Most dog owners take a dental product’s promises on faith. There is rarely a way to see, in real terms, whether it is actually working.
Dental chews and supplements routinely claim to support oral health, and most contain ingredients with some research behind them. What is harder to find is a side-by-side look at how a specific product performs against a specific competitor, measured the same way, on the same timeline.
That gap is what pushed Dr. Steve Mehler, veterinary specialist and co-founder of Prodogi, to run a controlled study rather than rely on ingredient claims alone.
“We wanted data we could stand behind, not just a formula we believed in,” Dr. Mehler says.
Over 14 days, researchers followed 20 dogs split between Prodogi’s dental strips and a leading dental supplement, measuring oral bacteria and breath markers at the start and end of the study under standardized conditions.
The results were measurable across every metric tracked. Dogs using Prodogi’s strips saw an average 80 percent reduction in bad breath within the 14-day window, a 41 percent greater breath improvement than the comparison group, and a 25 percent greater reduction in plaque-causing bacteria.
The strips also performed three times better than the leading supplement on hard-to-reach teeth, and twice as many dogs showed a significant bacterial reduction overall.
The study tracked three layers of data. The primary measure was halitosis, scored through a standardized breath assessment. A secondary measure tracked overall bacterial load, and a tertiary measure isolated bacterial reduction specifically on hard-to-reach teeth, the surfaces owners rarely see and brushing alone struggles to reach.
To visualize the change, veterinarians used a calibrated blue-light fluorescence device to map bacterial plaque across each dog’s teeth at Day 0 and again at Day 14. Under that light, plaque-causing bacteria fluoresce red. Clean surfaces appear white or pale green.
The before-and-after images showed a clear shift from red to white and green across the study group, a visible record of the same reduction the lab metrics captured.
Dr. Mehler points to delivery format as the reason for the gap between strips and other formats.
“A strip dissolves across the full oral cavity,” he says. “That reaches surfaces a chew or a swallowed supplement routinely misses.”
That extended contact time between the strip’s active ingredients and the tooth surface, particularly at the back of the mouth where plaque tends to build up unnoticed, is what the study’s data traces back to.
A chew works for the seconds a dog spends crunching it. A strip stays in contact with the gumline and back teeth for longer, which the study’s hard-to-reach surface data appears to bear out.
Dr. Mehler is careful to draw a line between what the study shows and what it does not.
“We distinguish between controlled comparative findings at the product level and published research at the ingredient level,” he says. “Neither gets presented as the other.”
That distinction matters in a category where ingredient studies are often stretched to imply results for a finished product they were never tested in. Prodogi’s data was measured using its actual strip, on real dogs, against a real competitor, not extrapolated from a lab study of a single compound.
It is a distinction that matters to pet owners scanning ingredient lists for familiar names. A compound shown to help in a petri dish or a single feeding trial is not the same as that compound performing inside a finished product, used the way a dog owner would actually use it, measured against a real competitor on the shelf.
For Dr. Mehler, the results reinforce what drove the product’s original formulation.
“This has always come down to supporting healthy teeth and gums without asking pet owners to take that on faith,” he says. “Now there’s a study behind it.”
Periodontal disease in dogs often goes unnoticed until a veterinarian flags it at a checkup, by which point inflammation has typically been building for some time. Products that support periodontal function and gum tissue health, used consistently, give owners a way to stay ahead of that timeline rather than react to it.
Left unaddressed, the bacteria behind periodontal disease do not stay contained to the mouth. Veterinary research has linked chronic oral inflammation to added strain on the heart, kidneys and other organ systems over time, which is part of why consistent oral care carries weight beyond fresher breath.
That is the case Dr. Mehler makes to owners who assume a dental product is a cosmetic extra rather than a baseline health habit.
