A chubby puppy may look cute, but excess weight can have serious long-term consequences. Studies show that overweight puppies are more likely to develop joint problems such as osteoarthritis and tend to live shorter lives. Puppies kept at their ideal puppy weight enjoy better joint health, slower, controlled growth, and a longer lifespan.

Scientific Evidence: 14-Year Study in Labrador Retrievers

A landmark 14-year study by Purina followed 48 Labrador Retrievers divided into two groups: one group was fed 25% fewer calories than the other.

Key results:

• Lean-fed dogs lived 1.8 years longer (13.0 years vs. 11.2 years)
• Osteoarthritis symptoms began almost 3 years later
• At 8 years old, only 10% of lean-fed dogs had multi-joint arthritis vs. 77% in the control group
• Hip dysplasia at 2 years: 1/24 lean-fed vs. 6/24 control

 

This evidence highlights the importance of controlling puppy growth from an early age to maintain the ideal puppy weight.

Joint Stress Starts in Puppyhood

Bones and joints develop rapidly in puppies. Extra weight during growth places mechanical stress on immature joints, increasing the risk of deformities and arthritis. This is especially critical in large breeds.

What Does an Ideal Puppy Look Like?

Keeping your puppy at the ideal weight is easier if you know what to look for:

• Ribs should be easily felt with light pressure
• Waist should be visible from above
• The abdomen should, depending on body composition, tuck up slightly when viewed from the side. This can vary between breeds that are more “barrel-shaped” such as brachycephalic breeds or compact terriers, and breeds with anyways an obvious waist such as hounds. Don’t worry too much about this when the puppy is under 3-6 months old, but do consult your veterinarian regularly during vaccination visits!

Avoid Feeding Adult Dog Food to Puppies

Adult food is not designed for growing puppies – especially not for large breeds. It lacks the proper energy, protein, calcium and phosphorus ratio. Always use a complete puppy food, preferably labeled for large breed growth if applicable.

Raw or Home-Cooked? Only with Expert Planning

Homemade or raw diets can work, but only with precise planning. Common risks include:

• Calcium deficiency → soft bones
• Vitamin D and phosphorus imbalance → growth disorders
• Excess energy → rapid growth and joint stress
