Why Does My Dog Smell Like Fish?

If your dog is smelling like fish, it is likely caused by anal sac fluid. This fluid can release onto the tongue and mouth. This fluid has a strong fishy smell and may be difficult to distinguish from regular dog breath. There are many causes of this problem.

Anal sac disease

A dog with an anal sac disease may be experiencing an unpleasant fishy odor. The smell is caused by an impacted anal sac, which requires antibiotic treatment. In some cases, there may also be a tumor in the area. In either case, the dog needs to see a vet to determine the severity of the problem and the best course of treatment.

Anal sac problems are relatively easy to treat. Once the underlying problem is solved, the fishy smell should go away. The most common cause is simple impaction. However, other issues with the anal sac include an abscess, an infection, and even cancer. If your dog is constantly licking its bottom, scooting, and having difficulty using the bathroom, it may be due to anal sac disease.

Anal sac disease is not a common problem for large breed dogs. However, it is common in small breeds and overweight dogs. Using a dog-safe wipe can help keep the anal area clean. In addition to regular bathing, proper hygiene is important. Additionally, a deodorant formulated for dogs can help your pet stay fresh.

If you suspect your dog has an anal sac disease, visit your veterinarian. If you notice that your dog is scooting on the floor, biting its anus, or licking its anus, your veterinarian can perform a test and confirm the diagnosis. A veterinarian can also perform surgery if necessary. Anal sac disease is painful and can lead to severe emotional and physical damage if not treated.


Fishy breath in dogs can be an indication of a urinary tract infection or other health problem. The foul smell may be caused by a buildup of bacteria and yeast. A vet can recommend antibiotics to treat this infection. The discharge from your dog’s anal glands may also smell like fish. If your pet is leaking fluid from its anal glands, it could be a sign of a urinary tract infection or pyometra, which is a potentially life-threatening infection.

In some cases, fishy breath in dogs can be caused by many different issues, including dental problems, digestive problems, kidney disease, and diabetes. To determine the exact cause of your dog’s fishy breath, you’ll need to perform a full physical examination. If your dog has teeth that are inflamed or have tartar, they may be suffering from periodontal disease, which is the main cause of fishy breath in dogs.

Changing your dog’s diet to one that contains a higher percentage of omega-3 fatty acids may help eliminate the fishy smell in your dog. Omega-3 fatty acids improve skin and coat health, which in turn helps to reduce body odor in your pet. Regular baths also help remove buildup of bacteria. Choose a dog shampoo that is gentle. Avoid using human shampoo on your dog as it may be too harsh for its sensitive skin.

Another cause of fishy breath in dogs is a buildup of bacteria in the mouth. It’s important to brush your dog’s teeth regularly and use dental chews to help your dog maintain their teeth. Regular dental cleanings may also be necessary if your dog has fishy breath.


If your dog has started to smell like fish, you should investigate what may be causing the problem. Fishy smells in dogs can be a sign of a variety of diseases or infections. It could also be the result of a fishy snack or a fish oil supplement your dog is taking. If the smell continues, however, you should seek the help of a veterinarian. The most common cause is an overgrowth of foul-smelling bacteria in the anal gland.

Another cause of fishy breath in dogs is a blocked anal sac. The fluid from this sac can leak onto the dog’s mouth and tongue. If the problem continues, your dog could have an underlying health problem that needs to be treated. A veterinarian can help you determine whether your dog is suffering from a digestive issue or is just suffering from fishy breath.

Allergies can also cause a fishy smell in dogs. The irritation from an allergic reaction can cause the dog to lick itself excessively, causing a buildup of bacteria that contributes to the unpleasant odor. A good way to deal with allergies in your dog is to bathe them regularly with a dog-safe shampoo. Using a deodorizing wipe or spray in between baths can also help. For severe cases of allergies, you should seek the advice of a veterinarian who can prescribe a treatment plan.

Changing your dog’s food may help. However, switching foods should be done gradually, reducing the old food and gradually increasing the new food. Your veterinarian can also prescribe a better food or supplement to help your dog digest the new food.

Periodontal disease

If you’ve ever noticed your dog’s breath is smelling like fish, it could be an early sign of periodontal disease. The smell comes from bacteria that have invaded the gums. While the smell is unpleasant, it’s not always life-threatening. In some cases, it’s simply a result of poor dental hygiene or a bacterial infection. Fortunately, there are some things you can do to help your dog’s breath smell better.

The first step in treating periodontal disease in dogs is to remove the source of the problem. This involves a thorough dental cleaning. Under general anesthesia, your veterinarian will remove plaque and tartar from your dog’s teeth. During this procedure, he will also check the periodontal support in each tooth. X-rays of the gums will also be taken to determine whether the condition is advanced. In more severe cases, the veterinarian may need to remove your dog’s teeth.

Periodontal disease in dogs can be a warning sign of a more serious dental condition. If untreated, this bacterial infection can lead to tooth loss, gum bleeding, and tooth damage. In some cases, it can even lead to abscesses and infection. For this reason, it’s important to schedule regular checkups with your veterinarian and schedule dental cleanings for your dog.

Dogs with periodontal disease may have a fishy odor. Regular brushing will help prevent bacterial infections from affecting your dog’s mouth. Your veterinarian will also check for signs of dental disease, including chewing problems and bad breath.

Infected anal glands

If you notice that your dog has a fishy smell coming from his anal glands, it is important to see a vet for further investigation. The smell can be caused by an infected anal sac, which may need to be flushed or removed. In some cases, a dog may release his anal glands accidentally when it is scared. However, there are many other causes of a fishy smell.

Your dog may have a fishy smell if he’s been in the pool or rolled around in smelly things, such as dead fish. This smell is often caused by impacted anal glands, which prevent proper drainage. This blockage allows stinky gas to build up in the rectum, which causes the dog’s fur to smell fishy.

Infected anal sacs are the most common type of anal problem in dogs, affecting 4% of dogs each year. These infections are painful and can cause the distinctive fishy smell that most dog owners associate with fish. Fortunately, there are several simple treatments that can alleviate the symptoms and restore your dog to a normal state of health.

An impacted anal sac can be painful for your dog and can cause a fishy odor. You should take your dog to a vet to have the problem treated. A veterinarian can squeeze the anal sac manually, and may also prescribe antibiotics. If the fluid buildup is not addressed, the gland may rupture and lead to an infection or an abscess. In addition to the fishy smell, your dog may also experience bleeding.

Infected anal glands are the main cause of a fishy odor in dogs, and can be a symptom of a more serious condition. While anal glands are responsible for a fishy smell, other causes of a fishy odor include dental problems, dental disease, and an infection in the mouth. A vet should be consulted if you notice a fishy odor in your dog.
