The kidneys in dogs are bean-shaped organs that play a vital role in filtering waste and excess fluids from the blood.
Located in the abdominal cavity, each kidney is connected to the bladder by a ureter, which carries waste urine away from the body.
The kidneys are surrounded by a network of blood vessels that help them filter waste and excess fluids from the blood.
Each kidney is made up of millions of tiny units called nephrons, which filter waste and excess fluids from the blood and produce urine.
The kidneys are responsible for removing waste and excess fluids from the body, regulating electrolyte levels, and producing hormones that help control blood pressure.
The kidneys also help to regulate the body's acid-base balance by removing excess hydrogen ions from the blood.
The kidneys are a vital part of a dog's overall health and function, and understanding their anatomy can help pet owners provide better care for their furry friends.

Kidney Functions
The kidneys are the unsung heroes of the canine body, working tirelessly to keep your furry friend healthy and happy. They're responsible for filtering waste products and excess fluids from the blood, ensuring that your dog's body remains hydrated and functioning properly.
Each kidney contains hundreds of microscopic filtering units called nephrons, which are capable of forming urine on their own. This is a remarkable feat, especially considering that a single kidney can still support a normal, healthy life for your dog.
The kidneys play a crucial role in regulating the body's acid-base balance, or pH levels. They do this by either retaining or losing certain ions, such as hydrogen, to maintain a delicate balance.
By regulating salt levels through the production of renin and other substances, the kidneys help keep blood pressure in check. This is a vital function, as excessive salt retention can lead to high blood pressure.

The kidneys also have a hand in hormonal functions, secreting a hormone called erythropoietin that stimulates the production of red blood cells. This is essential for maintaining healthy oxygen levels in the body.
Here's a breakdown of the kidneys' key functions:
- Filtering waste products and excess fluids from the blood
- Regulating the body's acid-base balance (pH levels)
- Regulating salt levels to maintain healthy blood pressure
- Producing erythropoietin to stimulate red blood cell production
The kidneys' ability to filter waste and excess fluids is a remarkable process, involving the removal of unwanted substances from the blood and the reabsorption of necessary ones. This process is crucial for maintaining your dog's overall health and well-being.
Urinary System Components
The urinary system in dogs is made up of several key components, each playing a vital role in the process of filtering waste and excess fluids from the blood.
The kidneys are the primary organs responsible for filtering waste and excess fluids from the blood, and they're located in the abdominal cavity under the backbone.
The ureters are thin tubes that extend from the kidneys to the urinary bladder, carrying urine from the kidneys to the bladder in small spurts.

The bladder is a collapsible muscular organ shaped like a balloon that provides a means for temporary urine storage, and it's held in place by ligaments attached to other organs and the pelvic bones.
The urethra is the tube that carries urine from the bladder to the outside, and in male dogs, it terminates at the tip of the penis, while in female dogs, it's much shorter and wider, and opens just in front of the opening of the vagina.
The nephrons are microscopic filtering units within the kidneys, each consisting of a glomerulus and a renal tubule, and they're responsible for removing urea and other waste products from the blood to produce urine.
The sphincter is a circular muscle that controls the outlet opening of the bladder, preventing urine from leaking out until the bladder reaches a certain point of distention and the animal voluntarily relaxes the sphincter to release urine.

Urinary System Issues
Kidney stones are a common problem in dogs, and they can be caused by a variety of factors, including diet and genetics.
Dogs with kidney stones may exhibit symptoms such as vomiting, abdominal pain, and blood in the urine.
The kidneys are responsible for filtering waste and excess fluids from the blood, and kidney stones can block this process.
Dogs with kidney disease may experience weight loss, increased thirst and urination, and pale gums.
Regular check-ups with a veterinarian are crucial to detect any potential urinary system issues early on.
Kidney disease can be caused by chronic kidney damage, which can lead to the loss of kidney function over time.
