Symptoms of Diabetes in dogs and cats:
-Loss of appetite
-Excessive drinking and urination (PUPD)
-Loss of muscles and weakness
-Depression and lethargy
-Unkempt haircoat and dandruff
*On a personal note: my dog started wetting the bed at night, he was diagnosed with diabetes when he was 8 years old. After proper diet, exercise and regulated insulin injections, he lived a long happy life.
Routine blood work can determine if your pet is a diabetic. Consult your veterinarian.
