Things to keep an eye on

Bloat (GDV)

high

Large, deep-chested breeds are more prone to gastric dilatation-volvulus, where the stomach fills with gas and may twist. This is a serious condition that requires immediate veterinary attention if observed.

Feed your dog smaller, more frequent meals rather than one large meal per day to help digestion.

Hip Dysplasia

high

This is a common orthopedic condition in large breeds where the hip joint does not fit together perfectly, potentially leading to discomfort. It is often influenced by both genetic factors and growth rates.

Maintain a lean body weight throughout your dog's life to reduce unnecessary stress on the joints.

Obesity

moderate

Excess weight can place significant strain on the skeletal system and internal organs of large breeds. Monitoring caloric intake is vital for preventing weight-related health complications.

Measure food portions accurately and limit high-calorie treats to ensure your dog stays at an ideal body condition.

General patterns, not a diagnosis — always check with your vet.
