psyllium (Plantago psyllium) is a fiber generally used as a supplement in the treatment of diseases that led to constipation. To understanding of the effects of this fiber in dogs, two experiments were conducted. The first evaluated in healthy dogs a diet supplementation with 0%, 2% and 4% of ground whole psyllium seeds (as-fed basis). Eight adult Beagle dogs were used. They received the experimental diets for eight days. A linear increase of faecal moisture was verified with the addition of psyllium (R²=0.54 and P=0.0012), with no alteration on faecal score or number of defecations per day. The second experiment included 24 dogs with constipation. The dogs received a diet supplemented with 2% of psyllium as part of the treatment, and the owners were invited to answer a questionnaire. Nineteen (79.2%) owners reported that their dog had an easier defecation process during supplementation. Fifteen (62.5%) reported that the animals´ faeces, which were dry or hard at the start, became normal or pasty after psyllium consumption. The results confirmed a laxative effect of psyllium in dogs, which was already reported in human medicine, supporting the use of this fiber in the clinical management of diseases that cause constipation in dog.
