BPA in Canned Dog Food Causes Changes in Microbiota
“Bisphenol A is a prevalent endocrine-disrupting chemical found in canned foods and beverages,” said Cheryl Rosenfeld, an associate professor of biomedical sciences in the MU College of Veterinary Medicine and an investigator in the Bond Life Sciences Center. “We wanted to determine if short-term feeding of widely available commercial canned food could alter BPA concentrations in dogs. Thus, we assessed BPA contained within pet food cans. We also analyzed whether disturbances in bacteria found in the gut and metabolic changes could be associated with exposure to BPA from the canned food.”

“The dogs in the study did have minimal circulating BPA in their blood when it was drawn for the baseline,” Rosenfeld said. “However, BPA increased nearly three-fold after being on the either of the two canned diets for two weeks. We also found that increased serum BPA concentrations were correlated with gut microbiome and metabolic changes in the dogs analyzed. Increased BPA may also reduce one bacterium that has the ability to metabolize BPA and related environmental chemicals.”
Dogs who share internal and external environments with their owners are likely excellent indicators of the effects of BPA and other industrial chemicals on human health.
“We share our homes with our dogs,” Rosenfeld said. “Thus, these findings could have implications and relevance to humans. Indeed, our canine companions may be the best bio-sentinels for human health concerns.”

That’s why you make your own, duh.
Dogs are just other living beings, and kibble doesn’t grow on trees or fall out of rabbits, so why would that be all you feed man’s best friend?
Some foods are bad for dogs, some fruits and vegetables they shouldn’t have, but a ton of stuff you eat, is great for dogs too.
I may use a little made in America dry kibble, with easy to pronounce ingredients, but mainly I add chopped fruits, veggies, cheese, grains, and fresh meats. Generally we use whatever were making for dinner for ourselves, minus anything dogs can’t eat.
There’s good brands of canned dog food, and dogs generally love it, but I rarely buy it for my pooch.
