Small dogs are not just scaled-down large dogs. Their metabolic rate is higher, their digestive tract is proportionally shorter, and they can be far more sensitive to dietary change.
If you are moving your dog onto Thrive Origins, it is essential to transition correctly — especially if they are under 10kg.
A rushed switch is the single biggest mistake owners make when moving from processed food to a biologically appropriate raw diet.
Let’s break this down properly.
What Your Dog Has Likely Been Eating
Most small dogs have been raised on:
- Commercial kibble (highly processed, high-carbohydrate)
- Tinned wet food (often thickened with gums and starches)
- Cooked protein diets with limited variety
- Low-fat, low-organ, low-marine content formulations
These diets typically:
- Contain low natural enzymes
- Have minimal microbial diversity
- Include little to no fresh organ meat
- Rarely include whole sardines or mackerel
- Contain synthetic vitamins rather than whole-food micronutrients
When you introduce Thrive, you are introducing:
- Fresh venison or ostrich muscle meat
- Whole sardines or mackerel
- Fresh liver and kidney
- Whole eggs
- Natural phytonutrients
This is a significant upgrade — but the gut must adapt.
What Happens When You Introduce Fish and Liver
Sardines or Mackerel
Oily fish is powerful nutrition.
It introduces:
- Omega-3 fatty acids (EPA & DHA)
- Iodine
- Marine minerals
- New proteins the immune system may not have encountered
If your dog is not accustomed to marine protein, you may see:
- Loose stool
- Slight fishy odour to stool
- Mild mucus coating stool
This is not usually an allergy.
It is a microbial adjustment phase.
The gut bacteria that digest marine fats may not yet be dominant. As those populations expand, tolerance improves.
Liver and Organ Meats
Liver is one of the most nutrient-dense foods on the planet.
It delivers:
- Pre-formed vitamin A
- Copper
- B vitamins
- Bioavailable iron
If a dog has never eaten fresh liver before, the body responds strongly.
You may see:
- Softer stool
- Darker stool
- Transient mucus
- In rare cases, small streaks of blood from colonic irritation
This is usually due to:
- Increased bile flow
- A detoxification response
- Rapid microbial fermentation shifts
It is not typically a cause for alarm if:
- The dog remains bright
- Appetite is normal
- There is no persistent vomiting
- Symptoms resolve within 24–72 hours
However, persistent blood, lethargy, or ongoing diarrhoea should always be evaluated by your veterinarian.
Why This Happens: The Microbiome Shift
Your dog’s gut microbiome reflects what they have been fed.
A high-carbohydrate processed diet promotes:
- Sugar-fermenting bacteria
- Lower bile tolerance
- Reduced fat-digesting species
A fresh, whole-food diet promotes:
- Proteolytic bacteria
- Fat-adapted microbes
- Greater microbial diversity
- Stronger mucosal integrity
The shift takes time.
The body must:
- Increase digestive enzyme production
- Adjust bile secretion
- Rebalance intestinal flora
When done correctly, this transition strengthens the gut long term.
The Thrive Transition Protocol
(For Dogs Under 10kg)
Small dogs require a slower progression.
Step 1: Start at 10–15% Thrive
For Days 1–3:
- 85–90% current food
- 10–15% Thrive
Feed twice daily to reduce digestive load.
Monitor stool consistency.
Step 2: Increase to 25%
Days 4–6:
- 75% current food
- 25% Thrive
If stool softens, hold at this level for an additional 2–3 days before increasing.
Step 3: 50% Phase
Days 7–10:
- 50% current food
- 50% Thrive
At this stage, the microbiome is actively adapting.
You may notice:
- Slightly softer stool
- Increased stool volume (temporarily)
- Mild odour change
This is expected.
Step 4: 75%
Days 11–14:
- 25% old food
- 75% Thrive
Energy levels often begin to shift noticeably here.
Step 5: 100% Thrive
After 14 days (sometimes 21 days for sensitive dogs), transition fully.
If your dog has:
- A history of gut sensitivity
- Chronic loose stool
- Previous antibiotic use
Extend the transition to 3–4 weeks.
There is no prize for speed.
When to Slow Down
Pause or reduce if you see:
- Repeated watery diarrhoea
- Ongoing fresh blood
- Vomiting
- Lethargy
Mild mucus or temporary softness is acceptable. Persistent symptoms are not.
Expected Benefits After Full Transition
Once adapted, small dogs often demonstrate:
- Firmer, smaller stools
- Reduced stool odour
- Improved coat gloss
- Cleaner teeth
- Improved muscle tone
- Stable energy without sugar spikes
- Reduced itching in many cases
- Better breath
Most importantly:
Improved metabolic resilience.
You are feeding biologically appropriate nutrition rather than ultra-processed filler.
Final Perspective
Transitioning to Thrive is not simply changing food.
It is changing the metabolic environment of your dog.
A short adaptation phase is normal.
A stronger gut, better immunity, and long-term vitality are the reward.
Move steadily.
Observe carefully.
Allow the biology to recalibrate.
If done correctly, the Thrive diet does not merely feed your dog — it strengthens them
