Miniature Schnauzers are prone to diabetes, bladder stones and pancreatitis, which, by avoiding a diet high in sweet or fattening food, can often be avoided.

Schnauzers with uncropped ears are prone to ear infections and deafness later in life if the ears are not checked regularly or dried out after swimming.

Obesity

Perfect weight varies on what size the dog is; if the dog is 14 inches high, then the perfect weight would be 14 lbs. They should not be overfed since they gain weight easily.
