You may have never heard of urine infection in pets, but the truth is that this is a very common evil That happens continuously. Its symptoms may lead us to believe that our animal simply has behavioral problems.
This may mean that we do not give much importance to the matter, so we believe it is vital that you learn the causes, symptoms and treatments of urine infection in dogs.
What is canine urine infection
The first thing to know is that as a general rule, this can happen to any dog. However, those who are neglected or who live on the street have a better chance of suffering it.
Well, the urinary system is responsible for discarding toxins and other waste that our body does not need. Therefore, when you do not urinate enough, these residues can accumulate in the urinary ducts, blocking them and producing a urine infection.
Causes of urine infection
Urine infection can have several causes such as kidney stones, tumors, excessive humidity and others. It is usually caused by the bacteria Escherichia coli in dogs, although it can also be affected by fungi and other bacteria.
In the case of dogs, Many more cases are known in females because the urethra is shorter and wider, which facilitates the entry of bacteria and parasites. In addition, they urinate much less than males, thus allowing urinary duct obstruction.
This infection, although it is common, should not be taken for granted, as it could go to the blood and cause major problems in the animal. Therefore, it is necessary to be well informed about the symptoms.
Symptoms of urine infection
Recognizing what happens to our pets is not always easy, because they do not have a communication contact as direct as speech. However, their body and body language always tell us in one way or another, implying what they may be suffering.
How to know if our dog has a urine infection? These are some of the symptoms. Stay tuned for your pet:
- Urine that smells worse than usual
- Blood in the urine
- Cloudy urine
- Efforts to urinate without results
- Little Cant>
If you see one or more of these symptoms in your dog, take him to the vet. This can determine if it is an infection through a urine sample. You will be prescribed antibiotics and in case they do not work, a urine culture will be performed.
This consists of introducing a small tube through the urinary system that will allow concise identification of what type of fungus or bacteria is causing the infection to find the right treatment.
Home remedies for urine infection
Although if you are one of those who prefer home remedies, you can also try some. Although you should not postpone the visit to the veterinarian for it. Remember that your pet is a living being and deserves the best care.
These are some of the most effective, but if you don't notice improvement in one or two days, please go to the vet:
Causes of urinary infection
There are many causes that cause this evil to our friends, the most common being the intake of contaminated water or food, stones or crystals in the bladder or urethra, cancer, inflammation or infection of the bladder, or even stress.
In any of these cases, you should know that the occurrence of urinary tract diseases usually appear after seven years of age, which is when dogs tend to start having more difficulty controlling the urinary sphincter. But that doesn't mean they can't appear before. Whenever we suspect that the animal has a urine infection, regardless of its age, we must take it to the vet.
Symptoms of urine infection
The most frequent symptoms, the ones that should worry us a lot, They are as follows:
- Almost yellow yellow urine
- Presence of blood or pus in the urine
- The animal complains when it needs> Treatment
Veterinary treatment is vital for the dog to lead a normal and happy life again. It will be he who makes a diagnosis and, depending on the cause, will put a treatment or another. Usually it will consist of administer antibiotics, and make changes in the diet, giving it a feed specially made for dogs with urinary infections.
You will see how, little by little, it is again what it was 😉.
What is a urinary tract infection? What causes it?
Urinary tract infection mayoccur randomly in any dog However, those who suffer from poor diet or care, immunosuppressed dogs, are likely to get it more easily.
The urinary system allows the body to properly eliminate toxic and disposable substances that the body does not need. This system, formed by the kidneys, ureters and urethra, then allows us to get rid of what we don't need.
Urinary tract infections are caused by microorganisms They lodge in the urinary tract. They can stay in our dog's organism if it comes into contact with a sick dog but they can also develop on their own. For example: dogs that do not urinate often enough are susceptible to a urinary tract infection because the bacteria that should be evacuated go up to the bladder.
Finally we warn that it can happen that certain diseases cause urinary infections. The appearance of hormonal changes, tumors, stones, excessive humidity or many other conditions can cause a urinary infection.
The urinary infection receives different technical names according to the zone in which it is located, as follows:
- Urethral infection: urethritis
- Bladder infection: cystitis
- Prostate infection: prostatitis
- Kidney infection: nephritis or pyelonephritis
The most frequent bacteria in urine infection
The bacteria that most frequently cause urinary infections in dogs is the Escherichia coli. However, others genera of bacteria which are also frequent are: Staphylococcus, Proteus, Enterococcus, Klebsiella, Streptococcus, Enterobacter, Chlamydia Y Pseudomonas.
Although bacteria are the most frequent pathogens in these infections, the urinary tract of dogs can also become infected with fungi, mycoplasmas, viruses, algae and worms parasites
Urinary infections are more frequent in females, because their urethra is shorter and wider, and they urinate less frequently than males. This facilitates the entry of pathogens and colonization of the urinary bladder. However, infections in males, although less frequent, are more difficult to treat, since antibiotics have less access to places where bacterial colonies form, especially when prostatitis has occurred.
When the infection is not treated properly, there is a risk that the bacteria pass into the bloodstream causing sepsis that can be fatal, or that infect other organs.
Symptoms of urinary tract infection in dogs
In many cases the symptoms they can be difficult to detect and it is common for the infection to come to light during a visit to the veterinarian for different causes. In other cases, the symptoms are more evident. The most common symptoms of urinary tract infection in dogs are:
- Increase in how often the dog urinates.
- The dog urinates little cant>
Diagnosis of a urine infection
The diagnosis of urinary infections is made through the clinical symptoms and the urine analysis. When necessary it is also done a urine culture. All these procedures must be carried out by a professional. Even if you think that your dog has obvious symptoms of a urine infection, you can overlook an illness that caused this situation.
The urinalysis is done using a test tape that is introduced into the urine sample. With this you can know the pH of the urine, the levels of proteins, ketones, glucose, bilirubin, nitrates and other substances indicating the function of the organs. The clarity of urine, its color, smell and general appearance are also evaluated. In addition, a sample is observed under a microscope to see if they exist fungi, bacteria, white blood cells or other infection indicator elements.
The urine culture is necessary to know the specific bacterium that causes infection. It is more used when initial treatment with broad-spectrum antibiotics does not work. In cases where stones, prostate inflammation or other obstructive or structural problems are suspected, radiographs and ultrasound are usually used.
Treatment of urine infection in dogs
The treatment for bacterial urinary tract infections is the administration of antibiotics. Generally used broad spectrum antibiotics they give good results, but in cases where they do not work, antibiotics specific to the bacteria causing the infection should be administered.
It is important to administer the prescribed antibiotic all the time that the veterinarian has indicated, even if the symptoms disappear before.
Non-bacterial infections are treated with other medications, such as fungicides and antiparasitic. When there are obstructions caused by stones or prostatitis, these problems should be treated at the same time as the infection. In addition, the veterinarian will recommend a diet that allows restore pH normal urine, which becomes alkaline during infection.
The prognosis depends on the complication of the infection, as well as on the causative agents. Simple infections caused by bacteria usually have an excellent prognosis. In contrast, fungal infections are more difficult to treat. The most complicated urinary infections have a variable prognosis, depending on each case.
Urine infection prevention
To prevent urinary tract infections in dogs it is important to allow the dog frequent urination and always have available clean fresh water to drink. This helps to eliminate bacteria from the urethra.
The frequency with which the dog urinates is usually the most common cause. Bacteria cannot be dragged outside unless the dog urinates frequently. This situation occurs, for example, when the dog remains too long locked up, or when it suffers from diseases that disable it to move properly, such as osteoarthritis (osteoarthritis) and, therefore, is reluctant to move.
For dogs that are predisposed to develop urinary tract stones, the veterinarian may recommend some specific diet that reduces the formation of these structures. The pH of the dog's urine (the degree of acidity or alkalinity of the urine) is influenced by feeding. A diet that alkalizes urine facilitates the onset of infections.
Emergence of anemia due to urinary infection in dogs
Dogs suffering from urine infection due to kidney problems They are susceptible to the appearance of anemia due to urinary infection. That is mainly due to a low production of erythrocytes. Anemia can also be caused by bacteria Escherichia coli or by mycoplasmas like Mollicutes. In any case it will be essential go to the vet to determine the cause of anemia.
You can know if your dog has anemia checking your mucous membranes (in eyes, mouth, sex or anus), which should be pink. If they are excessively pale and even white, your dog may suffer from anemia.

How does a dog's urinary tract work?
The urinary tract of dogs is made up of kidneys, ureters, bladder, urethra and, in
The males, prostate. The kidneys are responsible for filtering the blood to clean it
of toxins that are going to be transferred through the ureters to the bladder.
The kidneys maintain the balance between fluids and electrolytes in the body. A urine infection in dogs originates when pathogens, especially bacteria, spread through the urinary tract, leading to different symptoms.
These infections will be low when they affect the bladder, prostate or urethra and high when they reach the kidney. That is, they can be less or more serious, but they always require veterinary treatment.
What are the symptoms of a urinary tract infection?
If our dog suffers an infection of this type, it is usual to present the following
- Painful urination: urination is difficult. The dog licks its genitals, makes
force, groan, evacuate very small amounts or just a few drops, adopt the posture but
does not urinate, etc. This can occur in urine infections but also in
prostate problems or obstructions.
- Polyuria: increased urination frequency The dog will try to do
Pee many times and little amount.
- Hematuria: It is the presence of blood in the urine. This will be dark or with
clots or a few drops of blood at the end of urination. The urine will be more cloudy and
It will smell different.
In addition, dogs with kidney infection will have fever, anorexia, vomiting and
pain in the lower area of the loin, forcing them to walk hunched over and with their legs
How is it diagnosed?
If we observe that our dog shows some of the symptoms described we must
go to the vet first because there are several conditions that can cause
this symptomatology and, also, because a low urine infection that is not treated can
ascend to the kidneys.
Our veterinarian will ask us for a urine sample to analyze it and see if there is an infection or not. This data can be given to us by a urine test strip. A urine culture also indicates which bacteria are present and which is the most suitable antibiotic to eliminate them.
These tests usually detect bacteria, white blood cells and red blood cells. If we do not get a sample, which can happen especially in bitches, since it is more difficult to collect, the veterinarian can extract it directly from the bladder. Pyelonephritis or kidney infection can be seen on ultrasound as an enlarged kidney.
How is a urine infection created?
Actually there may be some predisposing factors. Dog age, diabetes, prolonged administration of corticosteroids or prostatitis, in the case of males, can influence the appearance of an infection.
In addition, it is important to know that stones can form around bacteria and
These are capable of obstructing the urinary tract. A complete obstruction constitutes
an emergency and is another reason to go to the emergency veterinarian.
What is the most effective treatment?
To avoid complications such as bacteria reaching the kidney, if our dog shows symptoms of a urinary infection, we should immediately go to the veterinarian to start treatment early.
This will consist of the administration of an oral antibiotic for 2-3 weeks or
even 6-8 if the infection affects the kidney. Although it is usual that in a short time the
treatment control the symptoms is essential that we provide until the end
To avoid relapses.
In addition, when the treatment is finished it is advisable to repeat the urine test, after a few days, to make sure that the infection is eradicated. If in a short time
the dog has another urine infection again, we should look for a possible cause
The veterinarian usually prescribes a broad-spectrum antibiotic, that is, active against numerous bacteria, based on a strip of urine that has tested positive for the infection.
Canine urinary tract infection
Urinary infections affect many dogs, especially females. Bacteria normally break into the urinary tract from the outside, and ascend through them to infect the urinary bladder and, sometimes, the kidneys themselves. Infectious agents, tumors, stones and improper feeding can influence their appearance and evolution.
The urinary tract They are part of the body system that removes water and many waste products. The excretory apparatus is composed of the kidneys, which filter and purify the blood. Excess water and waste chemicals circulate through the ureters, the ducts that connect the kidneys to the bladder, where urine is stored. When urinating, the bladder contracts to evacuate urine through a duct, the urethra, by which goes outside.
Also, in the case of the male dog, around the neck of the bladder is the prostate, a gland that produces and pours seminal secretions into the urethra.
Almost all urinary infections are caused by bacteria, being the most common Escherichia coli. These are common bacteria that are present in the environment and around the genitals and anal area of the dog. They constantly enter the urethra from the outside. Each time the dog urinates, these bacteria are dragged outward again. If the dog does not urinate often enough, bacteria can reach the bladder and cause an infection. In dogs, the prostate. Sometimes, the infection can then ascend through the ureters and affect the kidneys. The medical terms are cystitis, in the case of bladder infection, prostatitis in that of prostate infection, and nephritis in the one of the infection of the kidneys. All are different ways of urinary infection and can appear in isolation or at the same time.
Male dogs have a much longer urethra than females and usually urinate more frequently. For that reason, bacteria have less time to move through the urinary tract before being dragged by the stream of urine, so that they suffer Urinary infections much less frequently than females.
Bacteria can enter the urinary tract differently: through the bloodstream. The kidney is very active and constantly filters the blood, so it should not surprise us that it is one of the first organs to be affected by such infections. In these blood infections, many types of bacteria may be involved, which normally enter the bloodstream from periodontal tissues affected by a chronic infection or through an open wound. This form of nephritis It is characterized by permanent kidney damage due to a low-intensity but prolonged bacterial attack.
He urine pH of the dog (the degree of acidity or alkalinity of the urine) is influenced by feeding. A diet that alkalizes urine facilitates the onset of infections. Another factor is how often the dog urinates. Bacteria cannot be dragged outside unless the dog urinates frequently. This situation occurs, for example, when the dog remains too long locked up, or when it suffers from diseases that disable it to move properly, such as osteoarthritis (osteoarthritis) and, therefore, is reluctant to move.
Some diseases determine that the dog is more prone to suffer Urinary infections. Urinary tract obstructions caused by tumors or calculations (excrescences as stones, which are usually found in the urethra) are quite frequent. The hormonal changes They can cause an enlarged prostate. Bacteria that can specifically cause certain infectious diseases, such as Leptospirosis, They can also stay in the kidneys.
Signs may include:
- Increased frequency of urination (the animal urinates more frequently, is one of the first signs that the bladder is affected by a urinary infection).
- Discomfort when urinating (the dog urinates a small amount and repeatedly, even sometimes inside the home, and the males can bend down while doing so, instead of lifting the paw).
- Urine may appear stained with blood or cloudy.
- Urinary stones produce few symptoms in females. However, in males, urinary "stones" can clog the urethra, which is narrow, an infection of the prostate can also cause blockage of the urethra. In this situation the dog makes efforts to urinate without getting it and must be treated with extreme urgency.
- If the kidneys are affected, the animal will drink and urinate much more than normal, and may arch the back in pain. Blood-stained or cloudy urine may be more evident.
Diagnosis is normally possible from clinical symptoms, accompanied by a urine test with a test strip, which at the same time indicates the acidity and density of the urine and allows the presence of blood and proteins to be detected.
- The type of bacteria present and their sensitivity to the different antibiotics available.
- Kidney damage
- Obstruction due to tumors or stones.
- The increase in prostate size.
The treatment pursues the following objectives:
- Complete elimination of infectious bacteria from the bladder and kidneys.
- Elimination of bacteria that can access the urinary tract through the bloodstream (dental care, wound healing).
- Reset the correct urine pH (acidity / alkalinity balance).
- Ensure that the dog's routine allows him to urinate regularly.
- Elimination of possible causes of obstruction, such as stones or tumors.
It is often essential to administer a long course of antibiotics. Not finishing the entire course of antibiotics is one of the usual reasons for treatment failure.
The veterinarian will choose the most appropriate treatment in each case.
Allowing the dog to go out frequently to urinate is very important, as well as making sure that the animal has clean and renewed drinking water at all times.
It is essential to finish all antibiotic treatment because otherwise the infection may reappear.
The veterinarian may prescribe medications or a special diet to dogs that are prone to develop "stones" (stones) in the urinary tract. Some races are more prone to urinary stone formation. The veterinarian can recommend a special diet if your dog belongs to one of these breeds, as a prevention before the stones get formed.
Selecting a diet that provides an adequate pH to the dog's urine can be useful.
