Quick answer

For most Maltese dogs, Purina FortiFlora is our top pick because it contains a single well-studied probiotic strain (Enterococcus faecium) at a guaranteed potency and is easy to sprinkle on food. If your Maltese prefers a chewable, Zesty Paws Probiotic Bites offer multiple strains and prebiotics. For seniors with joint concerns, Nutramax Proviable-DC combines probiotics with prebiotics in a capsule that can be opened.

What to consider for Dog Probiotic For Maltese Dogs

Maltese dogs are prone to sensitive stomachs, food allergies, and dental issues. When choosing a probiotic, consider the strain diversity (multiple strains may support different functions), CFU count (typically 1 to 10 billion CFU per day for small dogs), and delivery form (powders are easy to mix, chews are convenient but may contain fillers). Also check for prebiotics like FOS to feed good bacteria. Always consult your vet before starting any supplement.

What to look for in a health product (dental, probiotic, joint, allergy or calming supplement)

Look for an NASC quality seal to ensure manufacturing standards. For probiotics, choose products with guaranteed live cultures until the expiration date, not just at manufacture. Evidence-based ingredients should be present at meaningful amounts: for probiotics, strains like Enterococcus faecium, Bifidobacterium animalis, and Lactobacillus acidophilus are well-studied. Dosing should be weight-appropriate; many small-breed formulas exist. Avoid products with vague proprietary blends or unlisted amounts.

How we chose these picks

  • Evaluated products based on ingredient transparency and strain diversity.
  • Checked for third-party quality seals like NASC.
  • Prioritized products with guaranteed CFU through expiration.
  • Considered ease of use for small dogs (powder, chewable, or capsule).
  • Reviewed customer feedback for palatability and digestive benefits.
  • Ensured products are from reputable pet supplement brands.
  • Excluded products with artificial additives or excessive fillers.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Products claiming to cure or prevent diseases like pancreatitis or IBD without veterinary oversight.
  • Human probiotics, as they may contain strains not suited for dogs.
  • Vague proprietary blends that do not list individual strain amounts.
  • Exceeding the labelled dose, which can cause digestive upset.

Maltese dogs often suffer from sensitive digestion and small appetites, making a high-quality, low-filler probiotic essential. The best choice balances strain diversity with guaranteed potency and easy administration.

Capsule Probiotics

Capsules can be given whole or opened and sprinkled on food. They often contain multiple strains and are stable at room temperature.

Best for: Dogs that need a higher CFU count or specific strain combinations.

Purina FortiFlora Probiotic for Dogs, Supplement for Digestive Health
Best Overall

Purina FortiFlora Probiotic for Dogs, Supplement for Digestive Health

View on Amazon

FortiFlora is a veterinary-recommended powder with a single strain (Enterococcus faecium) at a guaranteed potency of 1 billion CFU per packet. It's easy to mix into food and is well-tolerated by sensitive Maltese stomachs. However, it lacks multiple strains and prebiotics, so dogs needing broader gut support might benefit from a multi-strain option.

Best Budget

VetriScience Probiotic Everyday for Dogs and Cats

View on Amazon

VetriScience offers a simple, affordable probiotic powder with Enterococcus faecium and a guaranteed CFU of 1 billion per scoop. It is made in the USA and has minimal ingredients, reducing allergy risks.

Before You Buy

Key Buying Factors

01

Strain Diversity

Multiple probiotic strains can support different aspects of gut health. For Maltese, look for products with at least two to three strains, such as Enterococcus faecium, Bifidobacterium animalis, and Lactobacillus acidophilus.

02

CFU Count

Colony-forming units (CFU) indicate the number of live bacteria. For a Maltese weighing 4 to 7 pounds, a daily dose of 1 to 5 billion CFU is generally appropriate. Higher CFU is not always better and may cause gas.

03

Delivery Form

Powders are easy to mix into wet food, chews are convenient but may contain more fillers, and capsules can be opened. Choose based on your dog's preference and your convenience.

04

Quality Assurance

Look for products with an NASC quality seal, which verifies manufacturing standards. Also check that the CFU is guaranteed through the expiration date, not just at the time of manufacture.

05

Prebiotics and Additives

Prebiotics like FOS or inulin feed beneficial bacteria. Avoid products with artificial colors, flavors, or excessive fillers like corn or wheat, which may trigger allergies in sensitive Maltese.

Living With It

Care, Cost and Maintenance

Introducing Probiotics

Start with a half dose for the first few days to allow your Maltese's digestive system to adjust. Gradually increase to the full recommended dose over a week. Monitor for any signs of gas or loose stool, which usually resolve within a few days.

Storage and Expiration

Most probiotics require cool, dry storage. Some need refrigeration after opening; always check the label. Discard any product past its expiration date, as live bacteria counts decline over time.

When to Consult a Vet

If your Maltese experiences persistent vomiting, diarrhea, or weight loss, consult your veterinarian before starting probiotics. Also seek veterinary advice if your dog has a compromised immune system or is on long-term antibiotics.

Pro tip

Mix powdered probiotics with a small amount of warm (not hot) wet food to activate the bacteria, and serve immediately to maximize live cultures.

Frequently asked questions

Do dog probiotics really work for Maltese dogs?
Probiotics can support digestive health by balancing gut bacteria. Many Maltese owners report improvements in stool quality and reduced gas. However, results vary by individual. Probiotics are not a cure-all and should be used alongside a balanced diet. Always consult your vet to determine if probiotics are appropriate for your dog's specific condition.
How should I dose a probiotic for my Maltese?
Dosing depends on the product and your dog's weight. Most probiotics for small dogs recommend 1 to 5 billion CFU per day. Start with the lower end of the recommended dose and monitor your dog's response. If using a powder, mix it thoroughly with wet food. For chews, follow the package instructions. Never exceed the labelled dose without veterinary guidance.
When should I see a vet about my Maltese's digestive issues?
If your Maltese has persistent vomiting, diarrhea lasting more than 24 hours, blood in stool, lethargy, or weight loss, consult your vet immediately. Probiotics may help with mild digestive upset, but they are not a substitute for professional medical care. Your vet can rule out underlying conditions like pancreatitis or food allergies.
What should I look for in a high-quality dog probiotic?
Look for products with an NASC quality seal, which indicates third-party auditing of manufacturing practices. Choose probiotics that list specific strains and guarantee CFU through the expiration date. Avoid products with vague proprietary blends. Multi-strain formulas may offer broader benefits, but single-strain options can be effective for targeted support.
Should I choose a joint supplement or probiotic for my Maltese?
It depends on your dog's primary needs. Probiotics target digestive health, while joint supplements (containing glucosamine and chondroitin) support mobility. Some products combine both, but it's often better to address one issue at a time. If your Maltese has both digestive and joint concerns, consult your vet about using separate supplements at appropriate doses.
Can probiotics help with my Maltese's allergies?
Some studies suggest probiotics may modulate the immune system and reduce allergic responses, but evidence is limited. Probiotics are not a treatment for allergies. They may support overall gut health, which can influence skin and coat condition. For allergy symptoms like itching or ear infections, consult your vet for proper diagnosis and treatment.
Are dental chews safe for Maltese dogs?
Dental chews can be safe if they are appropriately sized for small breeds. Look for products with the VOHC seal of acceptance. However, some chews are high in calories or may pose a choking hazard. Always supervise your Maltese while chewing and choose chews that are soft enough to avoid tooth fractures. Consult your vet for recommendations.
Can I give my Maltese a human probiotic?
It is not recommended. Human probiotics often contain strains that are not beneficial for dogs and may cause digestive upset. Dog-specific probiotics are formulated with canine gut flora in mind. Stick to products labeled for dogs to ensure safety and efficacy.
Are there any risks or side effects of probiotics for Maltese?
Probiotics are generally safe, but some dogs may experience mild gas, bloating, or loose stools when first starting. These symptoms usually resolve within a few days. Rarely, dogs with compromised immune systems may develop infections from live bacteria. Always consult your vet before starting probiotics, especially for puppies or senior dogs with health issues.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
