All dogs can benefit from probiotics, which aid digestion and modulate the immune system. Probiotics produce short-chain fatty acids (SCFAs), which inhibit the growth and activity of harmful bacteria, such as E. coli, Salmonella, and Clostridium perfringens, as well as providing other benefits to the intestines. Human studies have documented the effectiveness of certain strains in treating diarrhea, irritable bowel, and intestinal inflammation (fewer studies have been conducted on dogs). Probiotics may help prevent urinary tract infections, and can even reduce allergic reactions by decreasing intestinal permeability and controlling inflammation.

 

Species with specific strains known to benefit dogs include Enterococcus faecium (strain SF68) and Bacillus coagulans. Bifidobacterium animalis (strain AHC7) has been shown to reduce the time for acute diarrhea to resolve in dogs. Certain strains ofLactobacillus acidophilus improve frequency and quality of stools in sensitive dogs.Lactobacillus rhamnosus strain GG (LGG) is effective in preventing and treating diarrhea in humans, and may benefit dogs as well. Probiotic products may contain one or several strains.
