What puppies eat, and what happens later
University of Helsinki. Puppies fed at least 20% real food had significantly fewer allergy and skin problems as adults. Puppies fed mostly dry food had more.
Same research group. Raw bones or cartilage about twice a week was linked to a 33.2% lower risk of chronic digestive disease later in life. An ultra processed, carbohydrate heavy puppy diet was a risk factor.
The gut and the skin
Dogs with atopic skin disease had less diverse gut bacteria than healthy dogs. Correcting the gut improved the skin.
Measurable damage to the intestinal lining in dogs with allergic skin disease.
Lower gut microbial diversity in allergic dogs compared with healthy ones.
Food allergies
Mueller, Olivry and Prélaud. Across confirmed cases: beef 34%, dairy 17%, chicken 15%, wheat 13%, lamb 5%.
Signs appeared by 12 months of age in up to 38% of affected dogs. Early itching is more likely to be food related.
French Bulldogs specifically
72.4% of French Bulldogs had at least one recorded disorder. Skin problems 17.9%, ear infections 14%, diarrhoea 7.5%. Higher risk than other dogs for 20 of 43 common conditions.
Every dog examined had at least one gut abnormality. The worse the digestive signs, the worse the damage.
Poncet et al. 97.3% had gut lesions, including dogs showing no digestive symptoms at all.
Why flat faced breeds are prone to reflux, hiatal hernia and oesophagitis.
A fair word about all of this ♥
Most of these are large observational studies, which means they show strong links rather than proof of cause. The French Bulldog gut studies looked at dogs already unwell enough to be examined, so they don't describe every Frenchie. I've been careful not to overstate any of it.
I'm not a vet, and nothing here replaces one. If your Frenchie is unwell, please see yours.
The research is the why. The book is the how: what to feed, how much, and how to judge any food for yourself.
