The objectives were to evaluate the effects of a liquid nutritional supplement formulated for dogs on water intakes and urine output. A liquid nutritional supplement was tested by way of a cross-over design in 8 experimental healthy Beagle dogs (4 males and 4 females, aged 9.3 years). The supplement (87 percent water, 2.7 percent protein, 2.6 percent fat, 0.4 percent crude fiber) was added to water and tested at 2 incorporation rates (50 or 70 ml/day/dog—D50 or D70) versus the control placebo (CO-water only). The dogs were kept in a controlled environment; water intakes and urine output were measured. Individual water intakes were characterised by large variations. Mean water intake increased significantly by 28 percent in dogs receiving the liquid nutritional supplement, in both genders, irrespectively of the dosage. Urine output was also increased, by 55 percent. Faeces scores remained unchanged. It was concluded that the liquid supplement increased water intake and urine output in a safe way, without increasing dramatically the daily dietary sodium chloride intake. The recommended dosage of the manufacturer—50 ml/day for dogs weighing 10 - 20 kg BW is efficient. Increasing the dosage had no advantage, nor adverse effects. Increased water intake and urine output is of interest for dogs suffering from urolithiasis.
