Potential Causes of Ammonia Smell in Dogs

Urine Concentration

One potential cause of ammonia smell in dogs is urine concentration. When a dog’s urine is highly concentrated, it can have a strong ammonia odor. This can happen if the dog is not drinking enough water or if they have certain underlying health conditions.

UTI or Bladder Infection

A urinary tract infection (UTI) or bladder infection can also be a cause of ammonia smell in dogs. These infections can lead to an accumulation of bacteria in the urinary tract, which can result in a foul-smelling urine.

Kidney Disease

Kidney disease is another possible cause of ammonia smell in dogs. When the kidneys are not functioning properly, toxins build up in the body, leading to a distinctive odor. Ammonia smell can be a sign that the dog’s kidneys are not filtering waste products effectively.

Liver Disease

Liver disease can also contribute to the presence of ammonia smell in dogs. When the liver is not functioning properly, toxins can accumulate in the bloodstream. One of these toxins is ammonia, which can be detected through the dog’s breath and body odor.


Diabetes can impact a dog’s metabolism, affecting how the body processes waste products. This can lead to an excess build-up of ammonia in the body, resulting in an ammonia smell.


Dehydration can cause the urine to become more concentrated, leading to an ammonia-like smell. When a dog is not consuming enough water or is experiencing excessive fluid loss, dehydration can occur, and it can contribute to the presence of an ammonia odor.

Diet and Nutrition

The dog’s diet and nutrition can also impact their body odor. Certain food ingredients, especially those containing high protein content, can result in an ammonia-like smell in the dog’s urine and body odor. It is important to ensure that the dog is receiving a balanced and appropriate diet.


Various infections, such as skin infections or ear infections, can produce a distinct smell in dogs. In some cases, these infections may also contribute to an ammonia-like odor.

Metabolic Disorders

Certain metabolic disorders or imbalances can cause changes in a dog’s body odor. These disorders can affect how the body processes substances, leading to the presence of ammonia smell.

Breath Odor

Bad breath, or halitosis, is another symptom that can be associated with an ammonia smell in dogs. Dental issues, such as gum disease or tooth decay, can result in bacterial growth in the mouth, leading to foul-smelling breath that may resemble ammonia.

Signs and Symptoms of Ammonia Smell in Dogs

Strong Odor from Dog’s Body

One of the primary signs of ammonia smell in dogs is a strong, distinct odor emanating from their body. This smell is often unpleasant and may resemble the scent of ammonia or urine.

Increased Thirst and Urination

Dogs experiencing an ammonia smell may exhibit increased thirst and urination. The body’s attempt to eliminate waste products can lead to more frequent urination, which may have a stronger ammonia odor than usual.

Changes in Appetite

A dog with an ammonia smell may also exhibit changes in appetite. They may eat less or become uninterested in food due to underlying health issues causing the odor.

Lethargy and Weakness

Lethargy and weakness can be signs that there is an underlying issue contributing to the ammonia smell in dogs. These symptoms may indicate a more serious condition that requires veterinary attention.

Vomiting and Diarrhea

In some cases, dogs with an ammonia smell may experience vomiting or diarrhea. These gastrointestinal symptoms can be indicative of various health problems that need to be addressed by a veterinarian.

Yellowing of Eyes and Gums

Yellowing of the eyes and gums, known as jaundice, can be a sign of liver disease or other conditions that may contribute to the presence of an ammonia smell. If a dog displays this symptom, it is crucial to seek veterinary care.
