Why Does My Dog’s Breath Smell Like Fish? Causes & Solutions

If you’ve noticed your dog’s breath smelling fishy, it’s not only unpleasant but could signify a health issue. Understanding the causes and addressing this problem is crucial to your dog’s comfort, preventing serious health issues, and improving your interactions with your pet.

This blog post will guide you through the causes and practical solutions for eliminating your dog’s fishy breath.

Common Causes of Fishy Breath in Dogs

Anal gland issues

Function of anal glands: Anal glands are small, scent-producing sacs located on either side of your dog’s anus. They naturally secrete a smelly, fishy substance during defecation or when your dog is scared or excited. This scent serves as a means of communication and territory marking among dogs.

Signs of anal gland problems: If your dog’s anal glands are not emptying properly or become infected, the fishy odor may become more noticeable. Some signs of anal gland issues include scooting, licking the rear area, or swelling near the anus.

How it affects breath: Dogs may lick their anal area when experiencing discomfort or irritation, transferring the fishy smell to their mouth and causing their breath to smell like fish.

Oral health problems

Plaque and tartar buildup: Plaque is a sticky film that forms on teeth and, if not removed, hardens into tartar. Both plaque and tartar can lead to bad breath, including a fishy odor, if left untreated.

Periodontal disease: Untreated plaque and tartar can lead to gum inflammation (gingivitis) and eventually periodontal disease. This condition results in the breakdown of gum tissue and supporting bone structure, often causing foul-smelling breath.

Tooth decay or infections: Damaged or decaying teeth can harbor bacteria, which produce unpleasant odors. Infections in the mouth, such as abscesses, may also contribute to a fishy smell in your dog’s breath.

Diet and food choices

Fish-based diets: Some dog foods are made with fish ingredients, which can result in a fishy smell in your dog’s breath. This is usually harmless and can be resolved by switching to a non-fish-based diet if the odor is bothersome.

Low-quality food and additives: Inexpensive dog foods may contain lower-quality ingredients and artificial additives that can contribute to bad breath. Feeding your dog a high-quality diet can help alleviate this issue.

Coprophagia (eating feces): Some dogs may eat their own feces or those of other animals. This habit not only leads to bad breath but can also introduce harmful bacteria into your dog’s mouth.

Gastrointestinal issues

Bacterial imbalances: An imbalance of bacteria in your dog’s gut can result in the production of foul-smelling gases, which may contribute to a fishy odor in their breath.

Gastroesophageal reflux: If your dog suffers from acid reflux or other gastrointestinal issues, stomach acid can travel up the esophagus and cause a fishy or sour smell in their breath.

Preventing and Eliminating Fishy Dog Breath

Regular grooming and dental care

Importance of brushing teeth: Just like humans, dogs need regular dental care to maintain good oral hygiene. Brushing your dog’s teeth at least a few times a week can help remove plaque and prevent tartar buildup, reducing the risk of bad breath and more serious dental issues.

Dental chews and toys: Dental chews and toys are designed to help clean your dog’s teeth as they chew. Providing these items can help reduce plaque and tartar while also keeping your dog entertained and promoting healthy chewing habits.

Professional dental cleanings: Schedule regular dental cleanings with your veterinarian to ensure your dog’s teeth and gums stay in top shape. This will not only help eliminate fishy breath but also prevent potential oral health issues from developing.

Proper nutrition

Choosing high-quality dog food: Opt for a high-quality, well-balanced dog food that contains easily digestible ingredients and avoids artificial additives. This can help minimize bad breath and support your dog’s overall health.

Avoiding fish-based diets if necessary: If your dog’s fishy breath is linked to their diet, consider switching to a non-fish-based food. Consult your veterinarian for recommendations that meet your dog’s specific nutritional needs.

Incorporating fresh fruits and vegetables: Adding dog-safe fruits and vegetables to your dog’s diet can help freshen their breath and provide additional nutrients. Examples include apples, carrots, and green beans.

Addressing anal gland problems

Regular vet check-ups: Schedule routine check-ups with your veterinarian to monitor your dog’s anal gland health. Your vet can detect and address any potential issues before they worsen, reducing the chance of fishy breath.

Expressing anal glands when needed: If your dog’s anal glands are not emptying properly, your vet may recommend expressing them manually. This can help alleviate discomfort and reduce the fishy odor associated with impacted or infected glands.

Maintaining a healthy weight: Obesity can contribute to anal gland issues in dogs. Ensuring your dog maintains a healthy weight through proper diet and exercise can help prevent these problems and the associated fishy breath.

Monitoring gastrointestinal health

Probiotic supplements: Probiotics can help balance the bacteria in your dog’s gut, potentially reducing fishy breath caused by bacterial imbalances. Consult your veterinarian for guidance on choosing a suitable probiotic for your dog.

Regular vet visits for checkups: Keep up with your dog’s regular veterinary check-ups to monitor their gastrointestinal health. Your vet can detect and address any potential issues early on, helping to maintain your dog’s overall well-being and minimize the chance of fishy breath.

When to Seek Professional Help

Symptoms of serious oral health issues

While some level of bad breath is normal in dogs, it’s crucial to recognize when the issue may be indicative of more significant health problems. If your dog’s fishy breath is accompanied by symptoms such as swollen, red, or bleeding gums, loose teeth, or difficulty eating, it’s time to consult your veterinarian.

These signs could indicate severe dental issues that require professional attention.

Signs of chronic anal gland problems

If your dog is persistently scooting, licking their rear area, or showing signs of discomfort around their anus, it may indicate chronic anal gland issues. In these cases, it’s essential to seek veterinary care to diagnose and address the problem, which could include infection or impaction.

Ignoring these issues can result in worsening symptoms and further complications.

Persistent fishy breath despite intervention

If you’ve tried the preventative and care measures outlined above and your dog’s fishy breath persists, it’s essential to consult your veterinarian. Persistent bad breath could signal an underlying health issue that requires professional diagnosis and treatment.

By seeking help, you can ensure your dog’s well-being and keep their breath smelling fresh and clean.
