.
- Settles at dusk without going flat. Valerian root 50 mg and melatonin 4 mg per two chews support relaxation and a settled evening rhythm.
- Calmer when the triggers come. Chamomile 80 mg and passion flower 30 mg support relaxation and calm behaviour.
- Steadier nerves day to day. Vitamin B1 30 mg supports normal nervous-system function, and L-theanine 3 mg is associated with calm focus.
- Still herself. Non-sedating, chicken-flavoured, with no corn, wheat, soy, artificial colours or added sugar.
Give two chews a day with or after a meal, or 30 to 60 minutes before fireworks, travel or grooming. A jar holds 90 chews, a 45-day supply. For adult dogs.
Your first purchase is covered for 90 days from delivery. If they are not right for your dog, email support@ocupetlabs.com for a full refund of the product price, opened or empty jars included.

Frequently asked questions
Which is better, Zesty Paws Calming Bites or OcuLabs Calming Chews?
For a dog who struggles in the evening, OcuLabs Calming Chews: every active has its own printed amount, including melatonin 4 mg and valerian root 50 mg per two chews, on a short chicken-flavoured list with no corn, wheat, soy, artificial colours or added sugar. Zesty Paws Advanced Calming Bites list valerian and melatonin inside a relaxation blend, with no separate figure for either.
Does Zesty Paws Calming Bites contain melatonin?
Yes, but you cannot see how much. In Zesty Paws Advanced Calming Bites, melatonin sits inside a relaxation blend with valerian and has no figure of its own. OcuLabs Calming Chews print it: 4 mg per two chews, inside the range vets commonly use.
Which is better for a dog that cannot settle at night?
OcuLabs. It prints melatonin at 4 mg per serving and pairs it with valerian root 50 mg, the evening wind-down combination, so you know what your dog is getting at dusk. For the 6pm pacing and 3am restlessness senior dogs get, that printed dose is the deciding detail.
Which is better for a dog with a sensitive stomach?
OcuLabs, for the short list: seven named actives, chicken-flavoured, with no corn, wheat, soy, artificial colours or added sugar. Fewer actives means less for a touchy gut to handle, and if something does not agree with your dog, a short list is easier to troubleshoot.
Can I give Zesty Paws and OcuLabs calming chews together?
There is no need, and OcuLabs is designed to be the whole daily routine on its own. The two overlap on chamomile, valerian, passion flower, hemp, L-theanine and melatonin, so giving both doubles up. Choose one, give it daily with food, and 30 to 60 minutes before predictable triggers.
