Lauren J.
Bella started making this dry goose-honk cough at night and I genuinely thought I was going to lose her. Vet told us to start these and mix 3 drops in her food. Three nights on the drops and the coughing was already less — it's been getting quieter every day since.

I absolutely love this. Being a senior citizen myself I was always worried about my dogs health (over my own health) and their heart health too! but these drops have helped my chihuahua a lot. MooMoo loves the flavor of this and she can't wait to have it mixed with her food!

The vet recommended me this about 1 month ago because of my dog was honking like a goose. Fast forward 30 days, i came back here to write a review because he has STOPPED honking at night (all night long, i couldnt sleep before)

My dogs love these, because they come running after me as soon as they hear me open the cabinet where this is stored. This has helped my chihuahua's cough and we both can finally sleep better at night

By the time your dog coughs, his heart has already been struggling for months.
Dogs don't show heart trouble early. The muscle weakens quietly, the chambers stretch, and the heart grows until it starts pressing up against the windpipe — and that pressure is the cough. The honking, the gagging, the fits at 2am. It's the first thing you can hear, and it's the last thing to happen.
Even "premium" and "vet recommended" grain-free diets quietly leave the taurine gap open — and every day that gap goes unfilled, the heart muscle thins a little more.
PetCalm Co Advanced Taurine closes that gap — 99.9% pure taurine, precision-dosed by bodyweight, mixed straight into food. The one amino acid an ageing dog's heart runs on and their bowl stops supplying.
This means more quiet nights and more good years with your dog.
Don't wait until you can hear it. The strain may already be there, and you won't find out until it's pressing on his airway.
What Our Customers Are saying...
Trustpilot Reviews
Love this for my senior dog
It is helping — cough is noticeably less at about week five. But I'll be honest, I was expecting faster based on some of the reviews here, and I nearly quit at day 10 when nothing had changed. Stick with it. Just don't expect week one miracles.
Huge Difference!
Our vet suggested taurine while we waited on a cardiology referral. Wanted pure taurine, not a multivitamin with 30 things in it, and this was one of the few that was actually just taurine. Mixed into wet food, she has no clue it's there. Coughing eased off around the two week mark and her follow-up went well.
Worth Every Penny
Spent nearly a month treating what I thought was a throat thing. Vet took one listen and said his heart was enlarged and pressing on his airway — that's what the honking was. Changed his food and started this at the same time. Four weeks in and the night coughing has almost stopped
Finally Relief
Two dogs, both on the same boutique grain-free for years, one started coughing. Put both on this while we sorted the food out. The coughing one is much better and I feel a lot less like I'm waiting for the other shoe to drop with his brother.
Daily Health Nutrients, Made Simple.
Thousands of dog owners trust PetCalm Co.
Just a few drops of PetCalm Co Advanced Taurine mixed straight into food once a day, is enough to close the gap their bowl leaves open.
Taurine is the active ingredient — the amino acid the heart muscle uses to contract, and the one legume-heavy and grain-free diets quietly leave short. It keeps the heart wall strong instead of thin and stretched, and keeps the retina working as their eyes age.
Around it sits a full vitamin and mineral complex — the B-group they burn through daily and can't store, plus the antioxidant vitamins that ageing bodies stop using efficiently. Together that's the heart supported, the eyes protected, and the everyday energy back for the walk, the stairs, the toy they used to bring you.
No fillers, no gums, no pill battle. Precision-dosed by bodyweight, straight into their dinner — they won't know it's there.

Frequently Asked Questions
How fast will I see a difference?
+
Most owners notice a change in the first 2–4 weeks. Some see the night coughing ease sooner. We'd rather tell you the truth than promise 48 hours — this is rebuilding what's been missing, and that takes a little time. Give it a full month before you judge it.
My food already says it has added taurine. Why do I need this?
+
Because added taurine and absorbed taurine aren't the same thing.
Dog food is processed at a very high heat which KILLS 98% of Taurine, leaving your dog with nothing at all
Legume-heavy and grain-free formulas can interfere with how taurine is processed — which is exactly why dogs on "premium" food still turn up short. Pure, unbound taurine bypasses that problem.
Will my picky dog actually eat it?
+
They'll think it's a treat. Advanced Taurine is a liquid drop in chicken liver flavour — the one flavour fussy dogs go for — so it doesn't get sniffed at and walked away from.
Straight into wet or dry food, prescription ANYTHING!. Mixes in instantly. Most dogs clean the bowl.
No prying his mouth open. No hiding pills in cheese. No finding it spat out on the carpet an hour later.
Why liquid instead of a powder or a tablet?
+
Because liquid is more potent and research shows its tolerated and absorbed better.
Powders clump, irritate your dogs mouth and esophagus— and you never really know how much went in. Tablets get spat out, wrapped in peanut butter, or turn into a daily wrestling match your dog starts hiding from.
Drops are measured to your dog's bodyweight, mix in clean, and taste like something he wants. No scoop, no mess, no colour change in the bottle. Two seconds and it's done.
Can I give it with his heart medication?
+
Yes — but check with your vet first. Taurine is commonly used alongside cardiac medication rather than instead of it. Never stop a prescribed medication to use a supplement.
Is this third-party tested?
+
Yes. Every batch is tested by independent labs for purity, potency, and contaminants. Lab reports available upon request.
My dog isn't sick. Is this worth it?
+
This is the best time to start. Heart muscle thins quietly, long before there's anything to hear. By the time you can hear the cough, it's been happening for months. If he's on a grain-free or legume-heavy diet, or he's heading into his senior years, this is the window you actually want to be in.
My food already says it has added taurine. Why do I need this?
+
Because added taurine and absorbed taurine aren't the same thing.
