BiFido for Fido

BiFido for Fido is a veterinary-formulated multi-strain probiotic for dogs — 50 billion CFU across 13 carefully selected probiotic strains, combined with Saccharomyces boulardii (a probiotic yeast), fructooligosaccharides (FOS), and organic Jerusalem artichoke inulin. Designed to support dogs through occasional flare-ups of digestive distress — loose stools, gas, gut upset from dietary changes, or the aftermath of medications.

Each strain is chosen for its ability to survive stomach acid and deliver benefit in the canine gut. Together they help maintain a healthy intestinal tract, support proper gut flora balance, and aid in the production of B vitamins, vitamin K, short-chain fatty acids, and digestive enzymes. Unlike soil-based probiotics designed for daily maintenance, BiFido is formulated for targeted, short-course use during digestive upset. Available in 50.1g.

"Not all probiotics are probiotics" — Four Leaf Rover's guiding principle when formulating BiFido. Every strain in the blend is backed by research showing its specific benefit in dogs (or close analogues in humans) and its ability to survive stomach acid to reach the gut. This is a curated blend, not a scattergun approach. Together they deliver 50 billion CFU daily for a large dog — a meaningful therapeutic dose designed to move the needle during acute digestive upset.

Bifidobacterium bifidum, Bifidobacterium longum, and Bifidus animalis live naturally in the colon and play a central role in stool formation, gut lining support, and immune balance. When digestive upset strikes — loose stools, irregular bowel movements, post-antibiotic imbalance — it's often Bifidobacterium populations that have been depleted. BiFido is named for this family of strains because they do most of the heavy lifting in resolving acute digestive distress.

Lactobacillus acidophilus, L. bulgaricus, L. casei, L. paracasei, L. plantarum, L. salivarius, and L. rhamnosus work primarily in the small intestine. They aid digestion, support nutrient absorption, and help crowd out harmful bacteria. Several strains — particularly L. rhamnosus and L. acidophilus — are among the most researched probiotics in veterinary medicine for acute gastrointestinal support.

BiFido for Fido also contains Saccharomyces boulardii, a probiotic yeast rather than a bacteria. Because it's a yeast, S. boulardii is not destroyed by antibiotics, making it useful support for dogs recovering from antibiotic-related digestive disruption. It also helps defend against Candida and other problematic yeast, and is particularly effective against antibiotic-associated diarrhoea.

Enterococcus faecium supports microbial balance and healthy elimination. Streptococcus thermophilus helps stabilise the gut environment and can ease digestive discomfort. Both are well-researched in acute gastrointestinal contexts and round out BiFido's comprehensive strain coverage.

Probiotics without prebiotics are like seeds without soil — they won't establish. BiFido includes two food-grade prebiotics: fructooligosaccharides (FOS, 851mg) and organic inulin from Jerusalem artichoke (570mg). Together they feed the beneficial bacteria you've just introduced, supporting colonisation and helping the microbiome shift back into balance faster than probiotics alone.

BiFido is the Four Leaf Rover probiotic to have on hand for when things go wrong. Occasional loose stools from dietary indiscretion. Gut upset after a medication course. Digestive irregularity following travel, stress, or a food change. The recovery phase after a bout of GI illness. It delivers high-CFU, multi-strain, research-backed support right when a dog needs it — and is best used as a focused intervention rather than a daily supplement. For everyday probiotic maintenance and environmental toxin clearance, Protect is the better choice. For repairing a compromised gut lining, Gut Guard is the targeted formula.

Every batch of BiFido for Fido is third-party tested for pesticides, heavy metals, and microbial contaminants, with a Certificate of Analysis available on request. Four Leaf Rover holds the NASC Quality Seal — the benchmark for quality control in the pet supplement industry — and is certified Plastic Negative by rePurpose Global, removing twice the plastic from the environment that it creates. Manufacturing is GMP-compliant. Ingredients are sourced from trusted suppliers across New Zealand, North America, and Europe, with organic chosen wherever possible.

Proprietary Probiotic Blend — 50 Billion CFU daily for a large dog, including: Bifidobacterium bifidum, Bifidobacterium longum, Bifidus animalis, Enterococcus faecium, Lactobacillus acidophilus, Lactobacillus bulgaricus, Lactobacillus casei, Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus salivarius, Lactobacillus rhamnosus, Saccharomyces boulardii, Streptococcus thermophilus.

Free from: preservatives, fillers, binders, synthetics, artificial flavourings, artificial colourings, GMO ingredients, gluten, and dairy.

Give once or twice daily, mixed into food. Measure according to your dog's body weight using the guide below. For acute digestive upset, twice-daily dosing is often more effective in the first few days.

A 50.1g jar typically lasts anywhere from around three weeks to several months depending on your dog's size and whether BiFido is used daily or only during flare-ups. For most dogs, one jar covers several acute episodes.

Store in a cool, dry place away from direct sunlight. Refrigeration is not required but will extend probiotic viability. Keep the lid tightly sealed to maintain potency.
