As a first aid measure, this product has proved an exellent, fast acting tonic for off colour dogs who aren't interested in drinking or eating - a dose appropriate to the dog's weight via the dispenser has been of significant help in getting them drinking again very quickly, thus preventing dehydration, and improved appetite enough to ensure adequate food intake. Especially useful for puppies and dogs that have exhausted themselves- would add though that if symptoms persist, seek veterinary help, but as a first call, nutri-drops are well worth having to hand in the dog's 'first aid' box!
