Research & Formulation
The Science Behind Our Formulations
Evidence-led ingredients, considered combinations, and a clear purpose behind every formula.
Verification & standards
How Oscar is made,
and how it is checked.
Oscar is independently tested, while manufacturing is carried out by facilities operating under applicable quality and food-safety standards.
Independent Testing Laboratory
A Small Gain in Digestibility
In 10 Beagles, B. coagulans GBI-30, 6086 at about 1.3 billion CFU a day raised energy and organic-matter digestibility by roughly 2 percentage points. A second measuring method found no change, and stools were unaffected. Supplier-funded.
Digestibility
No Protection During a Diet Switch
When 12 dogs were switched abruptly from dry to canned food, B. coagulans GBI-30, 6086 did not prevent the looser stools and gut-bacteria shifts that followed. The lower dose raised Faecalibacterium, a butyrate-producing gut bacterium. Supplier-funded.
Slightly Firmer Stools
In 12 healthy dogs, B. coagulans GBI-30, 6086 lowered the average stool score from 3.2 to about 2.8 on a 5-point scale, where lower is firmer. Neither dose differed from placebo on its own, and digestibility did not change. Supplier-funded.
Better Protein and Fibre Digestion
In 18 healthy Golden Retrievers, 30 days of B. subtilis C-3102 at either of two levels improved digestibility of dry matter, protein and fibre and raised faecal lactobacilli. The higher level also gave firmer stools and less faecal ammonia.
Digestibility
Firmer Stools, Less Ammonia
In 12 young Beagles, a diet with B. subtilis C-3102 gave firmer, drier stools (39.1% vs 36.5% dry matter) and less faecal ammonia, a protein-breakdown by-product, than the same diet without it. Digestibility did not change.
Lower Gut-Inflammation Marker in a Blend
In 24 Beagles, 31 days on a chew combining B. clausii, B. subtilis and B. coagulans with FOS, GOS and yeast extract lowered faecal calprotectin and raised microbial diversity versus a control chew. B. clausii was not tested alone; the chew's maker funded the study.
More Bifidobacteria and Butyrate
Healthy adult dogs given 2 g of FOS twice a day had more faecal bifidobacteria and butyrate, and less ammonia and other protein-fermentation by-products, than dogs given a control. Lactobacilli only trended upward.
Better Mineral Uptake, More Ammonia
In 12 healthy dogs, FOS at 1.5 g per kg of food raised the apparent digestibility of dry matter and of minerals including calcium, magnesium, zinc and iron. It also raised faecal ammonia, so the fermentation picture was mixed.
Stools Unchanged, Immune Cells More Active
In 24 healthy dogs, a diet with 1% GOS did not change digestibility, stool quality or most faecal fermentation products. It did increase the number and activity of certain white blood cells in laboratory tests.
More Butyrate and Bifidobacteria
In 20 healthy dogs, food with 1% GOS raised faecal acetate and butyrate, fatty acids made by gut bacteria, and increased bifidobacteria and lactobacilli. Enterobacteriaceae also rose, and overall bacterial diversity fell slightly.
More Short-Chain Fatty Acids in a Gut Model
In a laboratory model of the canine gut, a yeast cell wall product rich in beta-glucans and mannan-oligosaccharides increased propionate, acetate and butyrate and shifted several bacterial groups. It has not been confirmed in living dogs.
Fewer E. coli, Stools Unchanged
In five adult dogs, yeast cell wall at up to 0.65% of the diet lowered faecal E. coli as the amount rose. Bifidobacteria, lactobacilli and stool quality did not change, and effects on digestibility were inconsistent.
