Key Takeaway
A fishy odour from your dog’s breath often points to dental issues like plaque and tartar buildup, or infections in the mouth. Addressing these promptly can prevent more serious health complications and keep your furry friend’s smile healthy.
Understanding the Unpleasant Odour: Why Your Dog’s Breath Smells Fishy
As pet parents, we adore our canine companions, from the playful antics of a Labrador to the independent spirit of an Indian Pariah dog. But there’s one aspect of their care that can be, quite frankly, offensive: bad breath. While occasional “dog breath” is normal, a persistent, strong fishy smell is a red flag that needs your attention. As a veterinarian, I often hear this concern, and it’s crucial to understand the potential causes and how to manage them effectively.
Common Culprits Behind a Fishy Doggie Smile
That distinct fishy odour is rarely a random occurrence. It’s usually a sign that something is amiss, primarily within your dog’s oral cavity. Let’s dive into the most frequent reasons:
1. Dental Disease: The Leading Suspect
This is by far the most common cause of a fishy smell. When plaque and tartar build up on your dog’s teeth, they create a breeding ground for bacteria. These bacteria produce volatile sulphur compounds, which are notoriously pungent and often described as fishy or rotten. If left untreated, this can escalate into:
- Gingivitis: Inflammation of the gums, making them red, swollen, and prone to bleeding.
- Periodontal Disease: A more severe infection that affects the structures supporting the teeth, potentially leading to tooth loss and bone damage.
2. Anal Gland Issues: An Unexpected Connection
While it might seem strange, your dog’s anal glands can also contribute to a fishy odour, though it’s usually a more general “skunky” or “fishy” smell emanating from their rear end rather than their mouth. These small sacs located on either side of your dog’s anus secrete a fluid used for scent marking. If these glands become impacted or infected, they can leak, and the strong smell can sometimes be detected on your dog’s breath if they lick the area.
3. Diet: What Goes In, Comes Out
Certain dog foods, especially those with high levels of fish oil or fish meal, can sometimes contribute to a fishy odour in your dog’s breath. While these ingredients are often beneficial for skin and coat health, in some cases, they can be a contributing factor to breath odour. Similarly, if your dog has ingested something unusual, like spoiled food or even a dead creature, this can temporarily cause an unpleasant smell.
4. Underlying Health Conditions
Less commonly, a persistent bad breath, including a fishy smell, can be an indicator of more serious health issues such as kidney disease, diabetes, or gastrointestinal problems. These conditions can alter your dog’s metabolism and lead to the production of specific odours in their breath.
When to Seek Veterinary Advice
If you notice a sudden or persistent fishy odour from your dog’s breath, it’s always best to consult your veterinarian. They can perform a thorough oral examination to check for dental disease, examine the anal glands, and rule out any other underlying health concerns. Early detection and intervention are key to maintaining your dog’s overall health and well-being.
Prevention and Management: Keeping That Fishy Smell at Bay
Fortunately, there are proactive steps you can take to combat and prevent that fishy breath:
1. Regular Dental Care is Non-Negotiable
This is your first line of defence. Aim for daily teeth brushing using a dog-specific toothpaste and toothbrush. If daily brushing isn’t feasible, aim for at least a few times a week. For those hard-to-reach spots and to help break down plaque, consider using dental chews or toys designed to scrape away build-up. The Liyo Buddy toy, with its unique textured surface, is excellent for this purpose. When your dog chews on it, it can help mechanically clean their teeth and gums, much like brushing, and is far more enjoyable for them!
2. Professional Dental Cleanings
Just like humans, dogs benefit from professional dental cleanings performed by your vet. These cleanings go beyond what you can do at home, allowing for thorough scaling and polishing, and addressing any deeper issues below the gum line.
3. Diet Review
Discuss your dog’s diet with your vet. If fish-based foods are a concern, they might recommend an alternative. Ensuring a balanced and appropriate diet is crucial for overall health, including oral hygiene.
4. Anal Gland Expression
If anal gland issues are suspected, your vet can manually express them during a visit. Regular expression might be recommended for dogs prone to this problem.
