Logic Diar-stop (Previously Diarsanyl Plus)
Diar-Stop is a pharmaceutical grade formulation which helps manage digestive upsets in dogs and cats when the intestines become irritated.
This can be caused by a sudden change in diet or by eating inappropriate food e.g. scavenging, on a walk or eating from the rubbish bin.
Diar-Stop has an easy-to-use syringe and palatable formula that uses Montmorillonite (Coats, protects the intestinal lining/ absorbs toxins), Sodium Magnesium Potassium (to help restore electrolytes lost through diarrhoea), Dextrose (provides an energy source for the small intestine) and Prebiotics (FOS fructo-oligosaccharides) to restore the normal bacterial flora.
