What is Smilers?
What is Smilers?
Smilers is a daily soft chew that tackles your dog's bad breath at the source. Most dental products only treat the surface, which is why the smell keeps coming back. Smilers uses oral and gut probiotics to rebalance the bacteria behind the odor, so your dog's mouth gets healthier from the inside out.
And since oral health affects the whole body, fixing the root cause supports your dog's overall wellbeing too. Best of all, it's vet-grade oral care in the chicken liver flavor dogs love, so they think it's a treat, not medicine.
Science & Certifications
Science & Certifications
Studied ingredients. Smilers is built around ingredients with published research behind them. Ascophyllum nodosum (brown seaweed extract) has been studied for its support of clean teeth in dogs over 8-12 weeks of daily use. Zinc methionine is one of the best-studied compounds for breath neutralization. Each ingredient earns its place. No fillers and no marketing-only actives.
Made in a cGMP-certified facility. Our chews are manufactured in a facility that follows current Good Manufacturing Practice standards. The same standards used for human supplements.
Third-party tested. Every batch is independently tested for active ingredient levels, microbial safety, and contaminants like heavy metals. We don't release a batch we wouldn't give our own dogs.
Xylitol-free, artificial-flavor-free. No xylitol, no artificial flavors, no artificial colors. Just chicken liver flavor - the tried and tested dog-favorite.

Frequently Asked Questions
Please contact our Customer Support Team at hello@smilersfordogs.com
You'll typically notice fresher breath within 7–14 days, as the fast-acting ingredients (zinc, parsley, green tea) get to work immediately. The deeper benefits, organ protection and cleaner teeth, build over the following weeks of daily use.
Most dental products work on the surface, scrubbing teeth, masking the smell, or relying on your dog to gnaw on something. Smilers works at the source: the bacteria in the mouth and gut that cause bad breath in the first place. It's also a tasty soft chew dogs actually want, with the exact dose every time, instead of a powder dogs pick around or a stick they might not chew.
Smilers works at the source of bad breath: the bacteria in your dog's mouth and gut. Most dental products clean the surface of the teeth. Smilers rebalances the bacteria that cause the smell in the first place. It combines fast-acting breath ingredients (zinc, parsley, green tea) for results you'll notice in days, with oral and gut probiotics and studied seaweed extract for long-term oral health.

Dosing is based on your dog's weight: 1 chew daily for small dogs (up to 22 lbs), 2 chews for medium dogs (22-55 lbs), and 3 chews for large dogs (55 lbs+). Full guide is on the back of every bag.
Smilers is made for healthy dogs, over 8 months of all sizes and breeds, in a cGMP-certified facility, third-party tested for quality and safety, and free from xylitol and artificial flavors. As with any supplement, check with your vet before starting if your dog is pregnant, nursing, on medication, or has a known health condition.
Both work. Unlike most dental chews that only work if your dog actually gnaws on them, Smilers works systemically. The probiotics, seaweed, and active ingredients do their job whether your dog savours every bite or inhales the whole chew in one go.
"Most owners underestimate how much oral health affects a dog’s overall wellbeing. Smilers makes daily dental care simple, which is why I recommend it as part of an at-home routine."
