Soluble fiber helps chronic large-bowel diarrhea in police dogs

Abstract

BACKGROUND: Chronic intermittent or persistent diarrhoea is a common condition in dogs and may be a reflex of gastrointestinal or non-gastrointestinal disorders. Besides diarrhoea, many athletes experience other gastrointestinal symptoms. Dietary fiber can help normalize colonic motility and transit time, support normal gastrointestinal microflora growth and provide fuel for colonocytes. This study aimed to evaluate dietary supplementation effectiveness with psyllium husk in police working dogs with chronic large-bowel diarrhoea. Twenty-two animals were selected. Concurrent conditions were ruled out through complete blood count and serum biochemistry. Fecal Clostridium and Salmonella were also screened. A soluble fiber, psyllium husk, was added to the diet at the dose of 4 tablespoons/day for 1 month. A daily log of fecal characteristics (type, frequency, and color) was maintained during the supplementation month and for an additional month, without supplementation. RESULTS: Response to treatment was classified as "very good" in 50% of animals, "good" in 40% of animals, and "poor" in 10% of cases. During the month of psyllium husk supplementation, defecation frequency decreased from 3.5 to 2.9 times a day, with 90% of animals showing consistent stools regularly and registering a mean increase of 2 kg in body weight. Beneficial effects were still observed during the second month, without psyllium husk supplementation. CONCLUSION: Psyllium husk can be useful in the management of chronic large-bowel diarrhoea in working dogs, which exhibited lower defecation frequency, improved stool consistency, and gained weight. Effects were felt beyond the supplementation period. Alternative approaches for non-responsive cases need to be evaluated.
