Diabetes is a very common chronic disease in the population, and the number of diabetic patients is increasing year by year, and there is a trend of younger people. Actually, it's not just humansDogs can also develop diabetes.
Diabetes is caused by problems with the body's secretion or use of insulinDiabetics who do not have ** will have high blood sugar levels.
In addition to regular physical examinations, we don't seem to have a better way to detect your dog's blood sugar, but early diagnosis is positive for the disease, so we can judge whether your dog has diabetes by observing your dog's symptoms and see a doctor in time**.
Here are 10 common symptoms of diabetes in dogs:
1.Increased urination output:
You may find that your dog is urinating more at a time than before, or that it urins more often (polyuria), which is why many parents bring their dog to the doctor.
Polyuria is caused by the overflow of glucose from the blood into the urine, and the body's water will go to the place where the osmotic pressure is higher, so the urine output of the dog with diabetes will increase significantly.
2.Increased amount of water to drink:
Increased water intake (polydipsia) is associated with increased urination, because as dogs produce more and more urine, they start to become dehydrated, so they drink more and more water to rehydrate their bodies.
3.Appetite:
Dogs with diabetes may experience polyphagia, which veterinarians attribute to an imbalance in insulin, a hormone produced by the pancreas that helps control blood sugar. Due to the lack of insulin, the body cannot perceive that it has glucose, so it thinks it is hungry and always wants to eat. 
4.Weight loss:
When your dog's appetite is normal or even increasing, but weight is losing (either gradually or suddenly), this can be a sign of diabetes.
As insulin decreases or resistance prevents glucose from being delivered to the brain, heart and other vital organs for energy, the body begins to break down muscle and fat in favor of these proteins and fats, leading to weight loss.
5.Cataracts:
Up to 80% of dogs with diabetes will eventually develop some degree of cataract, which is one of the most common long-term complications in diabetic dogs.
In healthy dogs, the lens absorbs glucose from the eye fluid and converts the excess glucose into sorbitol, which is produced when there is a large amount of glucose.
Sorbitol has a strong attraction to water, so water enters the lens, causing the fibers to distort and block the passage of light, which can cause your dog's eyes to look "cloudy". 
6.Vision loss:
Dogs with diabetes are at increased risk of blindness due to the formation of cataracts.
Cataracts completely prevent light from reaching the retina at the back of the eye, which can lead to blindness.
Blindness (and cataract formation) can last from weeks to months, or 24 hours, and it can also occur in the early or late stages of diabetes.
7.Coarse coat:
Diabetic dogs that have not been ****** tend to have poor coat and **quality.
Because when the body doesn't get the nutrients it needs because insulin doesn't work, and dogs become chronically dehydrated due to increased water loss in their urine, their coat will start to lose its luster and start to develop dandruff and dry, scaly**.
8.Vomiting:
Vomiting does not usually occur in simple cases of diabetes.
If diabetes is left untimely**, the dog may develop diabetic ketoacidosis (DKA) with vomiting, lethargy, and loss of appetite, which is an emergency and requires hospitalization**.
9.Fatigue easily:
Some dogs with diabetes have less interaction with their families and fatigue more quickly after playing or walking.
Because when sugar is trapped in the bloodstream and cannot enter the tissues, the body loses the glucose it needs for energy.
In addition, high blood sugar can lead to electrolyte imbalances, including low sodium, low potassium, and low phosphorus, resulting in reduced nerve function.
10.Stiffness or weakness:
Dogs with diabetes can experience muscle weakness due to a lack of glucose in their muscles.
Another less common cause is diabetic neuropathy, which can cause chronic or progressive hind limb weakness, arthralgia, muscle wasting, and generalized weakness.
The above are the more common symptoms of diabetes in dogs, parents can learn to find the signs of diabetes in dogs, and communicate with the veterinarian can help you intervene as soon as possible, the sooner you do it**, the better the prognosis.
Diabetes in dogs is usually a controllable disease, early blood sugar management, most diabetic dogs can have a good quality of life, under the guidance of a veterinarian, can be fed [Adult dog diabetes prescription food].
High protein boosts muscle mass and stabilizes blood sugar throughout the day.
Low starch intake helps stabilize postprandial blood sugar.
