The Big Picture: What the New Science Says

Homemade and raw diets are booming in the UK

– 1 in 5 owners now feed some form of non-commercial food. But 2025’s global research is sounding the alarm:

unbalanced recipes are causing real harm. From fractured bones to bacterial nightmares, here’s the latest evidence from the UK, USA, Europe, and beyond – no hype, just hard data.

1. The Bone-Breaking Truth:

Vitamin D & Calcium Deficiencies

A giant schnauzer puppy in the USA developed vitamin D deficiency, fractured vertebrae, and hyperparathyroidism – all from a homemade diet missing calcium and D.

UK Mirror Case: A 2025 study from the Royal Veterinary College (RVC) found 12% of UK puppies on homemade diets showed early rickets signs (soft bones, bow legs).

Source: RVC Pandemic Puppies Project Survey  Global Stat: 40% of growth problems in puppies come from unbalanced homemade or raw diets.

3. The “All-Meat” Myth: Protein Imbalance Kills

Feeding only meat (no organs, bones, or veg) causes:

Muscle wasting

Anaemia

Immune failure

4. The UK’s Pandemic Puppies: A Raw Diet DisasterThe RVC Pandemic Puppies Project (4,000+ dogs) found:

Lockdown pups on raw/homemade diets were 2.5× more likely to have behaviour issues (fear, aggression).

16% showed separation anxiety – linked to nutrient gaps affecting brain development.
