Who Is It Designed For?
If your dog scratches, licks their paws or chews at their skin, if their coat looks dull or they shed more than they should, if their tummy is easily upset, or if they're slower on walks than they used to be — this was made for them.
Most of these signs don't start on the skin. They start in the bowl. Even good kibble is cooked at high heat, which is hard on the fragile omega-3s, friendly bacteria and vitamins a dog needs every day. The gaps show up first in the skin and coat, then in the gut, the joints and their energy.
Shampoos and sprays work on the surface for a day or two. This works from the inside, every day: salmon oil, probiotics, glucosamine, chondroitin and seven vitamins in one soft chew that dogs take like a treat.
Made for dogs of every breed and size from 3 months old — puppies, adults and seniors.
The 6 Things This Formula Was Built For
Twelve active ingredients, one soft chew — each one there for a reason. Not a shampoo. Not a one-job pill.
1. Calmer, less itchy skin. Omega-3s from wild Alaskan salmon oil and natural vitamin E help support healthy, comfortable skin, so there's less scratching and paw licking.
2. A soft, shiny coat. EPA, DHA and vitamin A nourish the skin and coat from the inside, for a glossier coat and less dry, flaky shedding.
3. Healthy digestion. 500 million CFU of probiotics plus a postbiotic support a balanced gut microbiome and firm, regular stools.
4. Everyday immune support. Much of your dog's immune system sits in the gut. Probiotics, vitamin A and vitamin E help support their natural defences.
5. Comfortable, mobile joints. 200 mg of glucosamine and 75 mg of chondroitin per chew help maintain healthy cartilage and easy movement, at every age.
6. Heart, energy and strong bones. B vitamins (B2, B6, folic acid and B12) and vitamin D3 support energy metabolism, normal heart function and healthy bones.
How It Works
Dogs need a steady supply of omega-3s, friendly bacteria and vitamins every day. Most eat the same processed food every day, cooked at high heat, and heat is hard on exactly these nutrients. When the supply runs short, the first place it shows is the largest organ your dog has: the skin.
What's actually happening:
Too few omega-3s → the skin barrier dries out → itching, flaking and a dull coat.
An unbalanced gut → soft stools, gas, and a gut that's less able to support the immune system.
Everyday wear on cartilage → stiffness after naps and slower walks, especially as dogs get older.
Why what you've tried hasn't fixed it:
Medicated shampoos and sprays soothe the surface for a day or two.
Fish oil pumps are messy, and many dogs refuse the taste.
Single supplements — one for skin, one for joints, one for the gut — add up fast, in cost and in effort.
Many chews are mostly fillers, palm oil and artificial flavours.
How Syntro Multivitamin works differently. One soft chew covers five daily needs at once:
✓ Wild Alaskan salmon oil — EPA and DHA omega-3s for skin and coat.
✓ 500 million CFU probiotics + a postbiotic — for a balanced gut and immune support.
✓ Glucosamine 200 mg + chondroitin 75 mg — for joints and mobility.
✓ Vitamins A, D3, E, B2, B6, B9 and B12 — for everyday health, energy and heart.
✓ Real chicken liver flavour — no artificial flavours, no palm oil, third-party tested.
One to three chews a day, by weight. That's it.
What to Expect — Your First 90 Days
Here's what dog parents typically report. Nutrients build up gradually, so give it three to six weeks of daily chews for the first changes — some dogs show them sooner.
Days 1–14 — the settling-in phase. The probiotics get to work in the gut. Many owners first notice firmer, more regular stools and a dog who waits by the jar every morning.
Weeks 2–4 — the skin phase. Omega-3s build up in the skin. Scratching and paw licking start to ease, and the skin looks less dry and flaky.
Weeks 4–8 — the coat phase. New hair grows in softer and shinier, shedding settles, and many owners notice an easier stride on walks.
Days 60–90 — the new-normal phase. The support compounds: calmer skin, a glossy coat, a settled tummy and comfortable joints. This is when the chew stops being a supplement and becomes part of your dog's day.
Your dog needs these nutrients every day, so the best results come from daily use over months. That's why most dog parents keep going past the first jar.
How To Use
Give the chews once a day, in the morning with a meal or on their own as a treat. Serve by weight:
- Up to 25 lb (11 kg): 1 chew a day
- 25–75 lb (11–34 kg): 2 chews a day
- Over 75 lb (34 kg): 3 chews a day
Each jar holds 60 soft chews: 60 days for a small dog, 30 days for a medium dog on 2 chews a day, 20 days for a large dog. Suitable for dogs from 3 months old. For best results, give it every day for at least 3 months. Keep the jar closed, in a cool, dry place.
Syntro Multivitamin is a complementary feed for dogs, not a medicine. Do not exceed the daily amount for your dog's weight. Ask your vet first if your dog is pregnant, nursing, on medication or under veterinary treatment. Not for cats. Keep out of reach of children. Always leave fresh drinking water available.

Your Dog's First 90 Days on Syntro Multivitamin
Bella was waiting by the cupboard for her chew by day three. Her tummy settled before I even noticed the itching easing.
Days 1–14
The settling-in phase
The probiotics get to work from the first chew. Most owners first notice firmer, more regular stools — and a dog who waits by the jar every morning.
- 🐕 A settled tummy
- 🦴 Loves the chew
- 🌿 An easy routine
Around week four I realised I hadn't heard Luna scratching at night. That's when I knew it was working.
Weeks 2–4
The skin phase
As omega-3s build up in the skin, scratching and paw licking start to ease and the skin looks less dry and flaky.
- 🐾 Less paw licking
- ✨ Calmer skin
- 😴 Quieter nights
Six weeks in, Max was keeping up on our morning walk again instead of lagging behind.
Weeks 4–8
The coat phase
New hair grows in nourished: a softer, shinier coat, less shedding on the sofa and an easier stride on walks. Many owners say friends notice before they do.
- ✨ Shinier coat
- 🧹 Less shedding
- 🦮 Easier walks
Two months in, the groomer asked what we'd changed. The answer is one chew with breakfast.
Days 60–90
The new-normal phase
Your dog needs these nutrients every day, and the support compounds. Kept up, calm skin, a glossy coat, a settled tummy and comfortable joints become their normal. This is why most dog parents keep going past the first jar.

Syntro Multivitamin
Shampoos & Single Supplements
Made For Every Day: Your Dog's Daily Basics
Most dog parents blame the season, the breed or the shampoo. Often it's what's missing from the bowl: everyday kibble is low in the fragile omega-3s, friendly bacteria and vitamins that skin, gut and joints depend on. Syntro Multivitamin isn't a shampoo and it isn't a one-job pill. It's one tasty chew that covers the daily basics. Here's what dog parents report after 4 weeks.
Figures are owner-reported, drawn from post-purchase feedback and reviews — not a clinical trial. Individual results vary. Syntro Multivitamin is a complementary feed for dogs, not a veterinary medicine: it is not intended to diagnose, treat, cure or prevent any disease, and it does not replace a balanced diet or your vet's advice. See your vet if your dog's itching, skin, ear or digestive problems are severe or sudden, and before use if your dog is pregnant, nursing, on medication or under veterinary treatment.

Questions About Syntro Multivitamin
Why would a multivitamin help with itching?
Because a lot of everyday itching, licking and dull coats start with what's missing from the bowl, not with the skin itself. The skin is your dog's largest organ, and it needs a steady supply of omega-3 fatty acids, vitamin A and vitamin E to stay supple and comfortable. Heat-processed kibble is often low in exactly these.
Syntro Multivitamin brings them back every day — wild Alaskan salmon oil, vitamins A and E — plus probiotics for the gut, where much of the immune system lives. It supports healthy skin from the inside. It isn't a medicine: if the itching is severe or sudden, or comes with sores, hair loss or ear problems, see your vet.
My dog already eats a good food. Do they still need this?
A complete food covers what your dog needs at a minimum. It isn't designed to deliver live probiotics (cooking destroys them), generous amounts of omega-3s or joint nutrients such as glucosamine and chondroitin. That's the gap a daily multivitamin fills.
Syntro Multivitamin is a complementary feed: it goes alongside a balanced diet, never instead of it.
Is it suitable for puppies and senior dogs?
Yes. It's suitable for dogs of every breed and size from 3 months old. Puppies get everyday support for skin, coat and digestion; older dogs also benefit from the glucosamine and chondroitin for comfortable joints. Just follow the chews-by-weight table. If your dog is pregnant or nursing, ask your vet first.
Can my dog take this with medication or other supplements?
It can be given alongside most foods and common supplements. If your dog is on medication, under veterinary treatment or has a health condition, check with your vet first. Never stop or change a treatment your vet has prescribed. If your dog already takes a fish oil or a joint supplement, tell your vet so they can look at the total.
Is this a treat, a medicine or a supplement?
It's a complementary feed: a daily supplement in the form of a soft chew that dogs take like a treat. It isn't a medicine, a shampoo or a spray. It supports skin, coat, digestion, joints and immunity from the inside, every day.
What's actually inside it?
Per soft chew (3 g): glucosamine HCl 200 mg (from shellfish), chondroitin 75 mg, wild Alaskan salmon oil 95 mg (EPA and DHA), probiotics 500 million CFU (Lactobacillus acidophilus, Bacillus coagulans, Enterococcus faecium), a postbiotic (dried Pediococcus acidilactici fermentation product, 75 mg), vitamin A 1,000 IU, natural vitamin E 4 IU, vitamin B2 1 mg, vitamin B6 1 mg, folic acid 0.22 mg, vitamin B12 5 µg and vitamin D3 2 µg. Made with chicken liver, brewer's yeast, coconut oil, sunflower lecithin and rosemary extract. No artificial flavours, no palm oil. 60 soft chews per jar. Third-party tested.
Is it safe? Are there side effects?
The chews are made with ingredients dogs tolerate well. Some dogs have softer stools for a few days while their gut adjusts to the probiotics; starting with one chew a day for the first week helps. The chews contain chicken and shellfish (glucosamine), so don't give them to a dog that is allergic to either. Stick to the daily amount for your dog's weight. Ask your vet first if your dog is pregnant, nursing, on medication or under treatment. Not for cats.
I've already tried other things. Why would this be different?
Because most of what you've tried works on the surface, or does one job at a time. Medicated shampoos and sprays soothe the skin for a day or two. A fish oil pump is messy and many dogs refuse it. Separate tubs for skin, joints and the gut add up fast. Syntro Multivitamin puts salmon oil, probiotics, glucosamine, chondroitin and seven vitamins in one chew your dog takes like a treat — and it works from the inside, every day.
How quickly will I notice a difference?
Many owners notice firmer stools within the first two weeks, and less scratching and paw licking within three to six weeks. A softer, shinier coat takes longer because it shows as new hair grows in: usually six to eight weeks. Full results build over 60–90 days of daily chews — and you have 90 full days to decide, risk-free.
How many chews does my dog need?
One to three chews a day, by weight: up to 25 lb (11 kg), 1 chew; 25–75 lb (11–34 kg), 2 chews; over 75 lb (34 kg), 3 chews. Give them in the morning with a meal or on their own. A jar of 60 lasts a small dog 60 days, a medium dog 30 days and a large dog 20 days. Always leave fresh water available.
Does my dog need to keep taking it?
Your dog needs omega-3s, friendly bacteria and vitamins every day, so the support works best when it's daily. Most dog parents keep going to hold on to the results; stop, and the benefits tend to fade over the following weeks. That's why the 3-jar option is the most popular.
How fast is delivery?
Orders leave our warehouse within 1 business day and most arrive in 3 to 5 business days. Free shipping on every order, and you'll get tracking by email the moment it ships.
