Proactive Paws Primitive Probiotics™

The Future of Pet Probiotics Starts Here

Most pet probiotics on the market are human strains, never adapted to the metabolic, immune, or thermal environment of dogs. They’re not designed to survive the journey through a carnivore’s GI tract and accomplish a specific purpose. And many lack evidence of efficacy in the species they’re sold for.

That’s why Dr Karen Becker, a functional medicine veterinarian, and her tea of microbiome scientists, developed PRIMITIVE PROBIOTICS™. It is a radically different, science-driven approach to rebuilding and maintaining your dog’s microbiome using the very strains nature intended: from wild canids, healthy domestic dogs, and living soil.

If you’re looking for a dog probiotic that truly works, PRIMITIVE PROBIOTICS™ is the answer. This canine probiotic supplement is specifically formulated for dogs, ensuring optimal gut health, better digestion, and a stronger immune system. Unlike generic options, our species-specific strains are designed to thrive in your dog’s unique gastrointestinal environment.

• Today's domestic dogs face modern challenges their wild counterparts never encountered: 

• Frequent antibiotic / medication exposure that disrupts the microbiome 

• Urban environments, increased environmental pollutants 

• Highly processed diets

• Chronic low-grade inflammation

• Reduced microbial diversity due to indoor lifestyles

Why is Primitive Probiotics™ the best probiotic for dogs?

1. Ancestral strains 

These strains are isolated from wild wolves and represent the ancient microbial allies that dogs evolved with: robust, immune-priming, and genetically aligned with the canine body.

2. Species-specific strains

Sourced from healthy domestic dogs, these strains are uniquely adapted to the stressors and diets of modern life. They're highly colonizable for digestion, immunity, and stress tolerance. 

3. Soil-based organisms (SBOs)

Spore-forming probiotics like Bacillus subtilis and Bacillus clausii are natural survivors. They resist heat, stomach acid, and antibiotics; modulating inflammation and restoring balance when your dog needs it most.

FAQs

What makes Primitive Probiotics™ different from other dog probiotics?

Primitive Probiotics™ combines ancestral strains from wild wolves, species-specific strains from healthy domestic dogs, and ultra-resilient soil-based organisms (SBOs). This unique 3-in-1 formula delivers unmatched microbial diversity and survives stomach acid to truly transform your dog's gut health

How long before I start to see results?

Most dogs experience better stool quality and less gas within 24 - 48 hours. Calmer moods and reduced itching typically appear within 1 - 2 weeks, with stronger immunity and sustained energy by week 4. 

Is Primitive Probiotics™ safe for puppies and senior dogs?

Yes. It is vet-formulated and safe for dogs of all ages, including puppies building a strong microbiome and seniors needing extra digestive and immune support.

Can this help my dog with anxiety or aggression issues?

Primitive Probiotics™ includes GABA-producing LP815, clinically shown to reduce anxiety, improve mood, and promote restful sleep, making it ideal for anxious or high-string dogs.

If my dogs has taken or is taking antibiotics, when should I give Primitive Probiotics™?

If your dog has recently finished a course of antibiotics, give Primitive Probiotics with meals to help rebuild and restore the microbiome. If your dog is currently taking antibiotics, administer Primitive Probiotics at least 4 hours before or after the antibiotic dose - never at the same time - to ensure both work effectively. 

What food best pairs with probiotics?

Organic pumpkin fibre is a whole-food digestive superfood. With both soluble and insoluble fibre, it supports nutrient absorption, regular stools, and a balanced gut environment where probiotics thrive. Rich in vitamins, minerals, and antioxidants, pumpkin also nourishes the gut lining, calms inflammation, and strengthens immune defences. Unlike isolated probiotics that can trigger SIBO, pumpkin is gentle, effective, and biologically appropriate, making it the ideal partner for probiotics.
