Tendency to Infections (Skin, Urinary Tract) in Dogs
The tendency to infections in dogs describes the frequent occurrence of infections, especially of the skin and urinary tract, which may indicate a weakened immune system or other underlying health problems.
Can Occur with the Following Diseases:
Basics and possible causes
In dogs, an increased tendency to infections can have various causes. A weak immune system is one of the most common reasons. A dog’s immune system plays a crucial role in defending against pathogens such as bacteria, viruses, and fungi. If the immune system is weakened, it cannot effectively fight these invaders, leading to frequent infections.
Skin infections can be caused by allergies, parasites such as fleas and mites, or by injuries and wounds that allow bacteria to enter the skin. Allergies are particularly common and can be triggered by food, environmental factors, or flea bites. These allergic reactions often lead to itching, scratching, and secondary bacterial infections.
Urinary tract infections (UTIs) often occur when bacteria, usually from the gut, enter the urethra and bladder. Female dogs are more susceptible to UTIs due to their anatomical structure, as their urethra is shorter and closer to the anus, which facilitates the entry of bacteria. Factors such as inadequate water supply, urinary retention, or anatomical abnormalities can also increase the risk.
Other possible causes for recurrent infections can be hormonal imbalances, such as in Cushing’s syndrome or hypothyroidism. Both conditions affect the immune system and can increase the dog’s susceptibility to infections. In addition, genetic factors or certain breed predispositions may play a role, as some dog breeds are prone to specific health problems.
Typical accompanying symptoms
-
Itching and skin redness: Frequent scratching, biting, or licking of the skin can be signs of skin infections or allergies. These symptoms often lead to redness and can lead to open wounds or hair loss.
-
Frequent urination or uncleanliness: A dog with a urinary tract infection may need to urinate more often than usual, have difficulty holding urine, or even be unclean in the house.
-
Painful or difficult urination: Dogs with HWIs sometimes show signs of pain or discomfort when urinating. They may whimper when urinating or squat frequently to urinate without passing much urine.
-
Foul-smelling urine or discharge: A strong-smelling urine or an unusual discharge may indicate an infection. In the case of skin infections, a foul odor may emanate from the skin or ears.
-
General malaise: Lethargy, loss of appetite, or depressive behavior may indicate a systemic infection or the dog’s general malaise caused by persistent discomfort.
When to visit the vet?
A veterinarian should be consulted if the symptoms are severe or worsen. If a dog shows signs of pain when urinating or there is blood in the urine, an immediate visit to the veterinarian is necessary. These symptoms may indicate serious problems such as bladder stones (uroliths) or a kidney infection.
A veterinarian should also be consulted if skin infections recur or spread despite treatment. Chronic infections may indicate a deeper underlying problem that requires specific therapeutic measures.
If the dog shows signs of systemic diseases, such as persistent lethargy or loss of appetite, a veterinary examination is advisable to rule out possible underlying diseases that can lead to recurrent infections.
Symptom recognition for animal owners and veterinary diagnostic procedures
Pet owners can recognize symptoms such as frequent scratching, changes in urination, or unusual odors. These observations are valuable when communicated to the veterinarian, as they can help with the diagnosis.
The veterinarian will perform a comprehensive physical examination of the dog to identify signs of infection. If a skin infection is suspected, the veterinarian may take skin swabs, scrapings, or biopsies to determine the cause. In the case of HWIs, urine samples can be taken for microbiological analysis to identify infectious agents.
Blood tests can be performed to assess the dog’s general health and to test for systemic diseases such as Cushing’s syndrome or thyroid problems. Ultrasound or X-ray examinations may be necessary to rule out anatomical problems in the urinary tract.
What can pet owners do and professional therapy options
As a first measure, the pet owner should ensure that the dog has enough fresh water available to flush the urinary tract and avoid dehydration. A balanced diet that meets the dog’s specific needs can strengthen the immune system and reduce the risk of infections.
For skin infections or allergies, regular bathing with a medicated shampoo recommended by the veterinarian can help remove bacteria and allergens from the skin. Avoiding allergens, whether through a special diet or adjustments in the environment, can also be helpful.
It is important to administer any medications prescribed by the veterinarian, such as antibiotics or antihistamines, exactly as directed to effectively combat infections and prevent relapses. The pet owner should also make sure that the dog does not scratch or lick affected areas, as this can worsen infections.
Outlook on current research
The tendency to infections, especially of the skin and urinary tract, in dogs is a growing interest in veterinary medical research. A central focus is on investigating the genetic predispositions that could make certain breeds more susceptible to such infections. Scientists use genomic analyses to identify genetic markers associated with an increased risk of infection. In the long term, this research could help develop targeted breeding programs to reduce susceptibility to infections.
Another significant area of research is the microbiome of the skin and urinary tract. New studies show that the balance of microorganisms on the skin and in the urinary tract plays a crucial role in defending against pathogens. Researchers are investigating how probiotics and prebiotics can support the microbiome to strengthen the dogs’ immune system and reduce the frequency of infections. These approaches could lead to innovative treatment methods that rely less on antibiotics.
In addition, intensive research is being conducted on the development of new diagnostic tools. Rapid tests and imaging techniques are intended to enable early detection and differentiation of infections in order to initiate targeted treatments. Advances in imaging technology, such as improved ultrasound and MRI technology, could enable faster and more accurate diagnosis of the underlying causes of infections.
Another focus is on investigating the role of the immune system in susceptibility to infections. Research focuses on how immune disorders or weaknesses contribute to the tendency to infection. New approaches in immunotherapy could potentially be used to specifically strengthen the immune system and prevent infections. In addition, vaccines against common pathogens of skin and urinary tract infections are being developed to improve prevention.
Finally, the role of nutrition in the prevention of infections is also being investigated. Certain nutrients and diets that support the immune system could play a key role in reducing the tendency to infection. Researchers are investigating the effect of omega-3 fatty acids, antioxidants, and special dietary supplements on strengthening the immune defense in dogs.
