Notes

  • Individual variation of ±10–15% is normal. Two Sussex Spaniel puppies from the same litter can sit at opposite ends of the 35–45 lb range at 14 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 14 months a Sussex Spaniel has essentially finished growing. Weight gain from here is body condition, not growth — and the fix is the bowl, not the calendar.
  • 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 14 months

40 lb is typical, and anything inside 35 – 45 lb is a healthy weight for this breed at this age.

That is about 100% of an adult {giong}, which averages 40 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 0 lb, with 0 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 35 – 45 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.
