Urine problems are fairly common in quadrupeds, so it is important to support your dog with appropriate diet food. Urinary S/O Ageing 7+ is specially formulated diet food to support the urinary tract for dogs with age-related problems aged 7 years and older. The dry food is specially formulated to dissolve urinary crystals. A common cause of urinary tract problems is the formation of bladder stones, such as struvite. Urinary S/O Ageing 7+ supports your ageing dog and helps reduce the formation of new bladder stones. The food provides increased fluid intake, which increases urine. This reduces the concentration of crystalline components in the urine, keeping the urinary tract healthy. By always offering enough water to your four-legged friend, he will urinate out any crystals again.
