Breath Buddy is a bacon-flavored daily dental powder from Fifth & Fido for dogs and cats. It helps keep teeth clean and supports fresh breath as part of a daily oral care routine. One tub is 30 servings at $31.99, or $23.99 on the 30-day subscribe-and-save, backed by a 90-day money-back guarantee.
Updated 2 September 2026. Fifth & Fido now publishes per-scoop ingredient amounts on the product page, and the formula includes two ingredients an earlier version of this article missed. The full corrected list is below.
What is actually in Breath Buddy?
Seven ingredients, split between two jobs: the dental and fresh-breath side, and the gut-tolerance side.
| Ingredient | Per scoop | What Fifth & Fido says it is there for |
|---|---|---|
| Brown algae | 1,000 mg | Supports healthy teeth and gums |
| Zeolite | 400 mg | Daily dental care |
| Pomegranate powder | 300 mg | Supports the proper balance of normal oral flora |
| L-glutamine | 200 mg | Supports normal intestinal health |
| Turkey tail mushroom | 100 mg | Gut and normal immune system support |
| Cranberry powder | 100 mg | Targets breath odor |
| Marshmallow root | Amount not published | Supports normal digestive function |
If a specific amount matters for your pet and it is not listed above, ask Fifth & Fido support before buying rather than assuming.
Why is there turkey tail mushroom in a dental product?
It is not there for the teeth. Turkey tail sits on the gut-support side of the formula alongside L-glutamine and marshmallow root. That trio is how Fifth & Fido keeps a daily powder tolerable for pets with sensitive stomachs without leaning on a probiotic blend. The dental work is done by brown algae, zeolite, pomegranate and cranberry.
Does Breath Buddy contain probiotics?
No, and that is deliberate. Most dental powders lead with a large probiotic CFU count, and introducing that at full dose is one of the most common reasons owners quit in week one with loose stool. Fifth & Fido calls its approach a Gentle Formula: no probiotic megadose, with gut support coming from L-glutamine, turkey tail mushroom and marshmallow root instead.
If you specifically want a probiotic in the mix, that is a different product — Turkey Tail+ includes Lactobacillus acidophilus. And if your pet has a genuinely reactive stomach, our sensitive-stomach dental guide covers how to read a label for tolerance.
Is it for cats as well as dogs?
Both. That matters in a mixed household, since most dental products are dog-only. The bacon flavor is designed to mix into wet food, which is how most cats will take anything at all. One tub is 30 servings, so sharing it across two pets runs it out roughly twice as fast — and mix each pet's serving into their own bowl so you know who actually got it.
How do you give it?
One scoop over wet food, or mixed with broth or water, once a day. If your pet has a sensitive stomach, easing in with a smaller amount over the first week is sensible before moving to the full scoop. One tub is 30 servings — about a month, or roughly $1.07 a day at the one-time price, and about $0.80 a day on subscription.
So does it work?
The honest answer: individual pets vary, and Fifth & Fido does not promise a specific result on a specific day. Across 14 customer reviews the product averages 4.57 out of 5. Some owners report a noticeable difference within the first couple of weeks; others do not. That range is normal for any daily supplement.
What is worth being precise about is the mechanism people expect versus what a supplement can do. Plaque begins hardening into tartar within roughly 24 to 72 hours. Daily home care is aimed at that window. Once tartar has hardened along and below the gum line, it comes off only with veterinary instruments, under anesthesia. No powder changes that, and any product implying otherwise is telling you something it cannot deliver.
What Breath Buddy will not do
- It will not remove hardened tartar.
- It will not replace a professional dental cleaning or a veterinary exam.
- It will not substitute for brushing, which is still the most effective home method — it is what you use when brushing is not happening.
- It is not a treatment for any condition. Sudden breath changes, pawing at the face, dropping food or bleeding gums are veterinary signals, not shopping decisions. See the five signs worth acting on.
One caution worth reading
Brown algae is a seaweed, and seaweed-derived ingredients are naturally rich in iodine with levels that vary widely by source. Fifth & Fido does not publish an iodine amount for Breath Buddy, so check with your veterinarian first if your pet has a thyroid condition or takes thyroid medication.
How does it compare to the alternatives?
Against dental chews: the powder adds negligible calories and no tooth-fracture risk, but no mechanical scrubbing. Against water additives: a topper gives you a measured daily dose rather than one that depends on how much your pet drank. Against high-CFU dental powders: gentler at introduction, at the cost of no probiotic.
The full breakdown is in our guide to dental powder vs chews vs water additives, and the buying criteria are in our 2026 buyer's guide for pets that won't be brushed. If you have a small or flat-faced breed, format matters more than usual — see the guide for Frenchies, pugs, Yorkies and Shih Tzus.
