Signs of Hyperglycemia in Chihuahuas

Signs of hyperglycemia, or high blood sugar, occur when your Chihuahua's body does not use glucose properly. It is more common in pets that are overweight and in middle-aged dogs, but can occur anytime and often results in diabetes. Although the diagnosis of hyperglycemia is frightening, it does not have to be. According to Vet Info, diabetic dogs nearly always require insulin. Once recognized, you can treat diabetes successfully.

  1. Thirst

    • Excessive thirst is one of the first noticeable signs of hyperglycemia in a dog. Sometimes your diabetic Chihuahua will literally lie by the water dish and drink almost continually.

    Frequent Urination

    • As expected, from drinking all that water, frequent urination may become a problem. Your Chihuahua may begin urinating in the house, when he never did before. She may ask to go out much more often and more urgently. Her body is attempting to get rid of the sugar. Because of frequent urination, your dog may become dehydrated. Although he drinks plenty of water, it just may not be enough to keep up.

    Weight Loss with Increased Appetite

    • Although your dog's appetite is good and he is always anxious to eat, his weight may be dropping. This sign of hyperglycemia in Chihuahuas may be serious. Because his body cannot use the food for energy, he becomes extremely hungry. A dog that eats well and still loses weight should see a vet quickly.

    Cataracts

    • The World Small Animal Veterinarian Association states that it is common for diabetic dogs to develop cataracts. Sometimes, a Chihuahua's diminishing sight is the first indication that the owner notices.

    Lack of Energy

    • As your dog uses up muscle mass and is unable to utilize the sugar for energy, he may become sluggish. In severe cases, your dog may lose interest in his surroundings and become depressed.

    Less Noticeable Signs

    • Dogs can develop neuropathy due to consistently high blood sugar levels. This most often affects the hind legs and you may notice he is no longer able to jump or climb as he used to. Diabetic dogs often develop matted fur and scaly skin. These conditions should improve when sugar levels are controlled. Vomiting and liver disease may also occur. The Pet Care Guide notes that bacterial infections may be frequent among pets with poor control of sugar.
