What to look for

Energy Needs

Portuguese Water Dogs require a diet rich in calories to support their high energy levels. Look for food with a balanced mix of protein, fat, and complex carbohydrates to provide sustained energy. A minimum of 25% protein and 15% fat is recommended to support their athletic build.

Joint Health

As a breed prone to hip dysplasia, Portuguese Water Dogs need a diet that supports joint health. Glucosamine and chondroitin are essential ingredients to look for, as they help maintain healthy joints and reduce the risk of degenerative joint diseases.

Digestive Sensitivity

Some Portuguese Water Dogs may have sensitive stomachs, requiring a diet that is easy to digest. Look for food with prebiotic fiber, probiotics, and novel protein sources to support a healthy gut microbiome.

Weight Management

Portuguese Water Dogs can be prone to weight gain, so it's essential to monitor their food intake and choose a diet that supports healthy weight management. A balanced mix of protein, fat, and complex carbohydrates can help maintain a healthy weight.
