Quick Comparison

Quick answer

Our top pick is Purina Pro Plan Adult Shredded Blend Chicken & Rice Formula. It combines high protein with crunchy kibble that helps reduce plaque and tartar, tackling bad breath at its source.

What to consider for High Protein Dog Food For Dogs With Bad Breath

Bad breath in dogs is often caused by oral bacteria breaking down food particles and producing sulfur compounds. A high protein diet can exacerbate bad breath if protein sources are low quality or if the food lacks dental benefits. Look for kibble with a texture that mechanically cleans teeth, such as larger, crunchy pieces. Also consider added ingredients like chlorophyll or parsley that may freshen breath. Always consult your veterinarian to rule out underlying dental disease.

What to look for in a dog food

Choose a food that is AAFCO complete and balanced for your dog’s life stage. The first ingredient should be a named meat, like chicken or salmon. Protein content should be between 25% and 35% on a dry matter basis, fat between 12% and 20%, and calories around 350 to 450 kcal per cup. For large breeds, ensure calcium and phosphorus levels are appropriate for bone health. Omega-3 fatty acids from fish oil support skin and coat health. Avoid foods with excessive fillers like corn or wheat.

How we chose these picks

  • Reviewed ingredient lists for named protein sources and absence of artificial additives.
  • Evaluated kibble shape and texture for dental benefits.
  • Checked AAFCO nutritional adequacy statements.
  • Considered protein, fat, and fiber content for balanced nutrition.
  • Included products from reputable brands with rigorous quality control.
  • Read customer feedback on palatability and breath improvement.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Avoid foods with unnamed meat meals as the primary protein source.
  • Be cautious with grain-free or legume-heavy recipes due to the FDA DCM investigation; grain-inclusive is generally safer unless a vet advises otherwise.
  • Do not feed all-life-stages food to large-breed puppies; it may cause rapid growth and joint issues.
  • Switch foods gradually over 7 to 10 days to avoid digestive upset.

Why this matters

Bad breath in dogs is primarily caused by bacteria in the mouth, not the protein content itself. Choosing a kibble with a texture that mechanically cleans teeth can be more effective than simply increasing protein.

The Options

Types Explained

Dry Kibble

Crunchy kibble that provides mechanical cleaning action. Most convenient and cost-effective.

Best for: Dogs that need dental benefits and owners seeking affordable, shelf-stable food.

Wet Food

Higher moisture content, softer texture. Less effective for dental cleaning but can be mixed with dry food.

Best for: Dogs with dental pain or picky eaters that refuse dry food.

Dental Diet

Veterinary-formulated with specific kibble size and shape to reduce plaque and tartar. Often requires a prescription.

Best for: Dogs with existing dental disease or severe bad breath.

Grain-Inclusive Formula

Contains grains like rice or oats. Generally considered safer than grain-free due to DCM concerns.

Best for: Most dogs without grain allergies; provides balanced energy.

Purina Pro Plan Adult Shredded Blend Chicken & Rice Formula

View on Amazon

This formula combines high protein (26%) with crunchy kibble and tender shreds. The kibble texture helps reduce plaque and tartar, addressing bad breath. It includes natural prebiotic fiber for digestive health. A minor trade-off is that some dogs may prefer a single-texture food.

With 25% protein and easily digestible ingredients, this food supports both digestive health and oral hygiene. The kibble size is suitable for most breeds. However, it does not have a specific dental claim, so breath improvement may be indirect.

#3
Diamond Naturals Chicken & Rice Formula
Best Budget

Diamond Naturals Chicken & Rice Formula

View on Amazon

Offering 32% protein from chicken, this food includes probiotics and omega fatty acids. The crunchy kibble provides some mechanical cleaning. The main limitation is that it contains a higher protein level, which may not suit all dogs with bad breath if protein metabolism is a concern.

Best Grain-Inclusive

Wellness CORE Grain-Free Original Turkey & Chicken

View on Amazon

Though labeled grain-free, this recipe uses turkey and chicken for 34% protein. It includes probiotics and glucosamine. The kibble is small and crunchy. A trade-off is that grain-free diets are under FDA investigation for DCM, so consult your vet.

Best for Dental Health

Royal Canin Veterinary Diet Dental Dry Dog Food

View on Amazon

Specifically designed to reduce plaque and tartar, this food has a special kibble texture that brushes teeth. It contains 25% protein and balanced nutrients. However, it is a veterinary diet, so a prescription may be required, and it is pricier than over-the-counter options.

Before You Buy

Key Buying Factors

01

Kibble Texture and Shape

Larger, crunchy kibble can mechanically scrape plaque off teeth, reducing bad breath. Look for foods with a porous or fibrous texture that encourages chewing.

02

Protein Source Quality

Named meat meals or whole meats are preferable. High-quality protein is more digestible, producing fewer odorous compounds.

03

Added Breath-Freshening Ingredients

Some foods include parsley, chlorophyll, or yucca schidigera extract, which may help neutralize odors. These are not a substitute for dental care.

04

Omega-3 Fatty Acids

Omega-3s from fish oil reduce inflammation, which can improve gum health and indirectly reduce bad breath.

05

AAFCO Statement

Ensure the food is complete and balanced for your dog's life stage. Avoid foods that only say 'for intermittent feeding' unless used as a treat.

Living With It

Care, Cost and Maintenance

Regular Dental Checkups

Even with dental kibble, professional cleanings are essential. Schedule annual vet exams to check for periodontal disease, which is a common cause of bad breath.

Daily Tooth Brushing

Use a dog-specific toothpaste and brush to remove plaque. Aim for daily brushing; even a few times a week helps. Start slowly to acclimate your dog.

Provide Dental Chews

Offer dental chews approved by the Veterinary Oral Health Council (VOHC). These can supplement the mechanical cleaning from kibble.

Pro tip

Add a small amount of fresh parsley or mint to your dog's food occasionally. These herbs can naturally freshen breath, but ensure they are safe and used in moderation.

Frequently asked questions

How much high protein dog food should I feed my dog with bad breath?
Feeding amounts vary by brand and your dog's weight, age, and activity level. Check the feeding guide on the bag. Typically, a 50-pound dog needs about 2.5 to 3 cups per day of a 350 kcal/cup food. Start with the recommended amount and adjust to maintain a healthy body condition. Overfeeding can lead to obesity, which may worsen bad breath due to increased plaque.
How many calories does a dog with bad breath need daily?
Daily calorie needs depend on your dog's size and activity. A sedentary 30-pound dog may need around 700 to 900 kcal, while an active 60-pound dog might need 1,200 to 1,600 kcal. Use the food's calorie content per cup to calculate portions. Consult your vet for a precise recommendation, especially if your dog is overweight or has health issues.
Is grain-free dog food safe for dogs with bad breath?
Grain-free diets are not necessarily safer or better for bad breath. The FDA is investigating a potential link between grain-free, legume-heavy diets and canine dilated cardiomyopathy (DCM). Unless your dog has a confirmed grain allergy, grain-inclusive foods are generally recommended. Always discuss diet changes with your veterinarian.
Can I feed puppy food to my adult dog with bad breath?
Puppy food is higher in calories, protein, and certain minerals to support growth. Feeding it to an adult dog can lead to obesity and nutritional imbalances. If your adult dog has bad breath, choose an adult formula with appropriate protein levels and dental benefits. Puppy food is not recommended for adult dogs.
What should I feed an overweight dog with bad breath?
Choose a high protein, low calorie food with moderate fat. Look for formulas labeled 'weight management' or 'healthy weight.' These often have 25% to 30% protein and lower fat (10% to 15%). The crunchy kibble can still help with dental cleaning. Always measure portions and avoid free-feeding.
Is high protein dog food good for senior dogs with bad breath?
Senior dogs may benefit from moderate protein (25% to 30%) to maintain muscle mass, but excessive protein can stress kidneys if kidney disease is present. Choose a senior formula with added joint support and omega-3s. The kibble should be easy to chew. Consult your vet for kidney function testing before increasing protein.
What size or breed is best suited for high protein dog food?
High protein food can suit any breed, but large breed dogs need controlled calcium and phosphorus to prevent skeletal issues. Small breeds may need smaller kibble. For bad breath, all breeds benefit from dental kibble. Choose a formula designed for your dog's size and life stage.
Should I choose dry or wet food for my dog's bad breath?
Dry kibble is generally better for dental health because the crunching action helps scrape plaque. Wet food has higher moisture but does not clean teeth. A combination of dry food with occasional wet food can provide variety while maintaining dental benefits. If your dog has dental pain, wet food may be easier to eat.
Can high protein dog food cure bad breath?
No, high protein dog food alone cannot cure bad breath. Bad breath is often a sign of dental disease, oral infections, or other health issues. While a proper diet can help reduce odor, you should have your dog examined by a veterinarian to rule out underlying problems. Regular dental care is essential.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your pet's diet or care routine, especially if your pet has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
