Cane Corso nutrition: muscle, puppy growth and bloat

For a Cane Corso the two feeding decisions that carry the most risk are how fast the puppy grows and how the adult eats its meals. Rapid growth and excess calcium strain developing joints in large breeds, and meal size, eating speed and bowl height have all been linked to bloat. The American Kennel Club standard puts males at 25 to 27.5 inches (64 to 70 cm) at the shoulder and females at 23.5 to 26 inches (60 to 66 cm), with weight in proportion to height and a life expectancy of 9 to 12 years.

Daily calories

The figures below use the formulas in the Merck Veterinary Manual. Resting energy requirement is 70 × (body weight in kg) raised to the power 0.75, multiplied by a factor for age and neuter status. For a dog this size the result is a first estimate. Dogs of the same weight differ widely, and a Corso doing regular protection or tracking work will need more than a house guardian.

Puppy figures are for the current weight and rise as the puppy grows. Weigh the dog monthly and judge the body by hand: ribs easy to feel under a thin layer of fat, a waist from above, and a tuck behind the ribs from the side. Ribs and hip bones that stand out mean the dog is too thin. Ribs that cannot be felt at all mean it is too heavy.

Protein, fat and muscle

A Corso carries a lot of muscle, and a complete and balanced adult food supplies the protein to keep it. There is no evidence that this breed needs a special protein percentage, a particular number of meat sources or added leucine. What matters more is that the food meets a recognized nutrient profile for the dog's life stage and that the portion keeps the dog lean. Muscle that disappears while the dog is eating normally, especially over the back and hindquarters, is a reason for a vet check rather than a richer food.

Energy-dense, high-fat foods make overfeeding easy in a dog this size. For a breed whose elbows and hips are already at risk, excess weight is the more usual problem, not too little fat.

Controlled growth in puppies

Large and giant breeds grow fast from weaning to about a year, and that is when diet can hurt their joints. The Merck Veterinary Manual notes that excess calcium causes more severe osteochondrosis and poorer bone remodeling in young, rapidly growing large-breed dogs than in dogs fed lower amounts. Those signs have not been reported in small or slower-growing breeds fed the same high amounts.

• Feed a food labeled complete and balanced for growth, including the growth of large-size dogs.
• Give no calcium, bone meal or vitamin D on top of it.
• Feed to a lean body shape rather than to the top of the growth curve. A puppy can reach its adult size slowly without losing any of it.
• Split the day's food into three or four meals while young, then at least two.

Joint risk is real in this breed. A French study of more than 17,000 elbow x-rays across 13 breeds found the Cane Corso among the four breeds most often affected by elbow dysplasia, alongside the Dogue de Bordeaux, Rottweiler and Bernese Mountain Dog. Parents with hip and elbow scores, and a lean puppy, are the practical defenses.

Bloat and how meals are served

Gastric dilatation-volvulus (GDV) happens when the stomach fills with gas and twists. It cuts off blood supply and can kill within hours without surgery. Deep-chested large breeds are at high risk, and most of what is known about prevention comes from studies of those breeds.

• Smaller meals. In a five-year study of high-risk breeds, dogs fed a larger volume of food per meal had a higher risk of GDV regardless of the number of meals, and the risk was highest when that large volume came once a day. Two or three smaller meals keep the volume down.
• Slower eating, bowl on the floor. A prospective study of 1,637 large and giant dogs linked faster eating and a raised feeding bowl to more GDV, along with older age and having a parent, sibling or offspring that had bloated. Raised bowls were once recommended to prevent bloat. The data point the other way.
• Check where fat sits on the label. In a case-control study, dry foods with an oil or fat among the first four ingredients carried a 2.4-fold higher risk. It was an unexpected finding from one study, not proof, but it costs little to act on.
• Quiet time around meals. Hard exercise straight after a big meal is a common-sense thing to avoid, though the studies above do not report on it.

Inherited conditions and the heart

One inherited disease has been described in this breed in particular. Dental-skeletal-retinal anomaly (DSRA) gives affected dogs brittle, discolored, translucent teeth, disproportionate growth and a retinal degeneration that leads to blindness. In 2021 researchers traced it to a recessive splice defect in the MIA3 gene, a gene involved in exporting collagen from cells, which means parents can be DNA tested. No diet affects it.

Dilated cardiomyopathy (DCM), a weakening and enlargement of the heart muscle, is often raised with owners of large breeds because of diet. In July 2018 the FDA began investigating DCM reports in dogs eating certain foods, many labeled grain-free and high in peas, lentils, other legumes or potatoes. The agency has said that adverse event reports alone do not establish a causal link, and in December 2022 it said it would release no further public updates until it had meaningful new scientific information. A cautious owner can choose a food that does not lean heavily on pulses or potatoes. There is no published evidence that the Cane Corso is especially prone to diet-associated DCM, and there is no evidence that adding taurine or L-carnitine to a complete diet helps a healthy dog. A new heart murmur, fainting, a cough or reduced stamina needs a vet exam.
