Notes

  • Individual variation of ±10–15% is normal. Two Cocker Spaniel puppies from the same litter can sit at opposite ends of the 14–21 lb range at 6 months and both be healthy. The shape of the curve matters more than any single reading: steady gain month over month is the thing to watch, not whether this week matches a chart.
  • Medium breeds reach adult weight at around 14 months, which is why this is not one curve for all dogs. Bigger dogs grow for longer, and feeding a large-breed puppy on a small-breed timetable is the most common way owners overshoot.
  • At 6 months this puppy still has 8 months of growing left and should gain roughly 1.5 lb over the next month. A month with no gain at this stage is worth a vet call; a month with double the expected gain usually means the food is being measured by eye.
  • Weigh on the same scale, same time of day, ideally before a meal. Puppy weights swing by several percent across a day, and comparing a morning weight to an evening one invents a change that never happened.
  • Ribs are the better test. You should feel them easily under a thin layer, without pressing. That check works at every age and on every breed, which is more than any chart can claim.

A {giong} at 6 months

17.5 lb is typical, and anything inside 14 – 21 lb is a healthy weight for this breed at this age.

That is about 70% of an adult {giong}, which averages 25 lb.

Why there is no single puppy growth chart

{giong} is a medium breed, and medium breeds finish growing at around 14 months. Small dogs are done by their first birthday; giant breeds are still filling out well into their second year.

That single fact is why a chart built for one size is wrong for another — and feeding a large-breed puppy on a small-breed timetable is the most common way owners overshoot.

What to expect next month

About 1.5 lb, with 8 months of growing left.

A month with no gain at this stage is worth a phone call to the vet. A month with double the expected gain almost always means the food is being measured by eye rather than weighed.

The ±10–15% nobody prints on the chart

Two puppies from the same litter can sit at opposite ends of the 14 – 21 lb range and both be perfectly healthy. The shape of the curve matters more than any single reading — steady gain month over month is the thing to watch.

Weigh on the same scale, at the same time of day, before a meal. Puppy weight swings by several percent across a day, and comparing a morning number to an evening one invents a change that never happened.

The test that works at every age

Run your hands along the ribs. You should feel them easily under a thin layer, without pressing.

That check works on every breed and every month of the chart above, which is more than any number can claim.
