One of the recognised obesity-related conditions in dogs is lower urinary tract disease.6 

Overweight dogs have more than twice the risk of developing calcium oxalate (CaOx) uroliths compared with dogs of ideal body weight.7 We also know from a recently published study that morbidly obese dogs have a higher prevalence of asymptomatic urinary tract infection (UTI).8 Given struvite uroliths are most often caused by UTI in dogs, morbidly obese dogs could be at increased risk for struvite uroliths.

Hill’s has combined the proven technology of Metabolic & c/d Multicare Canine to help effectively manage overweight/obese dogs with these common urinary disorders.

How do you manage your struvite urolith cases? Jump to cut? Or try diet first?

If you jump in to remove suspected struvite uroliths surgically, perhaps you should take a look at The American College of Veterinary Internal Medicine (ACVIM)  consensus statement on urolith management.  This is an excellent resource that outlines several recommendations and standards of care for dogs and cats with lower urinary tract uroliths.  One key ACVIM recommendation is that uroliths consistent with a composition of struvite should be medically dissolved with the following rationale…


Medical dissolution for both sterile and infection-induced struvite uroliths is highly effective and avoids the risks and complications of anaesthesia and surgery. In many cases, dissolution is less expensive than surgery. Sterile struvite urocystoliths usually dissolve in less than 2–5 weeks. Avoiding cystotomy and closure of the bladder with sutures will eliminate the risk of suture-induced urolith recurrence, which may be responsible for up to 9% of urolith recurrences. Although some believe that medical dissolution places the patient at high risk for urethral obstruction, this complication has not been reported in the veterinary literature and is likely to occur with the same frequency or less frequently than when attempts at surgical removal are incomplete.”9. p.1565-6


There are also many other pertinent recommendations such as not substituting high‐sodium dry foods for high‐moisture foods and considering the use of potassium citrate or other alkalinizing citrate salts for dogs and cats with persistently acidic urine. You can access the full consensus statement here.

Need a refresher on how Hill’s™ Prescription Diet™ Metabolic works?

Did you know that Hill’s Metabolic works differently to all other traditional (low calories and fat, increased fibre) calorie counting diets?


Through break through research in our Predictive Biology lab, Hill’s scientists have identified the gene expression patterns associated with obesity in dogs and cats. Put simply, weight gain changes gene expression.  Many different gene expression pathways are affected including key pathways of inflammation, insulin sensitivity, amino acid and fat metabolism and appetite control.

Metabolic is formulated with a blend of natural ingredients specifically selected based on their ability to change the UNHEALTHY metabolism of overweight pets to be more like the HEALTHY metabolism of lean pets. This blend includes coconut oil, phytonutrients and antioxidants from fruits and vegetables, controlled amounts of high quality protein along with a healthy mix of soluble and insoluble fibre that help activate a pet’s metabolism and puts them in “fat-burning” mode, activating the body’s natural ability to burn excess body fat and affect calorie utilisation.
