Ever wondered, “Why does my pet have a fishy scent?” You’re in good company. It’s a frequent query among pet parents and, while it can be worrisome, the cause is often straightforward and entirely treatable.
From issues with anal glands to dental concerns, multiple reasons could cause your pet to have fishy odours. Thankfully, most of these can be addressed or managed with the correct care, hygiene, and nutrition. In many cases, it’s not a reason to panic—but it is a reason to pay close attention.
Prior to jumping to conclusions, here’s what you need to grasp about that distinct fishy smell—and how to assist your pet in smelling (and feeling) fresher again.
Could It Be a Digestive or Glandular Problem?
One of the leading reasons pets develop a fishy scent is related to their anal glands—two small scent glands located beside the anus. These glands emit a strong-smelling fluid typically released during stool passing.
However, if these glands are blocked, overfilled, or infected, the smell can become intense—and quite fishy. It might persist on your pet’s coat or bedding, and you might also observe your pet scooting, licking their rear, or displaying signs of discomfort.
In such instances, diet and digestion are crucial. That’s why many pet owners turn to high-quality pet supplements to support digestive health and firm up stools—ensuring the glands express naturally during bowel movements. Ingredients such as fibre, probiotics, and anti-inflammatory compounds can play a significant role in enhancing gut function and minimising gland issues.
In some pets, recurring gland problems can signal a deeper dietary imbalance or intolerance. It’s worth reviewing not only their fibre intake but the overall digestibility of their food.
Additional Common Causes of Fishy Pet Odour
While anal glands are the primary suspect, they aren’t the sole explanation. Here are a few other frequent causes:
Dental Issues
Unpleasant breath is one thing—but if your pet’s breath has a fishy odour, it might indicate dental decay or infection. Plaque and bacteria accumulation can result in a foul-smelling mouth, especially in smaller breeds more susceptible to dental problems.
What to look for: Tartar on the teeth, red or swollen gums, difficulty chewing, or pawing at the mouth.
Ear Infections
If the fishy smell emanates from your pet’s head or ears, an ear infection might be the cause. Yeast and bacteria thrive in warm, moist environments—particularly in floppy-eared breeds—and can produce a strong, fishy odour.
What to look for: Head shaking, scratching, redness, or discharge from the ear canal.
Skin Conditions
Yeast infections, hotspots, or sebaceous gland issues on your pet’s skin can create unusual smells. Pets with allergies or sensitive skin might be particularly prone to these types of flare-ups.
What to look for: Greasy or flaky skin, hair loss, persistent scratching, or red patches.
Diet
Occasionally, the smell originates from inside out. Certain low-quality diets, food intolerances, or even fish-based pet foods can contribute to stronger-smelling breath, skin, or stool.
Switching to a more balanced, plant-based or limited-ingredient diet might aid in neutralising odours over time. Also, consider the role of hydration—sufficient water intake supports every metabolic function, including the skin and coat.
How to Address It
The initial step in resolving a fishy smell is identifying its source. A quick smell test (unpleasant but essential!) can help determine if it’s your pet’s rear, mouth, ears, or general body odour.
Once you have an idea of the source, you can take these steps:
Examine and Express Anal Glands (if needed)
If anal glands are the issue, request your vet or groomer to express them manually. In some cases, especially if there’s infection or chronic problems, your vet might recommend regular maintenance or even minor surgery.
Enhance Digestive Health
Support your pet’s gut with the right balance of fibre, prebiotics, and anti-inflammatory nutrients. This can help reduce soft stools and foster healthy gland function. Nutritional pet supplements designed for digestion and immune health offer an easy way to provide extra support.
Oral Hygiene
Brush your pet’s teeth regularly (daily if feasible) and consider dental chews or water additives. If there’s existing dental disease, a professional cleaning under anaesthesia might be necessary. Regular dental care can not only improve smell but boost your pet’s overall wellness.
Address Ear or Skin Infections
If you suspect an ear or skin issue, don’t delay. These infections can deteriorate swiftly. Your vet can prescribe antifungal or antibiotic treatments, based on the cause.
Reassess Their Diet
Evaluate what your pet is consuming. Contemplate transitioning to a cleaner, vet-formulated meal—ideally one crafted to support skin, coat, and digestive health. For pets with sensitivities, avoiding overly processed or animal-byproduct-heavy foods can be profoundly impactful.
When to Consult a Vet
Sometimes a fishy smell is merely a temporary issue—particularly if your pet rolled in something questionable. However, in many cases, it’s an indicator of something that demands attention. You should consult your vet if:
- The smell persists despite bathing or grooming.
- Your pet shows signs of discomfort (scooting, licking, pawing at ears/mouth).
- There is swelling, redness, or discharge from any part of the body.
- Your pet is eating less, seems lethargic, or behaves out of character.
Early diagnosis can avert complications and expedite treatment.
Promoting Odour-Free Wellbeing, Naturally
Ultimately, many causes behind that fishy smell boil down to internal imbalances—digestive trouble, inflammation, or poor hygiene. Luckily, holistic, proactive measures are within reach.
Brands such as Omni Pet have developed plant-based, science-backed solutions that support every facet of your pet’s health—from digestion and immune support to clean, hypoallergenic meals. In conjunction with regular hygiene practices, proper nutrition can help eradicate the source of unpleasant smells at the root.
Final Reflections
A pet with a fishy odour may seem like a minor issue, but it often indicates something that warrants attention—whether it’s a blocked gland, a dental problem, or an impending infection. The positive news? With the correct approach, it’s almost always manageable.
So next time your pet smells less than fresh, remain calm. Investigate, support their system with quality food and supplements, and seek professional guidance if necessary. The outcome? A healthier, happier (and significantly better-smelling) companion.
