What is a Good Probiotic for Dogs?

A good probiotic for dogs is a living microorganism that provides a health benefit when served appropriately.

The dog’s gastrointestinal system harbors billions of microorganisms, including beneficial and harmful bacteria and certain yeasts. The various microorganisms are balanced in optimal conditions, forming the gut microbiome.

Probiotics for dogs are available in supplement form and are naturally found in certain foods. Using dog probiotics helps keep the gut microbiome balanced.

How does Probiotics Work for Dogs?

Probiotics for dogs work by supporting a healthy microbiome, adjusting the gut’s acidity, and releasing beneficial fatty acids.

Probiotics introduce healthy bacteria and yeasts into the GI tract. The beneficial microbes inhibit the growth of bad ones by competing with them for nutrients.

A high-quality probiotic supplement for dogs works naturally and is safe for dogs of all ages and sizes.

Why a Dog Needs Probiotics?

A dog needs probiotics to restore microbial gut balance. Regularly using probiotics for dogs results in healthy digestion, improved nutrient resorption, a strong immune system, fresh breath, fewer allergies, ear infections, and GI tract conditions.

When should you Give Probiotics for your Dogs?

You should give probiotics for your dogs in times of gut microbiome imbalances. Give probiotics when dogs have diarrhea and before events that follow diarrhea, like pet food changes and stressful car rides.

Probiotics are suggested for dogs with allergy-triggered skin issues, bad breath, and recurring ear infections. Administer probiotics during and after long-term antibiotic treatments.

Can You Give Probiotics to Puppies?

Yes, you can give probiotics to puppies. Veterinarians recommend using puppy probiotics for the treatment of diarrhea. Diarrhea is common in puppies due to their sensitive stomachs that result from puppy anxiety.

Always consult the vet before giving probiotics to puppies, and ensure the supplement is made exclusively for dogs.

How can Probiotics Improve Dogs' Digestive Health?

Probiotics improve the dog’s digestive health by balancing gut bacteria. Probiotics help treat and prevent digestive problems in dogs while aiding digestion and promoting nutrient production and absorption.

Probiotics for dogs are beneficial in treating many gastrointestinal (GI) tract diseases, including enteritis and inflammatory bowel disease, and help ease digestive symptoms like diarrhea, constipation, bloat, gassiness, and abdominal pain.

How do Probiotics for Dogs Help Boost the Immune System?

Probiotics for dogs help boost the immune system by supporting a healthy gastrointestinal tract.

The dog’s digestive tract comprises roughly 70% of the dog’s immune system. Managing problems in the gut boosts dog immunity by allowing the immune system to work properly.

Probiotics for dogs benefit immunity, according to the paper “Oral Administration of Compound Probiotics Improved Canine Feed Intake, Weight Gain, Immunity and Intestinal Microbiota,” published in Frontiers in Immunology in 2019.

Can Probiotics for Dogs Prevent Dog Autoimmune Diseases?

No, probiotics for dogs do not prevent autoimmune diseases. “Probiotics have shown therapeutic potential toward immune-mediated diseases” in humans, according to a study, “Probiotics and Prebiotics in the Suppression of Autoimmune Diseases,” published in A Scientific Perspective in 2022. The effect of pet probiotics based on current research does not indicate the prevention or treatment of autoimmune disease in dogs.

What are the Benefits of Probiotics for Dogs?

The benefits of probiotics for dogs are listed below.

  • Improved Digestive Health: Probiotics support digestive health and help treat various GI tract conditions. Probiotics enhance nutrient absorption, promote stool quality, and reduce the risk of hookworm infections.
  • Oral Health and Breath Support: Certain dog probiotic strains support oral health and have an antimicrobial effect, reducing the risk of periodontal (gum) disease. Probiotics prevent halitosis or bad breath in dogs.
  • Stronger Immune System: Probiotics for dogs boost the immune system. They increase the immune potency of the colostrum (first milk) in pregnant dogs, resulting in puppies with stronger viral resistance.
  • Allergy and Allergy Symptom Control: Probiotics help reduce allergies by stimulating the dog’s immune system and relieving certain allergy symptoms, including ear infections and itchiness.
  • Better Mood and Relaxation: Certain probiotic strains (behavioral probiotics) target the dog’s mood and relieve anxiety. Probiotics affect mood through the gut-brain axis.

What are the Risks of Probiotics for Dogs?

The risks of probiotics for dogs are listed below.

  • Diarrhea: Diarrhea that manifests with frequent or loose stool is the most common side effect of probiotics for dogs and a telltale sign of stomach upset.
  • Constipation: Dog probiotics occasionally cause constipation. A constipated dog has trouble defecating.
  • Excess Gas: The sudden changes in the gut microbiome caused by the probiotic result in increased gas production by the bacteria.
  • Bloating: The excess gas produced by the gut bacteria accumulates in the dog’s digestive tract, causing bloating and abdominal pain.

How Often Should You Give Probiotics to Dogs?

You should give probiotics to dogs daily. The duration and frequency of administration depend on the dog’s health and the reason for using probiotics.

For example, a dog prone to travel diarrhea benefits from temporary probiotic supplementation before the trip. A dog on long-term antibiotic therapy requires probiotic support while taking the antibiotics. A dog with allergies needs continuous probiotic support for symptom relief.

Consult the veterinarian to ensure responsible use of probiotics for dogs.

How to Make Homemade Probiotics for Your Dogs?

To make homemade probiotics for your dogs, follow the instructions listed below.

  • Gather the Ingredients: Measure 1⅓ cups of plain yogurt (home-prepared if possible), ⅓ of freshly chopped parsley, and ⅓ cup of finely shredded carrots.
  • Prepare the Equipment: Have a mixing bowl and silicon molds or an ice cube tray on hand before mixing the recipe.
  • Mix the Ingredients Together: Combine the chopped veggies with the measured yogurt amount in a bowl and mix them well.
  • Spoon the Paste into the Mold/Tray: Spoon the veggie-yogurt mixture into the silicone molds or ice cube tray based on preference and availability.
  • Freeze the Recipe: Place the treats in the freezer for several hours to harden and serve them as tasty, nutrient-rich homemade probiotics for dogs.

Can Probiotics Treat Allergies in Dogs?

Yes, probiotics treat allergies in dogs. Probiotics for dogs decrease immune hyperreactivity and reduce allergen-triggered inflammation.

Probiotics restore gut health, boost immunity, and help treat dog allergy issues, especially seasonal environmental hypersensitivity and canine atopic dermatitis.

Probiotics modulate the immune response and may have protective effects against atopic dermatitis, according to a study published in Veterinary Immunology and Immunopathology in 2012. The study titled “Early Exposure to Probiotics in a Canine Model of Atopic Dermatitis Has Long-Term Clinical and Immunological Effects.”

Are Probiotics for Humans Safe for Dogs?

No, human probiotics are not safe for dogs. Human probiotics feature a higher number of colony-forming units (CFUs) than dog probiotics.

Probiotics designed for humans contain added ingredients that are harmful to dogs. For example, certain human probiotics feature xylitol. Xylitol is an artificial sweetener that is extremely toxic to pets.

Certain human probiotics are safe for dogs, but the range of probiotics for dogs available on the market means it is best to avoid human formulas.

What Factors Should Dog Owners Consider When Choosing Probiotic Supplements?

The factors dog owners should consider when choosing probiotic supplements are listed below.

  • Number of Strains: Probiotics for dogs feature one or more unique strains of bacteria. Single-strain products target specific health problems, and multi-strain probiotics support overall wellness.
  • Colony-Forming Units (CFUs): The colony-forming units represent the number of good bacteria in the probiotic. The more CFUs in the supplement, the higher its potency.
  • Ingredient List: A quality dog probiotic must be free from allergens and artificial ingredients and contain healthy additions, such as prebiotics, fatty acids, antioxidants, vitamins, and minerals.
  • Brand: Research the brand before choosing the ideal dog probiotics. Read reviews from previous customers and consider the brand’s transparency regarding ingredients and manufacturing practices.
  • Form and Flavor: Probiotics for dogs come in different forms (powder, capsules, treats) and dog-friendly flavors (beef, chicken). Choose the combination that is simplest to serve.

How do Veterinarians Determine the suitable Probiotics for your Dog?

Veterinarians determine the suitable probiotics for your dog based on individual needs. Certain health issues benefit from specific probiotics for dogs.

For example, veterinarians administer probiotics with Enterococcus faecium to decrease the duration of acute diarrhea episodes, while they recommend probiotics rich in Bifidobacterium longum for anxiety relief.
