- Product Details
Logic Firm was previously branded as Logic Diar-stop.
Logic Firm is a highly palatable digestive support supplement. It is formulated for cats and dogs to manage digestive upsets. Logic Firm contains Montmorillonite, Electrolytes and Dextrose – these ingredients are key to helping restore normal digestive function. These three ingredients work together to coat the intestinal lining, absorb toxins, restor electrolytes and provide energy. Logic Firm also contains prebiotics called fruco-oligosaccharides. These prebiotics promote growth of good bacteria such as bifidobacteria and lactobacilli to help maintain normal intestinal flora. They also help to rid the intestinal tract of any potentially pathogenic bacteria.
Logic Firm also encourages the production of short chain fatty acids (SCFA's) called acetate, butyrate and propionate. These three SCFA’s are important energy sources for the large intestine.
Logic Firm is available in three different sizes to suit every breed of dog.
Administer orally for 3 days, or as recommended by your veterinarian. Follow the dosage instructions on the box.
