Who Is It Designed For?
If your dog scratches at night, licks or chews their paws, rubs their face on the carpet, nibbles at their belly, or has dry, flaky skin and a dull coat — and it comes back every spring and summer — this was made for your dog.
The itch shows on the skin, but it often starts in the gut. Most of your dog's immune system sits in the gut. When the gut is out of balance, everyday things like pollen, grass and dust can bother your dog more than they should, and you see it as scratching and licking.
Sprays, shampoos and wipes soothe the surface for a while. This works from the inside, every day: probiotics, prebiotics and postbiotics for a balanced gut, plus colostrum, omega 3-6-9 and vitamin E for healthy skin and a shiny coat, in one tasty soft chew.
Made for dogs of every size from 12 weeks old, dosed by weight.
The 6 Things This Formula Was Built For
Six ingredients, each with a job. Not a spray, not just another fish oil.
1. A balanced gut. A blend of three spore-forming probiotic strains (1 billion CFU per chew), fed by prebiotic fibres (FOS and GOS), helps maintain healthy gut flora.
2. A normal immune response. Bovine colostrum (350 mg per chew) and a postbiotic yeast blend support your dog's natural defences and a balanced immune response.
3. Less seasonal scratching. Supporting the gut and the skin together helps with occasional itching and scratching, especially when the seasons change.
4. Less paw licking. Calmer, more comfortable skin means less reason to lick and chew at paws, legs and belly.
5. Healthy, hydrated skin. Omega 3-6-9 from krill and borage oil (with GLA, EPA and DHA) and vitamin E help maintain the skin's moisture and its natural barrier.
6. A soft, shiny coat. The same fatty acids and vitamin E support a glossy coat and help reduce the dry, flaky look.
How It Works
Scratching, paw licking and face rubbing are your dog's way of telling you their skin is uncomfortable. Very often it's seasonal: pollen, grass and dust are everywhere in spring and summer. But how strongly your dog reacts depends a lot on what's happening in the gut.
What's actually happening:
Most of the immune system lives in the gut lining → when gut bacteria are out of balance, the immune response can overreact.
That overreaction shows up on the skin → scratching, licking, dry flaky patches.
Scratching and licking dry the skin out further → the coat looks dull and the cycle goes on.
Why what you've tried hasn't lasted:
Sprays, shampoos and wipes soothe the surface until the next walk or bath.
Plain fish oil does one job, omega-3, and nothing for the gut.
Cones and socks stop the licking, not the reason for it.
How Syntro Allergy & Skin works differently. It supports the skin from the gut out:
✓ Pre-, pro- and postbiotics — 1 billion CFU of spore-forming probiotics, FOS and GOS fibres and a postbiotic yeast blend for a balanced gut.
✓ Bovine colostrum, 350 mg — supports a normal, balanced immune response.
✓ Omega 3-6-9 from krill and borage oil — with GLA, EPA and DHA for hydrated skin.
✓ Vitamin E — an antioxidant for skin and coat health.
One to three soft chews a day, depending on your dog's weight. Dogs eat them like a treat.
What to Expect — Your First 90 Days
Here's what dog parents typically report. The gut takes a few weeks to rebalance, so give it two to four weeks of daily chews for the first changes — some dogs settle sooner.
Days 1–14 — the gut phase. The probiotics and prebiotics start supporting your dog's gut. Many owners first notice a more settled tummy and a dog that looks forward to the daily chew.
Weeks 2–4 — the settling phase. Scratching and paw licking start to ease, and nights get quieter.
Weeks 4–8 — the skin phase. Skin looks calmer, there's less dry flaking, and the coat starts to feel softer and look shinier.
Days 60–90 — the new-normal phase. Comfortable skin and a glossy coat become your dog's normal, right through the itchy season. This is when owners stop thinking of it as a supplement and start thinking of it as part of breakfast.
Pollen, grass and dust don't take a day off. That's why most dog parents keep going past the first jar.
How To Use
Give the soft chews once a day, by hand like a treat or crumbled over food, based on your dog's weight:
Under 25 lb (11 kg): 1 soft chew a day
25–75 lb (11–34 kg): 2 soft chews a day
Over 75 lb (34 kg): 3 soft chews a day
Each jar holds 60 soft chews: 30 days for a dog on 2 chews a day, 60 days for a small dog on 1. Fresh water should always be available. Consistency is what makes the difference: most dogs settle within 2–4 weeks, with skin and coat building over 4–12 weeks. Store in a cool, dry place and reseal the jar after use.
This is a complementary feed for dogs, not a medicine. Do not exceed the daily amount for your dog's weight. For dogs from 12 weeks old; not for cats. If your dog is pregnant, nursing, on medication or under treatment, ask your vet first. If the itching gets worse, or your dog has open sores, hair loss or ear problems, see your vet. Keep out of reach of children.

What dog parents report after 4 weeks on Syntro Allergy & Skin
What dog parents are actually saying
“We'd tried socks, wipes and a cone. Three weeks into these, Bella finally left her paws alone.”
Sarah M., 42 · Paw licking“Luna used to wake me up scratching. By week four the nights were quiet and her skin looked calm.”
Jessica R., 36 · Itchy skin“Rocky's coat was dull and flaky. Two months in, it had a shine I hadn't seen in years.”
David K., 58 · Dull, flaky coat
The Itch Shows on the Skin. It Starts in the Gut.
Scratching, Day and Night
Probiotics, prebiotics and colostrum support a balanced gut and a normal immune response, so everyday pollen, grass and dust bother your dog less, and the scratching, the thumping on the floor at night, eases off.
Paw Licking & Chewing
Calmer, more comfortable skin means less reason to lick and chew. Owners see fewer rusty-stained paws and quieter evenings on the sofa.
Dry, Flaky Skin & a Dull Coat
Omega 3-6-9 from krill and borage oil, plus vitamin E, help keep skin hydrated and support its natural barrier, for less flaking and a softer, shinier coat.
The Same Itchy Season Every Year
Started a few weeks before spring and given every day, the chews support your dog's skin right through the season, instead of chasing each itchy spell with a new spray.
Six Ingredients. One Tasty Daily Chew.
Probiotic Blend, 1 Billion CFU
Three spore-forming probiotic strains per chew, built to survive the stomach and support healthy gut flora, where most of the immune system lives.
Bovine Colostrum, 350 mg
The protein-rich first milk, packed with natural immune factors. It supports a normal immune response and a healthy gut lining.
Prebiotic Fibres (FOS + GOS)
200 mg of fibres that feed the good bacteria, so the probiotics have something to grow on and the gut stays in balance.
Postbiotic Yeast Blend
A three-strain yeast fermentate that supports gut balance and immune function, the finishing touch to the pre- and probiotics.
Omega 3-6-9: Krill & Borage Oil
Marine and plant omegas with GLA, EPA and DHA, to help keep the skin hydrated and the coat soft and glossy.
Vitamin E
An antioxidant that helps maintain skin moisture and supports healthy skin and coat. Completes the formula in a tasty pork-liver chew.
Your Dog's First 90 Days on Syntro Allergy & Skin
Bella was sitting by the cupboard waiting for her chew by day three. I didn't expect much that early, but she was calmer in the evenings.
Days 1–14
The gut phase
The probiotics, prebiotics and postbiotics start supporting your dog's gut from the first chew. Many owners first notice a more settled tummy and a dog who waits by the jar every morning.
- 🐾 Loves the daily chew
- 🌿 Gut support begins
- 😌 A settled tummy
Around week three I realised Luna hadn't woken me up scratching all week. That's when I knew it was doing something.
Weeks 2–4
The settling phase
As the gut finds its balance, scratching and paw licking start to ease, and nights get quieter. Colostrum and omega oils keep supporting the skin from inside.
- 🐾 Less paw licking
- 😴 Quieter nights
- 💧 More comfortable skin
Six weeks in, the spring scratching that used to keep us up just wasn't there. Max's coat looks great too.
Weeks 4–8
The skin phase
This is when it shows: calmer-looking skin, less dry flaking, and a coat that feels softer and looks shinier. Many owners say friends notice the coat before they do.
- ✨ Shinier coat
- 🌿 Calmer-looking skin
- 🐕 A comfortable dog
Month three. Daisy used to lick her paws every evening after our walk. Now she just curls up on the sofa.
Days 60–90
The new-normal phase
Pollen, grass and dust are out there every day, and so is the support. Kept up, it compounds — comfortable skin and a glossy coat become your dog's normal, right through the season. This is why most dog parents keep going past the first jar.
- 📈 Comfort that lasts
- 🌸 Through the whole season
- 🔁 A habit your dog loves
Not a Spray. Not Just Fish Oil.
Syntro Allergy & Skin
Sprays, Shampoos & Fish Oil
Made For One Job: A Comfortable Dog
Most owners blame the grass, the shampoo or just their dog's breed. Often the itch starts further in: a gut out of balance and skin that has dried out. Syntro Allergy & Skin isn't a spray and it isn't just another fish oil. It supports your dog's skin from the gut out, every day, in one tasty chew. Here's what dog parents report after 4 weeks.

See your vet if the itching is severe or getting worse, if your dog has open sores, hair loss or ear problems, or if your dog is pregnant, nursing or on medication.

Questions About Syntro Allergy & Skin
Why would a gut supplement help my dog's itching?
Because the skin and the gut are closely linked. Most of your dog's immune system sits in the gut lining, and the balance of bacteria there helps decide how strongly the body reacts to everyday things like pollen, grass and dust. When the gut is out of balance, that reaction can show up on the skin as scratching, licking and dry patches.
Syntro Allergy & Skin supports both sides at once: pre-, pro- and postbiotics and colostrum for the gut and a normal immune response, and omega 3-6-9 and vitamin E for the skin and coat.
My dog gets itchy every spring and summer. Is this for them?
Yes, that's exactly who it was made for: dogs whose scratching, paw licking and face rubbing come back with the seasons. For the best results, start the chews two to four weeks before the season begins and give them every day.
It's a complementary feed that supports skin, coat and a normal immune response; it isn't a medicine and doesn't replace your vet's care. If the itching is severe or getting worse, or your dog has open sores, hair loss or ear problems, see your vet.
Can I give it with my dog's medication or other supplements?
It can generally be given alongside a normal diet and most supplements, including fish oil. If your dog is on medication or under treatment for their skin or anything else, ask your vet before you start: some ingredients can slow the absorption of medicines taken at the same time. Never stop or change a treatment your vet prescribed.
Will my picky dog actually eat it?
Most dogs eat them straight from your hand: they're soft, pork-liver-flavoured chews. For a fussy eater, crumble the chew over their food, or give it as a reward after a walk. Natural colour variation between chews is normal.
Is this a medicine or an anti-itch treatment?
No. It's a daily complementary feed for dogs, a supplement in the form of a soft chew, that supports skin and coat health, gut balance and a normal immune response from the inside. Sprays and shampoos soothe the surface for a while; this supports your dog every day. It doesn't replace your vet's advice or treatment.
What's actually inside it?
Per soft chew: a blend of three spore-forming probiotic strains (1 billion CFU), bovine colostrum 350 mg, FOS 100 mg and GOS 100 mg (prebiotic fibres), a postbiotic yeast blend 75 mg, omega 3-6-9 fatty acids from krill and borage oil 68 mg (GLA 14 mg, EPA 6 mg, DHA 2 mg) and vitamin E 3.3 mg.
In a pork-liver soft chew with chickpea, sweet potato, coconut oil, coconut glycerin, sunflower oil, apple cider vinegar, lecithin, maltodextrin, rosemary extract and a natural smoke flavour. 60 soft chews per jar. Third-party tested.
Is it safe for my dog? What about puppies?
It's made for dogs of every size from 12 weeks old. Follow the daily amount for your dog's weight (1 chew under 11 kg, 2 chews from 11 to 34 kg, 3 chews over 34 kg) and don't give more. Ask your vet first if your dog is pregnant, nursing, intended for breeding, on medication or under treatment. It's made for dogs only: please don't give it to cats. If your dog eats too many by accident, call your vet. Keep the jar out of reach of children and pets.
I've already tried other things. Why would this be different?
Because most of what you've tried works on the surface, or does only one job. Sprays, shampoos and wipes soothe the skin until the next walk or bath. Plain fish oil gives omega-3 but does nothing for the gut. Cones and socks stop the licking, not the reason for it. Syntro Allergy & Skin supports the skin from the gut out — pre-, pro- and postbiotics, colostrum, omega 3-6-9 and vitamin E in one daily chew — and you have 90 days to see the difference.
How quickly will I notice a difference?
Many owners notice less scratching and paw licking within 2–4 weeks. Calmer-looking skin and a softer, shinier coat usually build over 4–8 weeks, because skin and coat renew slowly. Full results build over 60–90 days of daily chews — and you have 90 full days to decide, risk-free.
How do I give it?
Once a day, by hand like a treat or crumbled over food:
Under 25 lb (11 kg): 1 soft chew a day
25–75 lb (11–34 kg): 2 soft chews a day
Over 75 lb (34 kg): 3 soft chews a day
Each jar holds 60 soft chews, a 30-day supply for a dog on 2 chews a day. Keep fresh water available. Store somewhere cool and dry, and reseal the jar after use.
Does my dog need to keep taking it?
Pollen, grass and dust don't take a break, especially in spring and summer. Most dog parents keep giving the chews to hold on to the results; stop, and the support tends to fade over the following weeks. That's why the 3-jar option is the most popular.
How fast is delivery?
