4 Reasons Why Your Dog Smells Like Fish

We’ve covered 4 of the most probable reasons your dog smells like fish. And we’ve also provided the best solution for your benefit.  

Let’s not wait anymore and dig into it!

Reason 1: Anal Glands

Anal gland emissions often have a fishy stench since these contain a collection of sebaceous glands. These can end up causing unpleasant odors. Also, the anal sacs work as a smell identifier when your dog takes a dump.

The Anal Sac Disease is pretty prevalent in dogs, with exceptionally tiny varieties. It is induced by the anal sacs getting affected or blocked due to duct irritation. This causes inflammation and pain for your dog. 


It’s vital to see a veterinarian or groomer if your dog’s rectal glands are infected. Specialists will stimulate the glands to help them discharge their substances.

If your dog experiences rectal impaction regularly, you should learn to treat its anal sacs. Ask your veterinarian to teach you how to do everything correctly. 

It’s pretty straightforward. If you keep doing it yourself, you can conserve money on visits to the vet. 

Your veterinarian can determine if the tumor is the source of the problem. In that case, your dog may require medication, surgery, or radiation treatment to be treated. This form of treatment will vary based on the kind of illness.

Reason 2: Dental Issues

Dogs are prone to dental problems. It’s widespread if the owner doesn’t have their pets’ teeth checked regularly. 

Many dogs have a terrible breath as a result of this. If you notice your dog sleeping with its tongue out, then know dental issues cause it.

Periodontitis stinks your dog’s mouth and might lead to significant difficulties. Dental treatment and proper hygiene are essential for our canine companions.

N.B. Both kidney illness and type 2 diabetes can generate a peculiar or unpleasant smell. 


If your dog gets fishy breath frequently, seek guidance from your veterinarian. Cleaning its teeth on a routine basis won’t be sufficient in the case of gum disease. They will also need to be addressed by your veterinarian.

Reason 3: Yeast Infection

If there is an overflow or infestation of yeast, it emits a rather fishy odor. It is more common in dogs having extra skin, such as Bulldogs. 

Their skin creases can accumulate yeast and dead cells. This results in a stinky, fishy stench. 

If your dog licks other dogs, there’s a chance of disease transmission. Pathogens can also form within your dog’s ears and nose. They are also likely to develop all around the eyes and between the tips of their toes.

Many dogs suffer from ear ailments caused by excessive yeast and bacteria. If your female dog smells musty, she could suffer from yeast or microbial illness. Examine for any evidence of white and yellow secretion as a further disease symptom.


Carbs must be kept to a minimum in your dog’s total calorie intake. This can be advantageous. However, a bath with hot water and specific dog shampoos is the best treatment.

Reason 4: Urinary Tract Infection (UTI)

If your dog’s pee smells fishy, it may have a urinary tract infection (UTI). This illness inside the urinary tract can create an overgrowth of bacteria. It would help if you took your dog to the clinic because this results in a foul odor.

UTIs cause dogs to pee repeatedly since they have difficulties maintaining it. This can produce pain and distress while urinating. Thus your dog may howl in pain when peeing in severe cases of UTIs. There could also be bleeding in the urine.


If you discover that your dog’s urine stinks unusually strong, take her to the clinic. Your vet will carefully investigate your companion. They would then perform a urinalysis and maybe a blood culture.

If an issue is found, medications will be sanctioned to treat it. You’ll need to get medical attention when it becomes a recurring issue. 

Then your dog may need to have X-rays and ultrasounds performed. This will be done so to aid in the diagnosis of the ailment.

Terrible quality pet food is a common cause of UTIs. In addition, your veterinarians may advise you to adjust your dog’s nutritional intake. This will most typically be a simple switch from dry to wet kibble.

As a result, your veterinarian will suggest a diet specifically formulated to address the illness. Specialists will recommend food that contains the nutrients required to enhance your dog’s immune system. Your dogs can eat spinach and other foods to combat UTIs.

Here are four common reasons for the problem, and we tried to give a solution for every reason. Try to work accordingly.


How can you tell if your pet’s testicles are swollen?

If your pet’s testicles are overburdened, they may emit a foul, pungent odor. Patches of the reddish substance may appear wherever your dog has sat. In this case, your dog will constantly scratch his rear.

How frequently should I clean my dog?

Whilst regularity of bathing varies from dog to dog. Petco says a decent rule of thumb is to clean your dog once every four weeks. This will assist in maintaining their skin texture fresh. 

Why do dogs wipe their mouths on the floor after they’ve been bathed?

It is usual for dogs to cover their aroma with mud, corpses, and dung. If your dog moves around and bumps into everything, it’s trying to reclaim its odors.
