Excessive thirst and frequent or uncontrolled urination are often signs of kidney problems or diabetes. Inappropriate urination may be a sign of incontinence caused by a hormone imbalance, which is most common in spayed females, or caused by other medical conditions. Your veterinarian should be contacted if you notice incontinence in your dog. An older dog is more likely to develop tooth and gum disease. Because of sore gums or loose teeth, he may let food drop out of his mouth or even refuse to eat.
Dogs are susceptible to heart disease.
Coughing, difficulty in breathing and tiredness could indicate possible cardiac problems. A hazy, bluish cast on your aging dog's eyes is normal and usually does not hinder the eyesight. However, the hazy, whitish growth of cataracts can lead to blindness. Your veterinarian can help you distinguish the difference. Like humans, a dog's metabolism slows down as he gets older.
