Sometimes dog owners notice that their pet has a strange fishy smell. This can be either a temporary occurrence or a sign of a more serious issue. There’s even a name for it. It’s important to identify the source of the smell and take action to ensure the dog’s comfort and health.
Why does my dog smell like fish?
A fishy odor in dogs can appear for various reasons. Most commonly, it is caused by either natural factors or medical issues that require attention.
Natural causes can sometimes lead to this smell, and they are usually harmless. If a dog’s diet includes fish-based food, Omega-3 fatty acids, or seafood supplements, these can affect the scent of its saliva, fur, and even skin. Some breeds, such as Retrievers or Spaniels, have a specific skin secretion that may emit a faint fishy odor, especially if their fur remains damp for an extended period after bathing.
However, a fishy smell often indicates medical issues. One of the most common reasons is dental problems. If tartar builds up in the mouth, gum infections develop, or periodontal disease sets in, the unpleasant odor can become quite strong. Similarly, fungal or bacterial ear infections can create a fishy smell, particularly in dogs with floppy ears, where warmth and moisture promote bacterial growth.
The most common cause of a fishy odor is the anal glands. These small glands, located near the anus, produce a specific secretion that dogs typically release on their own. However, if the glands become inflamed or clogged, the secretion starts to emit a strong, fish-like smell. Many dogs experiencing this issue will excessively lick under their tail or rub their rear against the floor.
How to Identify the Source of the Smell?
To accurately determine where the fishy odor is coming from, it’s important to carefully inspect your dog and check key areas where problems might occur.
First, examine the mouth. Open your dog’s mouth and look at the condition of the teeth and gums. Plaque, tartar buildup, redness, or even bleeding are signs of dental issues. If the smell originates from the mouth, the dog might have gingivitis or periodontal disease, which require proper care and teeth cleaning.
The next step is checking the coat and skin. Fungal infections or skin irritations can cause a distinctive smell. Pay special attention to areas under the paws, behind the ears, and in skin folds (such as in bulldogs, pugs, and other wrinkly breeds). If the fur appears greasy or has crusty patches, consulting a veterinarian is recommended, as these could be dermatological issues.
If the source of the odor isn’t in the mouth or coat, inspect the area under the tail. If the anal glands are full or inflamed, they can emit a strong fishy smell. You may also notice swelling or redness. If the dog frequently licks this area or scoots its rear along the floor, it’s a clear sign that the problem lies there.
Identifying the source of the smell will help resolve the issue faster and restore your pet’s comfort and freshness. If you’re unable to determine the cause on your own, visiting a veterinarian is the best way to prevent complications.
How to Get Rid of the Fishy Smell?
If you notice that your dog smells like fish, the key is not to ignore the issue. Depending on the cause, the solution may be simple or require a more comprehensive approach. In any case, regular care will not only eliminate the odor but also prevent it from recurring.
If the problem is related to the mouth, regular tooth brushing can significantly improve the situation. Just like humans, dogs need dental care since plaque and bacteria cause bad breath. Use a special dog-friendly toothpaste (human toothpaste is not suitable) along with a toothbrush or a rubber finger brush. If your dog dislikes brushing, you can try dental treats that help reduce tartar buildup. Some owners also opt for sprays or water additives that help maintain fresh breath.
If the odor originates from the coat or skin, regular grooming visits are essential. Professional bathing and coat cleaning help remove greasy buildup, bacteria, or fungi that may contribute to the unpleasant smell. However, the most crucial procedure is anal gland expression. Some dogs cannot empty their anal glands on their own, requiring assistance from a professional. A groomer or veterinarian can perform this procedure quickly and painlessly, eliminating the fishy odor and discomfort.
Another important factor is diet changes. If your dog consumes food with fish-based ingredients, fish oil, or seafood, it may affect its natural scent. Try switching to chicken, turkey, or beef-based food and observe any changes. Additionally, ensure a balanced diet, as vitamin deficiencies or digestive issues can contribute to body odor.
When Should You See a Veterinarian?
Sometimes, an unpleasant odor is more than just a cosmetic issue—it can be a sign of an underlying health problem. It’s important not to delay a visit to the vet if the smell becomes very strong, worsens, or is accompanied by other symptoms. If the fishy odor persists even after anal gland expression or dental care, it could indicate an internal health issue that requires further examination.
If your dog licks excessively under the tail, scoots its rear on the floor, or acts restless, this is almost always a sign of anal gland problems. Inflamed glands can cause pain, and in severe cases, abscesses may form. In such situations, a veterinarian can manually express the glands and, if necessary, prescribe anti-inflammatory medication or antibiotics.
Additionally, be on alert if your dog shows redness, rashes, or excessive itching. This could indicate an allergic reaction, bacterial or fungal infection, or even internal organ dysfunction, such as liver or kidney problems. In such cases, the vet will likely recommend tests to determine the exact cause.
A fishy smell in dogs is not normal, but in most cases, it can be resolved with proper care. The key is not to ignore the issue and take timely action to keep your pet comfortable and healthy.
