Is my dog ​​drinking too much water?

Water is critical to the health of all living things, including dogs. Drinking too much or not enough can be a sign or cause of life-threatening problems.

How to recognize that your dog drinks too much

When you try to determine if your dog drinks too much, you should know how much to drink. A normal healthy dog ​​usually drinks between 20 and 40 ml of water per pound of body weight per day. This goes about:

  • 1 ½ cups to 2 cups for a 10-pound dog
  • 3 to 4 cups of water for a 20-pound dog
  • 6 to 8 cups for a 40-pound dog
  • 9-12 cups for a 60-pound dog
  • 12-16 cups for an 80-pound dog

The amount of water consumed also depends on several factors, including whether the dog eats dry food or eats canned food (canned foods contain more water), activity levels, sodium ingestion, exposure to warm weather, medications, fluid loss, such as vomiting or diarrhea. . and any disease that can cause excessive thirst.

Thus, as mentioned above, dogs usually consume between 20 and 40 milliliters per pound of body weight per day, or between 3 and 4 cups of water per day for a 20-pound dog. Anything more than this, under normal environmental conditions, is considered excessive drinking (also known by the medical term “polydipsia”).

Causes for dogs to drink too much water

There are several medical reasons for excessive drinking. The most common causes are:
Chronic renal failure also called chronic renal failure and commonly called CKD, is a common problem in dogs. This is most common in older dogs. When digesting food, waste is generated, which is delivered by the blood to the kidneys to filter and excrete as urine. When the kidneys fail, they can no longer remove these products, and the toxins accumulate in the blood, causing clinical signs of kidney disease. Symptoms may include increased thirst, increased urination, lethargy, vomiting, weight loss, bad breath, and weakness. Learn more about kidney failure (CRF) in dogs.

Diabetes mellitus, commonly known simply as “diabetes,” commonly referred to as “diabetes,” is a chronic disease in which a deficiency of the hormone insulin impairs the body’s ability to absorb sugar. Diabetes mellitus leads to the inability of the tissue to utilize glucose. The disease is caused by high blood sugar levels, inadequate delivery of sugar to the tissues and changes in the body’s metabolism. The most common symptoms are increased thirst, increased urination, weight loss, and lethargy. Learn more about diabetes in dogs.

Pyometra, the medical term used to describe an infected uterus, can be open (draining pus from the vagina) or closed (pus is contained in the uterus using a closed cervix). Common symptoms include lethargy, loss of appetite, vomiting, diarrhea, drinking excessive amounts of water, and frequent urination. Learn more about uterine infection (called pyometra).

Acute renal failure, also known as acute renal failure and commonly referred to as “ARF”, is characterized by a sharp decline in kidney function, which leads to changes in the chemical composition of the body, including changes in fluid and mineral balance. Changes that occur as a result of ARF affect almost every body system and are usually caused by toxins. Common symptoms include vomiting, loss of appetite, weight loss, lethargy and changes in water consumption. Learn more about acute renal failure in dogs.

High blood calcium, also known as hypercalcemia, refers to an abnormally high concentration of calcium in the blood. There are many different causes, including cancer. Learn more about hypercalcemia in dogs.

Cushing’s disease, a relatively rare endocrine system pathology, is also known by the medical term hyperarenocorticism. This is a painful condition in which hyperactive adrenal tissue produces an excessive amount of cortisone. Cortisone and related substances are indispensable hormones of the body, but when they are produced in excessive quantities, these substances can cause systemic diseases.

Diabetes insipidus arises from the inability of the tubules of the kidney to properly absorb water. This is an unusual condition in dogs caused by a disturbance in the production of a hormone called ADH (an antidiuretic hormone) from the brain (central DI), or a violation of the ability of the kidney to respond correctly to ADH (nephrogenic DI). Symptoms include strong urination accompanied by increased thirst.
