She is fine in the morning. Then the light goes, and the pacing starts: kitchen, hallway, your side of the bed, back again. If that is the pattern, the chew you want is the one built for evenings and sleep.
Quick answer: OcuLabs Calming + Anxiety Support Chews are built to settle a dog and support sleep: chamomile 80 mg, valerian root 50 mg, passion flower 30 mg and a printed 4 mg of melatonin per two chews. PetLab Co Calming Chews contain no chamomile, valerian or melatonin. For evening pacing, night waking, storms and travel, OcuLabs is the one built for it, and a jar lasts 45 days against a 30-day bag.
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 with no corn, wheat, soy, artificial colours or added sugar.

Why OcuLabs suits the dog who struggles at night
It is built for settling and sleep. OcuLabs Calming Chews are the traditional calming botanicals with every amount printed, plus a melatonin dose you can read. That matters for the senior who paces from 6pm, whines at bedtime and wakes at 3am. Two chews with dinner, or 30 to 60 minutes before fireworks, the groomer or the car.
Your dog stays themselves. The formula is non-sedating, chicken-flavoured and free of corn, wheat, soy, artificial colours and added sugar. The hemp in it is hemp seed oil, an omega-rich seed oil with no CBD; CBD vs hemp seed oil for dogs explains the difference.
Gut support gets its own product. OcuLabs keeps it in Turkey Tail+, a mushroom powder with 1 billion CFU of Bacillus subtilis for dogs aged 7 and up, so the calming chew stays focused on calm. A senior with both problems can have both, each at its own full formula. For how CFU counts work, read probiotics for dogs.

Choose OcuLabs Calming Chews if
- The trouble peaks in the evening: pacing, bedtime whining, night waking.
- You have predictable triggers ahead, such as fireworks, travel or grooming.
- You want chamomile, valerian and a printed melatonin dose.
- You want a pack that lasts 45 days and a 90-day window to judge it.
Nerves, gut or both? Notice it this week
Before you buy anything, spend a week noticing when the stress shows.
- Note the time. Pacing that starts at dusk and broken nights point to an evening problem, which is what OcuLabs Calming Chews are built for.
- Note the trigger. Fireworks, the car and the groomer are predictable, so a serving timed 30 to 60 minutes before can do its work.
- Note the stomach. Loose stools, gas or skipped meals around triggers mean the gut is part of the picture. For a senior, add Turkey Tail+ alongside the calming chew.
- See your vet if loose stools keep coming back or come with vomiting, blood or weight loss, or if night pacing is new in an older dog. Those are medical before they are behavioural.
Help her settle in the evening and sleep through
If her stress shows up after dark, the formula should be built for after dark. 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.
- Easier evenings. 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, so she still eats, plays and comes to greet you.
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
Does PetLab Co Calming Chews contain melatonin?
No. OcuLabs Calming Chews do, at a printed 4 mg per two chews, next to chamomile 80 mg and valerian root 50 mg. PetLab Co Calming Chews contain no melatonin, chamomile or valerian.
Which is better for storms and fireworks?
OcuLabs, given daily through the season, with that day's two chews timed 30 to 60 minutes before dark or the forecast storm. It carries chamomile, valerian and melatonin, which PetLab Co's chew does not. If your dog panics, hurts themselves or tries to escape, see your vet about prescription options.
How long does a jar of OcuLabs or a bag of PetLab Co last?
An OcuLabs jar lasts 45 days: 90 chews at two a day. A PetLab Co bag lasts 30 days: 30 chews at one a day. Compare the price per day of supply on the day you buy.
Which is better for a senior dog restless at night?
OcuLabs, for the printed 4 mg of melatonin with valerian and chamomile, which PetLab Co's formula does not contain. If the restlessness is new, ask your vet to check for pain or cognitive changes first.
Which is better for a dog with a nervous stomach?
For a senior dog, OcuLabs splits the job across two products so each gets its own full formula: Calming Chews for the nerves, and Turkey Tail+, with 1 billion CFU of Bacillus subtilis, for gut support. If loose stools keep coming back, or come with vomiting or weight loss, see your vet.
