Obesity-related health problems are becoming one of the most serious issues for dogs and cats in many countries, including Japan. According to the Association for Pet Obesity Prevention (APOP) 2022 survey, veterinarians classified 61% of cats and 59% of dogs as overweight or obese.<\/p>\n\n\n\n
As a result, pet food manufacturers have been developing a wide range of weight-management products to address this growing problem. But did you know that probiotics are also attracting attention as a potential tool for managing obesity in dogs and cats?<\/p>\n\n\n\n
The importance of probiotics for gut health is already well recognized, but some researchers have also reported that probiotics may help with weight management in dogs.<\/p>\n\n\n\n
In this study, scientists investigated the effects of two probiotics\u2014Enterococcus faecium<\/em> IDCC 2102 and Bifidobacterium lactis<\/em> IDCC 4301\u2014on dogs fed a high-fat diet.<\/p>\n\n\n\n According to an article published in Veterinary Microbiology<\/em>, \u201cthese probiotics enhanced systemic energy utilization in response to excess caloric intake, prevented lipid accumulation, and restored stability in the fecal microbiota.\u201d The study also reported that they reduced systemic inflammation caused by a high-fat diet.<\/p>\n\n\n\n Probiotics, the beneficial bacteria that live in the gut, play an important role in maintaining digestive health in both humans and pets. However, this study conducted in South Korea focused specifically on their effects on metabolism.<\/p>\n\n\n\n Researchers from Seoul National University, Kyungpook National University, and Chungnam National University explored whether these two probiotics could help alleviate obesity-related issues in dogs consuming a high-fat diet.<\/p>\n\n\n\n The results showed that both E. faecium<\/em> IDCC 2102 and B. lactis<\/em> IDCC 4301 significantly reduced weight gain and lipid accumulation in dogs fed a high-calorie diet.<\/p>\n\n\n\n The study also took a closer look at the biological mechanisms behind these effects, revealing notable benefits related to systemic inflammation, lipid metabolism, and hormonal regulation.<\/p>\n\n\n\n Both IDCC 2102 and IDCC 4301 were found to positively affect the gut microbiota by promoting beneficial bacterial groups such as Lactobacillaceae, Ruminococcaceae, and S24-7.<\/p>\n\n\n\n As a result, levels of pro-inflammatory bacteria associated with a high-fat diet were reduced, helping to improve gut balance and suppress inflammatory microbes. When inflammation decreases, normal fat-cell function can recover, excess fat accumulation can be reduced, and this may help prevent or improve obesity.<\/p>\n\n\n\n The probiotics promoted pyruvate metabolism, supported glucose regulation, and increased ATP (adenosine triphosphate) production. In particular, B. lactis<\/em> IDCC 4301 enhanced the production of short-chain fatty acids, which are essential for efficient energy production and utilization.<\/p>\n\n\n\n This may help dogs burn dietary energy more effectively and reduce the amount stored as fat. When energy is used efficiently, excess calories are less likely to be converted into body fat, which can help limit weight gain.<\/p>\n\n\n\n E. faecium<\/em> IDCC 2102 was also found to promote dopamine production, which may help restore normal feeding behavior in dogs. This is particularly important because abnormal overeating behavior and glucose intolerance in obese animals have been linked to disruptions in dopamine signaling.<\/p>\n\n\n\nProbiotics and Canine Obesity<\/h2>\n\n\n\n
