Sussex Spaniel Ideal weight range
16–20.5 kg
Sussex Spaniels have a breed-specific predisposition to pyruvate dehydrogenase deficiency, a rare inherited metabolic condition that impairs the body's ability to convert nutrients into energy efficiently. Affected dogs may show exercise intolerance and variable weight despite normal food intake, making consistent tracking a useful tool for identifying when energy metabolism is not functioning as expected.
Your dog is more than a breed average.
A generic range is just a starting point. FitFido uses your dog's unique breed characteristics, age, body type, and activity level to calculate their target weight and construct a custom plan that adjusts as you progress.
Please note that a dog's ideal weight depends on many individual factors, including height, bone structure, and overall body condition.
