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.

With 4 German Shepherds to care for, we always keep a couple of tubes of Diar-Stop in the cupboard, and use it at the first sign of diarrhoea. A good product that seems to work well. Easy to administer, as the dogs will take it on top of their food or will even lick it off a spoon.
I haven't used this particular tube yet as it's back-up for emergencies! I have used this brand and product before and it works wonders when my German Shepherd has diarrhoea!
Great product firms the stools well without any side effects on the dog. My vet recommends this product but obviously it is more expensive buying from the vet.
